  • Glass-forming ability and mechanical properties of Ti-based bulk glassy alloys with large diameters of up to 1 cm
    Intermetallics, 2008
    Co-Authors: Xinmin Wang, Akihisa Inoue
    Abstract:

    Abstract Ti–Zr–Cu–Pd–Sn bulk glassy alloys have been synthesized by Copper Mold casting. The thermal properties, glass-forming ability (GFA) and mechanical properties were examined by differential scanning calorimetry (DSC), differential thermal analysis (DTA), X-ray diffractometry (XRD) and compression test. The series of bulk glassy alloys is expected to be used as biomedical materials because of the absence of toxic elements such as Ni, Al and Be. The 10 mm rods with full glassy structure can be obtained for the Ti40Zr10Cu34Pd14Sn2 and Ti40Zr10Cu32Pd14Sn4 alloys by Copper Mold casting. The Ti40Zr10Cu36−xPd14Snx (x = 0, 2, 4, 6) glassy alloys have a large supercooled liquid region of over 50 K. The Ti40Zr10Cu34Pd14Sn2 bulk glassy alloy exhibits good plasticity of 3.5% during compressive applied load at ambient temperature in conjunction with distinct yield strain of 2.2% and high fracture strength of about 2050 MPa.

  • Chill zone Copper with the strength of stainless steel and tailorable color
    Acta Materialia, 2008
    Co-Authors: Alain Reza Yavari, Konstantinos Georgarakis, A. Lemoulec, F. Charlot, Gavin Vaughan, A.l. Greer, Akihisa Inoue
    Abstract:

    Abstract We report here on 90 at.% Copper 2–4 mm thick castings with fracture strengths up to 1.9 MPa due to the formation of a thick, scratch-resistant nanocrystalline chill-zone next to the Copper Mold contact surfaces. It is found that the unusually hard nanocrystalline surface layers of thicknesses in the range of 200–300 μm form when the melt can be undercooled: when the alloy composition is such that the contact surface of the Copper Mold with the liquid alloy does not serve as a preferred site for crystal nucleation, supercooling of the melt in the chill-zone is possible. These castings are the hardest Coppers ever reported to date in macroscopic specimens. They have mechanical strength superior to those of many stainless steels as well as to Cu–Be alloys and of the order of those of Cu-based bulk metallic glasses (BMGs) of similar dimensions. In addition, and unlike in Copper-based BMGs, the color and luster can be tailored by elemental additions to vary from Copper-like to gold-like.

  • preparation of cu36zr48ag8al8 bulk metallic glass with a diameter of 25 mm by Copper Mold casting
    Materials Transactions, 2007
    Co-Authors: Qingsheng Zhang, Wei Zhang, Akihisa Inoue
    Abstract:

    The Cu 36 Zr 48 Ag 8 Al 8 alloy exhibits very high glass-forming ability. We have succeeded in synthesizing a Cu 36 Zr 48 Ag 8 Al 8 bulk glassy alloy with a diameter of 25 mm using the conventional Copper Mold injection casting. The absence of a crystalline phase was confirmed by X-ray diffraction and differential scanning calorimetry examinations. The critical cooling rate for formation of a glassy phase for the Cu 36 Zr 4 Ag 8 Al 8 alloy was estimated to be less than 6.4 K/s. High glass-forming ability and high strength might contribute to its commercial application for the Cu 36 Zr 48 Ag 8 Al 8 bulk metallic glass.

  • New Cu–Zr-based bulk metallic glasses with large diameters of up to 1.5cm
    Scripta Materialia, 2006
    Co-Authors: Qingsheng Zhang, Wei Zhang, Akihisa Inoue
    Abstract:

    Cu–Zr-based bulk glassy alloys are synthesized with high glass-forming ability in a Cu42−xZr42+xAg8Al8 system by Copper Mold casting. Bulk glassy alloys with a diameter of 10 mm can be easily obtained in this alloy system. Also, 15-mm glassy alloy rods are formed for the Cu40Zr44Ag8Al8, Cu38Zr46Ag8Al8 and Cu36Zr48Ag8Al8 alloys by Copper Mold casting. These glassy alloys exhibit high fracture strengths of over 1850 MPa with Young’s moduli of about 115 GPa.

  • preparation and properties study of bulk fe75 5ga3p10 5c4b4si3 metallic glass ring by Copper Mold casting
    Intermetallics, 2004
    Co-Authors: Shyuesheng Wu, Baolong Shen, Akihisa Inoue
    Abstract:

    Abstract The bulk Fe75.5Ga3P10.5C4B4Si3 metallic glass ring with the outer diameter of 10 mm, the inner diameter of 6 mm and the thickness of 1 mm was successfully prepared by Copper Mold casting. The Curie temperature is 634 K, the glass transition temperature (Tg), the supercooled liquid region (ΔTx(=Tx−Tg)) and the saturation magnetization of the bulk metallic glass ring in as-made state were 634, 734, 40 K and 1.33 T. The associated activation energy of the bulk metallic glass ring was determined using differential scanning calorimetry and Kissinger's peak shift method. We hopefully can develop the bulk amorphous alloy into the application on a new type of magnetic cores.

