Modeling microstructure development in weld materials

PDF Version Also Available for Download.

Description

Microstructure development in the weld metal region is controlled by various physical processes such as thermochemical reactions in liquid, solidification, and solid state transformations. There is a need for fundamental and generalized models that can predict the effect of these physical processes on microstructure development in a wide variety of alloy systems during welding processes. This paper describes certain advances made in the area of modeling the microstructure development in low-alloy steel, stainless steel, and Ni-base superalloy. In addition, this paper describes the importance of advanced analytical techniques for fundamental understanding of phase transformation mechanisms in welds.
