Eutectic nucleation in Al-25wt.% Si alloy through DSCWU Yuyinga, b, LIU Xiangfaa, JIANG Bingganga, and HUANG Chuanzhenb aKey Laboratory for Liquid-Solid Structural Evolution and Processing... nucleation in hypereutectic Al-25wt.%Si alloy with the addition of P was studied by calculating the activation energy and nucleation work. The results indicate that P refinement, which can decrease......
can play the role of heterogeneous nucleation. When the previous nucleation particles cannot provide enough supercooling for the next particle, the remaining heterogeneous nucleation particles cannot produce nucleation, and the heterogeneous nucleation process cannot continue. It is well known that during hot deformation, second phases of different sizes can promote or inhibit DRX behavior......
