Africa Received 13 May 2010; accepted 25 June 2010 Abstract: Since the automotive industry has many possible applications for semi-solid metal (SSM)-high-pressure die casting (HPDC) parts, the newly... be obtained for SSM-HPDC A356 brake calipers are compared with those manufactured by gravity die casting. Results indicate that the differences in microstructures (globular or dendritic) do not have......
; 文章编号:1672-7207(2018)03-0544-09 Optimum design of die profile based on mixed wear model XU Wujiao, LIU Chengshang, MA Xin, GUO Ziqian, CHEN Fei (College of Material Science and Engineering, Chongqing University, Chongqing 400044, China) Abstract: Aiming at solving problems of great wearing and low life of mold, the optimum design of die profile based on mixed wear models was used. As an example......

Trans. Nonferrous Met. Soc. China 20(2010) s837-s841 Influence of surface liquid segregation on corrosion behavior of semi?solid metal high pressure die cast aluminium alloys E. P... shown by the authors that a surface liquid segregation (SLS) phenomenon existed in SSM-HPDC (high pressure die cast) plates of A356/7[8] and A201 casting alloys[9] and 2024, 6082 and 7075 wrought......
-assisted extrusion(IEDGE)) of the hollow back-typed section profile’s melt flow field inside and outside the die were numerically simulated. The die swell ratio, pressure, velocity, shear rate and normal stress field distributions of four extrusion methods were obtained. The results show that the phenomenon of die swell and shrink are easily generated due to the non-uniformed distribution......
