microstructure and mechanical properties of rheo Squeeze Casting az91 ca magnesium alloy prepared by gas bubbling process
Materials & Design, 2015Co-Authors: Yang Zhang, Guohua Wu, Liang Zhang, Song Pang, Wenjiang DingAbstract:Abstract Rheo-Squeeze Casting combined with gas bubbling process was proved effective to improve the mechanical properties of AZ91-2 wt%Ca (AZX912) alloy. Increase of gas flow led to improvement of the quality of AZX912 semi-solid slurry and improved ductility of rheo-Squeeze Casting AZX912 alloy samples. Increase of applied pressure brought refinement in as-cast microstructure and reduction of porosity, as well as continuous improvement in both tensile strength and elongation. Heat treatment at 410 °C promoted dissolution of β-Mg 17 Al 12 phase, morphology modification of Al 2 Ca phase and further increase of both tensile strength and ductility. Compared with conventional Squeeze Casting, the mechanical properties of rheo-Squeeze Casting AZX912 alloy were improved by more than 20%. The improvement in mechanical properties was mainly attributed to the grain refinement in microstructure.

effects of processing parameters and ca content on microstructure and mechanical properties of Squeeze Casting az91 ca alloys
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2014Co-Authors: Yang Zhang, Liang Zhang, Song Pang, Wencai Liu, Yingdong Wang, Wenjiang DingAbstract:Abstract AZ91–(1–3 wt%) Ca alloys were prepared by direct Squeeze Casting, in which the melt was solidified under applied pressure. The effects of processing parameters (such as applied pressure and pouring temperature) and Ca content on microstructure and mechanical properties of Squeeze Casting AZ91–Ca alloys were investigated. The results indicate that the microstructure was refined with the increase of applied pressure, and the mechanical properties were improved. When the pouring temperature was lowered down to near the liquidus, the microstructure was further refined and α-Mg grains turned rosette-like. The negative effect on ambient temperature mechanical properties caused by the addition of Ca into AZ91 alloy was inhibited by Squeeze Casting. Compared to conventional Casting, Squeeze Casting process can offer AZ91–Ca alloys better mechanical properties, especially in elongation to failure (Ef).

thermal fluid solidification analysis of automobile part by horizontal Squeeze Casting process and experimental evaluation
Journal of Materials Processing Technology, 2004Co-Authors: S.w. Youn, C G KangAbstract:Abstract The Squeeze Casting process of molten metal is very attractive for producing near net shape components with an arbitrary complicated shape. It is particularly attractive for processing engine mounting brackets with high strength at desired elongation and hardness, since the porosity of dispersed defects under the action of the pressure is remarkably reduced during Squeeze Casting. Therefore, to develop suspension parts, such as the knuckle, arm, and structure parts to support the automobile engine, the Squeeze Casting process was developed with die design and process parameter control.

Microstructure and Mechanical Properties of $SiC_p/6061$ Al Composites Fabricated by Indirect Squeeze Casting
Journal of Korea Foundry Society, 1998Co-Authors: C G KangAbstract:Particulate reinforced aluminum alloys produced by indirect Squeeze Casting are difficult to shape by cutting or milling. Therefore near net shape forming of complex shapes is of high economic and technical interest. The complex shape products of Al composites are fabricated by the melt-stirring and indirect Squeeze Casting process. The mold temperatures are and and applied pressures are 70, 100, and 130 MPa. The volume fractions of the reinforcements are in the range of 5 vol% to 15 vol%. The reinforcement dispersion state are observed using on optical microscope. By employing observed results systematically a correlation is demonstrated among the microstructure, particles behavior, mechanical properties and processing parameters for an optimum melt-stirring(compoCasting) and indirect Squeeze Casting process of MMCs. A procedure to establish the optimum Squeeze Casting of Al-MMCs is proposed.
