Abstract
The objective of this study is to investigate the effects of solid-state phase transformation on welding residual stress and distortion in low carbon and medium carbon steels. In this study, based on ABAQUS code, a sequentially coupled thermal, metallurgical, mechanical 3-D finite element model is developed. In the numerical simulations, different continuous cooling transformation diagrams are used to predict the fractions of martensite for the fusion zone, the coarse-grained HAZ and the fine-grained HAZ, respectively. Effects of volume change due to austenite–martensite transformation on the final residual stress and the welding distortion are examined. The simulation results revealed that the final residual stress and the welding distortion in low carbon steel do not seem to be influenced by the solid-state phase transformation. However, for the medium carbon steel, the final residual stresses and the welding distortion seem to be significantly affected by the martensitic transformation.
期刊介绍：
Materials and Design is a multidisciplinary journal that publishes original research reports, review articles, and express communications. It covers a wide range of topics including the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, as well as the design of materials and engineering systems, and their applications in technology.
The journal aims to integrate various disciplines such as materials science, engineering, physics, and chemistry. By exploring themes from materials to design, it seeks to uncover connections between natural and artificial materials, and between experimental findings and theoretical models. Manuscripts submitted to Materials and Design are expected to offer elements of discovery and surprise, contributing to new insights into the architecture and function of matter.
