Modelling the effects of phase transformations on welding stress and distortion

Research output: Chapter in Book/Report/Conference proceeding › Chapter

Abstract

Solid-state phase transformations can have dramatic effects on the residual stress distributions that exist in and around welds. In this chapter, the nature of some phase transformations in steels is described and the implications that each type has for the development of stress are discussed. The significance of the transformation-start temperature and the potential for its exploitation to mitigate weld residual stresses and distortion are explored, with the focus being placed on strategies for incorporating transformation effects into models for residual stress development. Finally, some challenges and priorities for future work in this area are described. © 2011 Woodhead Publishing Limited. All rights reserved.
