触变性

• When it was soaked in the semi - solid temperature , the preformed texture was accompanied with the part high - energy - area melting . its presentations were the honey combs at the grain boundary and the pools in the grain . it was the essence condition that the semi - solid metal maintained the solid character and had the thixotropy
  5 、形变组织半固态保温过程中伴随着局部高能区的熔化，表现为晶界蜂巢状结构和晶内液池现象，这是半固态合金保持固相特征并具有触变性的基本条件。
