本文从冲击能量的分析角度出发,推导出材料断裂韧性与夏比V型缺口冲击能之间的普遍关系模型;在不同回火温度条件下,建立了PCrNi3Mo钢断裂韧性与冲击能之间的定量关系。
Based on the analysis of impact energy, this paper deduces the universal relation model between material fracture toughness and Charpy V-notch impact energy. Under different tempering temperatures, the quantitative relationship between fracture toughness and impact energy of PCrNi3Mo steel is established relationship.
