Effects of cold rolling on precipitates in inconel 718 alloy

Effects of cold rolling on precipitates in inconel 718 alloy The morphology, microstructure, and the volume fractions of γ″ phase and δ phase that occur during cold rolling and double aging of Inconel 718 alloy were investigated. Two treatments were developed to produce either single-pass cold rolling or double-pass cold rolling. Cold rolling not only induced the γ″ phase precipitation, but also prompted the γ″→δ phase transformation. Double-pass cold rolling enhanced the δ phase volume fraction, but decreased the γ″ phase volume fraction. The dimension of γ″ particle decreased as cold rolling reduction increased. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Materials Engineering and Performance Springer Journals

Abstract

The morphology, microstructure, and the volume fractions of γ″ phase and δ phase that occur during cold rolling and double aging of Inconel 718 alloy were investigated. Two treatments were developed to produce either single-pass cold rolling or double-pass cold rolling. Cold rolling not only induced the γ″ phase precipitation, but also prompted the γ″→δ phase transformation. Double-pass cold rolling enhanced the δ phase volume fraction, but decreased the γ″ phase volume fraction. The dimension of γ″ particle decreased as cold rolling reduction increased.
