Abstract: The present study analyzes the possible impact temperature may have on slip behavior indicators through microscopic observation on stick-slip and stable-slip experimental samples at different temperatures. The results show that deformation changes with the rise in temperature according to certain rules. As for stick-slip samples, when temperature rises, deformation develops from brittle high-speed fracture into alternation of ductile-brittle slow and high speed stick-slip and offset. As for stable-slip samples, deformation develops from slow brittle deformation to slow ductile deformation.
