microstructure of ADC12 aluminum alloy containing spherical solid particles was studied. A new strain-induced melt activation (SIMA) process was proposed. In the treatment, chips were cut from ADC12... aluminum alloy can be applied to semi-solid processing with the new SIMA method. Key words: ADC12 aluminum alloy; semi-solid; microstructure; strain-induced melt activation 1 Introduction The semi......

After pyrolysis and sintering, Al melt was infiltrated into the porous preforms, leading to the formation of Ti3AlC2-Al2O3-TiAl3 composite......
Calculation of cooling rate of amorphous aluminum alloy melt-spun ribbons HE Shi-wen (何世文), LIU Yong(刘 咏), LIU Zu-ming(刘祖铭), HUANG Bai-yun(黄伯云) State Key Laboratory of Powder Metallurgy... the cooling rates of aluminum amorphous ribbons. According to the above theoretical model, the critical cooling rate of aluminum amorphous ribbons by melt spinning is above 106 K/s, which proves......
J. Cent. South Univ. Technol. (2011) 18: 1726-1732 DOI: 10.1007/s11771-011-0894-0 Numerical simulation on melt flow with bubble stirring and temperature field in aluminum holding furnace ZHANG... on melt flow driven by porous plug bubbles in aluminum casting furnace. However, from the view of modeling, it can be seen as a bubble column flow. In the present study, Euler- Lagrange, more accurate......
