由于无析出区(PFZ)对应力腐蚀和机械性能会产生有害的影响,一些研究者对沉淀硬化型合金中的无析出区作了研究。早期的研究者都认为,无析出区的形成是由于在晶粒边界析
Because of the detrimental impact of PFZ on stress corrosion and mechanical properties, some researchers have studied precipitation-free areas in precipitation hardened alloys. Early researchers agree that the formation of non-precipitated areas is due to grain boundary analysis
