金属材料在热形变过程中可能会发生动态回复、动态再结晶、动态沉淀、静态回复、静态再结晶、静态沉淀、亚动态再结晶和应变诱导沉淀等显微组织的变化。本文综述了一种依据热流变曲线测定这些组织变化的试验方法。该方法不但能测定各种回复、再结晶和沉淀过程的动力学,而且能揭示它们之间的交互作用。由于该方法能直接对热形变高温状态进行测定,因而消除了淬火后通常在室温下间接测定所带来的试验误差。 Metallic materials may undergo dynamic recovery, dynamic recrystallization, dynamic precipitation, static recovery, static recrystallization, static precipitation, sub-dynamic recrystallization and strain induced precipitation in the thermal deformation process. This article reviews a test method for determining these tissue changes based on the thermoforming curve. This method can not only determine the kinetics of various recovery, recrystallization and precipitation processes, but also reveal the interaction between them. Because this method can directly measure the hot deformation temperature, thus eliminating the test error usually caused by indirect measurement at room temperature after quenching.
