چکیده انگلیسی
The deformation and damage behaviors of commercially pure zinc were investigated under compression and cyclic compression-compression loadings. After the tests above, the surface deformation morphologies and fatigue crack initiation of all the deformed samples were carefully observed by optical microscope (OM) and scanning electron microscope (SEM). Compressive tests on the commercially pure zinc indicated that the deformation and damage mechanisms are slightly different from those under cyclic compression-compression loading. The main deformation and damage mechanisms consist of slipping, twinning, secondary twinning, kinking, cracking along grain boundary and twin boundary under different loadings. Based on the experimental results, the compressive and fatigue damage mechanisms were discussed.
