THERMAL STABILITY OF NON-EQUILIBRIUS MICROSTRUCTURE IN MICROALLOYED STEEL DURING REHEATING S.W. Yang1,D. Tang2,H.B. Wu2,H.T. Jiang2,X.L. He1 (1.Dept. of Materials Physics, University of Science.... The sample relaxed for 60s displayed the highest thermo-stability, whereas microstructure evolution was the quickest in the sample relaxed for 1000s even though it was the softest prior to reheating......
REHEATING TEMPERATURE CONTRAST AND MICROSTRUCTURES OF 7075 A1 ALLOY CAST BY LIQUIDUS SEMI-CONTINUOUS CASTING G.M.Lu1,J.Dong1,J.Z.Cui1 (1.The Key Lab. of Electromagnetic Processing of Material, Ministry of Education, Northeastern University,Shenyang 110004, China) Abstract:In this study, reheating of liquidus semi-continuous east billets of 7075 Al alloy wascarried out in a resistance furnace......
provided with rheocasting and extruding/extending forming by shearing-cooling-rolling(SCR) technology during reheating in semi-solid state was investigated. The microstructural differences and their generation causes for both billets were also analyzed. The results show that during reheating, the grains of rheocasting billets grow up and spheroidize gradually with the prolongation of isothermal......
