Grain refinement of AZ31 magnesium alloy by Al-Ti-C-Y master alloy许春香,卢斌峰,吕正玲,梁伟摘 要:Al-Ti-C-Y master alloy was prepared by combining SHS technique and melting-casting method. The microstructure of master alloy and its grain-refining effect on AZ31 alloy were investigated by means of OM, XRD, SEM and EDS. Experimental results indicated that the prepared......

Trans. Nonferrous Met. Soc. China 20(2010) s906-s910 Rheological behavior, microstructure and hardness of A356 aluminum alloy in semisolid state using backward extrusion process S... alloy in the semi-solid state was investigated using backward extrusion process. Experiments were performed at 5 temperatures and 4 different wall thicknesses. Viscosities were determined using the force......
Taper barrel rheomoulding process for semi-solid slurry preparation and microstructure evolution of A356 aluminum alloy ZHANG Fan(张 帆), KANG Yong-lin(康永林), YANG Liu-qing(杨柳青), DING Rui-hua(丁瑞华... rheomoulding (TBR) machine for light alloy semi-solid slurry preparation was introduced. The semi-solid slurry was obtained from the intense shearing turbulence of the alloy melt in the cause......
