Trans. Nonferrous Met. Soc. China 25(2015) 3189-3196 Effects of cooling rate on solution heat treatment of as-cast A356 alloy Chang-lin YANG, Yuan-bing LI, Bo DANG, He-bin , Feng LIU State Key... of the solidification process on the following solution heat treatment of A356 alloy was investigated, where the cooling rates of 96 K/s and 3 K/s were obtained by the step-like metal mold. Then the eutectic silicon......
in %) alloy by the cyclic heat treatments was studied. The heat treatment scheme included a tempering at 1250°C and cyclic tempering at 1000 and 1200°C three times after solution treatment at the temperature above α phase transus followed by immediate fan cooling. The fine and homogeneous near-γ microstructure can be obtained by this heat treatment, which causes the breakdown of as-cast......
