摘　　要：研究ZG400在退火热处理时网格状珠光体组织的形成条件,分析了该组织与ZG400力学性能之间的关系。结果表明,当退火温度在900℃时珠光体呈明显的网格状分布,而在800、850和950℃温度下退火处理时并没发现这种组织。网格状珠光体的出现使ZG400的屈服强度、抗拉强度、冲击韧度和疲劳性能降低,但并未对其塑性产生明显影响。The forming conditions of grid pearlitic structure in ZG400 during annealing were studied, and the relationship of grid pearlitic structure and mechanical properties were analyzed. The results show that grid pearlitic structure can be found when annealing at 900 ℃, and do not find this structure at 800, 850 and 950 ℃. The yield strength, tensile strength, impact toughness and fatigue resistance of ZG400 are reduced for grid pearlitic structure, but not obvious influence on the plastic.
