Residual Stresses,Stress Relief,and Annealing of Titanium and Titanium Alloys.

摘要

The report discusses both theory and practice related to the occurrence and elimination of residual stresses in titanium and its alloys. Following a brief section on the general principles of heat treatment of titanium alloys, a description of the origin and effects of residual stresses due to forming,specifically,of the Bauschinger Effect,is presented. Additional data covers residual stresses due to mechanical operations such as grinding,shot peening,grit blasting,vibratory tumbling,and joining. Methods of treatment to eliminate residual stresses are described. (Author)
