Residual tensile stress can lessen the p a r t ' s fatigue life during its intended use and, if severe enough, can cause it to crack immediately. If cracking or microcracking are not present, residual stress can be alleviated by a post-grinding tempering operation. Residual stress cannot be seen by the naked eye, but detection is possible with