  • preparation of the bulk fe al ga p c b si glassy alloys in a ringed form by Copper Mold casting
    Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2001
    Co-Authors: Kazuaki Ikarashi, A. Makino, Takao Mizushima, Akihisa Inoue
    Abstract:

    Abstract The bulk Fe–Al–Ga–P–C–B–Si glassy alloy in a ringed form with the outer diameter of 10 mm, the inner diameter of 6 mm and the thickness of 1 mm was prepared by Copper Mold casting. This bulk alloy sample was composed of a single amorphous phase and had a supercooled liquid region of 59 K, which was the same as that of the melt-spun ribbon. The saturation magnetization, the coercivity and the maximum permeability of the bulk amorphous alloy sample in as-made state were about 1.2 T, 2.2 A/m and 110 000, respectively. These good soft magnetic properties of the bulk sample depend upon its high structural homogeneity based on large glass forming ability. In addition, the core loss for the Fe-based bulk amorphous alloy is lower than that of a nonoriented 3.5% Si steel in as-made state at the frequency of 50–60 Hz. It is, therefore, concluded that the Fe–Al–Ga–P–C–B–Si glassy alloy will be one of the useful industrial materials.

  • soft magnetic properties of ring shape bulk glassy fe al ga p c b si alloy prepared by Copper Mold casting
    Materials Transactions Jim, 1999
    Co-Authors: Takao Mizushima, A. Makino, Kazuaki Ikarashi, Shoji Yoshida, Akihisa Inoue
    Abstract:

    Structural and soft magnetic properties were investigated for a bulk glassy Fe 70 Al 5 Ga 2 P 9.65 C 5.75 B 4.6 Si 3 alloy in a ring shape form with an outer diameter of 10 mm, an inner diameter of 6 mm and a thickness of I mm prepared by Copper Mold casting. The bulk sample composes of an amorphous single phase. The supercooled liquid region (Δ T x ) defined by the difference between the crystallization temperature (T x ) and glass transition temperature (T g ) for the bulk glassy alloy is about 60 K, being in agreement with that of the corresponding amorphous alloy ribbon. Saturation magnetization (σ s ) and Curie temperature (T c ) for the bulk sample are about 1.2 T and 620 K, respectively, both of which agree with those of the melt-spun ribbon. Furthermore, the maximum permeability (μ max ) and the coercivity (H c ) for the bulk glassy sample in as cast state are about 110000 and 2.2 A/m, respectively. These excellent soft magnetic properties are presumably due to a higher degree of structural homogeneity resulting from its high glass-forming ability. It is concluded that the good soft magnetic properties combined with high glass-forming-ability and castability of the Fe-Al-Ga-P-C-B-Si glassy alloy hold promise for its development as a future engineering magnetic material.

  • Correlation between internal states and plasticity in bulk metallic glass
    Applied Physics Letters, 2011
    Co-Authors: Y. Zhang, M Stoica, Uta Kühn, Caiju Li, Kaikai Song, J Eckert
    Abstract:

    We report a close correlation between the internal states and plasticity in a bulk metallic glass (BMG) and discover that the optimization of Copper-Mold casting current can induce large plasticity stably in an otherwise brittle BMG. It is possible to confirm that larger plasticity corresponds to the internal states with more average free volume (FV) as revealed by lower density, higher enthalpy change, and higher Poisson’s ratio. The enhanced plastic deformation mechanism is interpreted based on the FV model of BMGs, and our results may have some implications for understanding the role of the FV during plastic deformation of BMGs.We report a close correlation between the internal states and plasticity in a bulk metallic glass (BMG) and discover that the optimization of Copper-Mold casting current can induce large plasticity stably in an otherwise brittle BMG.

  • structure and mechanical properties of al mg alloys produced by Copper Mold casting
    Journal of Alloys and Compounds, 2010
    Co-Authors: Sergio Scudino, Miroslava Sakaliyska, Kumar Babu Surreddi, J Eckert
    Abstract:

    Abstract Al 100− x Mg x bulk samples with 5 ≤  x  ≤ 80 have been produced by Copper Mold casting. Casting has a remarkable effect on phase formation by suppressing the formation of the equilibrium β-Al 3 Mg 2 phase for 5 ≤  x  ≤ 10 and x  = 50. In addition, the solid solubility of Mg in Al can be extended from the equilibrium value of about 1 at.% Mg up to values exceeding 10 at.% Mg. Room temperature compression tests reveal interesting mechanical properties. For example, the samples with compositions in the range 5 ≤  x  ≤ 20 display high strength ranging from 375 to 650 MPa combined with a fracture strain in the range of 90–10%. These results indicate that Copper Mold casting is a suitable processing route for the production of Al–Mg alloys with promising mechanical properties.

    Co-Authors: M Stoica, J Eckert, Stefan Roth, L Schultz
    Abstract:

    The Fe77.5−x−y−zCrxMoyGazP12C5B5.5 bulk glassy alloy was prepared in the shape of rods and ribbons using Copper Mold casting and melt spinning, respectively. The structure was investigated by X-ray diffraction (XRD) and the thermal stability was checked by differential scanning calorimetry (DSC). It was found that the samples consist of an a single amorphous phase and exhibit a rather wide supercooled liquid region before crystallization. Some characteristic thermal properties of the amorphous samples as a function of the geometrical dimensions are discussed, as well as the dependence of the glass-forming ability on composition. Additionally, some magnetic data like coercivity Hc, saturation polarization Js and Curie temperature Tc are presented.
