According to the results of simulation of stressed states, it is shown that coarse graphite inclusions formed in the walls of case-shaped parts of transient in thickness are the sites of initiation of defects due to the changes in the dislocation structure and diffusion of carbon from graphite. The cavities formed in graphite also promote the development of oxidation.

应力对灰铸铁结构变化的影响

应力状态模拟结果表明，由于位错结构的变化和碳的扩散，在厚度瞬变的壳形件壁上形成的粗大石墨夹杂物是缺陷的萌生部位。石墨。石墨中形成的空穴也促进了氧化的发展。
