thermal expansion studies on a metallic glass ribbon reinforced glass ceramic Matrix Composite
Journal of Materials Science, 1994Co-Authors: Rajendra U. Vaidya, Krishan Kumar Chawla, K. N. SubramanianAbstract:The thermal-expansion behaviour of a metallic-glass ribbon-reinforced glass-ceramic-Matrix Composite was studied. The coefficient of thermal expansion of such Composites measured in the longitudinal direction was correlated with the volume fraction, the length and the width of the ribbon reinforcements. The experimentally measured values of the thermal-expansion coefficients were found to be in good agreement with a modified Schapery's equation.

Interfacial effects in a metallic-glass ribbon reinforced glass-ceramic Matrix Composite
Journal of Materials Science, 1992Co-Authors: Rajendra U. Vaidya, C. Norris, K. N. SubramanianAbstract:The effect of temperature on the interfacial effects in a metallic-glass ribbon reinforced glass-ceramic Matrix Composite was investigated. The metallic-glass ribbon present in this Composite was found to be significantly affected at elevated temperatures, owing to the diffusion of lead and zinc from the Matrix. The presence of the Matrix in the vicinity of the ribbon enhanced the formation of an oxide layer on the ribbon surface. The oxide layer decreased the interfacial bond strength between the ribbon and the Matrix, affecting the failure mode of such Composites at elevated temperatures.

A magnesium alloy Matrix Composite reinforced with metallic glas
Composites Science and Technology, 2009Co-Authors: Dina V. Dudina, Alain Le Moulec, M. Aljerf, Alain Reza Yavari, Konstantinos Georgarakis, Y X Li, Atsushi InoueAbstract:Novel light-weight materials of advanced performance are now experiencing global interest due to the strong need to reduce energy consumption in land and air transportation sectors. Here we report on a novel magnesium alloy Matrix Composite material. The reinforcing phase in the magnesium alloy is a fine dispersion of metallic glass particles. The Composite is sintered from the powder mixture of the alloy and metallic glass at a temperature slightly above the glass transition T-g of the metallic glass particles that is close to the Mg alloy's solidus temperature. At the compaction temperature, the metallic glass acts as a soft liquid-like binder but upon cooling it becomes the hard reinforcement component of the Composite. Processing, microstructure and mechanical properties of the Composite are discussed.

an investigation of the sliding wear behavior of cu Matrix Composite reinforced by carbon nanotubes
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2001Co-Authors: Shurong Dong, Xiaobin ZhangAbstract:Abstract The friction and wear behavior of Cu-Matrix Composite reinforced by carbon nanotubes (Nanotube/Cu Composite) were investigated. By scanning electron microscopy (SEM) and X-ray diffraction (XRD), the worn surfaces and the worn chips were analyzed. The volume fraction of nanotubes is a main factor for the decrease of the wear rate of The Nanotube/Cu Composite, which is associated with carbon nanotubes forming a protective oxide film on the sliding surface of the specimen. The optimum nanotubes content is 12–15%. Both the coefficients of friction and weight loss of the Nanotube/Cu Composite are lower than those for Cu-Matrix Composite reinforced by carbon fiber (CF/Cu) owing to the much high intensity of nanotube.

Characteristics Study of Physical, Mechanical and Tribological Behaviour of SiC/TiB_2 Dispersed Aluminium Matrix Composite
Silicon, 2021Co-Authors: Abhijit Bhowmik, Dipankar Dey, Ajay BiswasAbstract:SiC and TiB_2 particle reinforced Al7075 Matrix Composite has numerous applications such as aircraft structures, mould tool manufacturing, and structural application due to less weight to strength ratio, low wear rate and high creeping behaviour. This paper deals with the various effect of the physical properties, mechanical properties, microstructure evaluation, and wear resistance of SiC, and TiB_2 particulates reinforced Al7075 Matrix Composite fabricated by stir casting. XRD revealed the proper dispersion of SiC and TiB_2 reinforcement throughout the aluminium Matrix without the formation of an intermetallic compound. Ultimate tensile strength (UTS) and microhardness of aluminium Matrix Composite developed its strength and hardness from 140 MPa to 198 MPa and 66 HV to 86 HV respectively with the incorporation of SiC and TiB_2 reinforcement. As compared to unreinforced aluminium Matrix 7075, the ultimate tensile strength of SiC and TiB_2 reinforced Composite significantly developed due to better bonding and clear interface of reinforced particulates. Microstructure analyses that SiC and TiB_2 contents homogeneously dispersed throughout the aluminium Matrix. The unlubricated pin on disc tribotest was performed to determine the wear rate of casted aluminium Matrix Composite. The wear tests were performed at various loads (10, 20, 30 and 40 N), sliding velocity (1.25, 2.5, 3.75 and 5 m/s) and covering distance (1000, 2000, 3000 and 4000 m) which rotates against counter plate EN31 steel disc.

Comparative Study of Microstructure, Physical and Mechanical Characterization of SiC/TiB_2 Reinforced Aluminium Matrix Composite
Silicon, 2020Co-Authors: Abhijit Bhowmik, Dipankar Dey, Ajay BiswasAbstract:Aluminium Matrix Composites impact greatly in modern trends for huge applications in the aerospace and automotive industry due to its better strength to weight ratio and temperature resistance capacity. This work investigated the effect on SiC and TiB_2 powder reinforced aluminium Matrix Composite fabricated by stir casting. Stir casting is a widely used liquid state method of a fabrication technique for preparing metal Matrix Composite with the help of mechanical stirring. Density, tensile strength, hardness, and fracture analysis were done to observe the development of ceramic particle reinforced aluminium Matrix Composite. SEM analysis revealed the uniform distribution of reinforcement particles throughout the aluminium Matrix. Universal tensile strength and micro hardness of aluminium Matrix Composite enhanced from 140 MPa to 182 MPa and 66 HV to 81 HV respectively due to the addition of particle reinforcement. The microstructural investigation from the fractured surface of tensile samples indicated ductile nature appeared in Al7075, Al7075/SiC, and Al7075/TiB_2 Composites due to nucleation and micro-voids formation.
