Grain Stability and Homogeneity in Mechanical Properties during Solid State Additive Manufacturing: A Review

Abstract

The ability to create complex components with improved mechanical qualities has drawn a lot of interest to solid state additive manufacturing (AM) techniques in recent years. Assuring uniformity in mechanical characteristics and grain stability, however, continues to be a significant problem in these procedures. The state-of-the-art techniques, developments, and difficulties related to grain stability and homogeneity in mechanical characteristics during solid state AM are critically examined in this review. The review begins by going over the basic ideas that underpin solid state AM processes and how they affect the creation of grain structures. It then delves into a number of variables that affect the homogeneity of mechanical properties and grain stability, including as process parameters, material characteristics, post-processing methods, and mechanisms of microstructural evolution. It also emphasises new advances in process control and monitoring techniques meant to improve grain stability and uniformity of mechanical characteristics. Insights into computer modelling techniques used to forecast grain growth and mechanical behaviour during solid state AM are also provided by this paper. The paper ends with possible pathways for future research and ways to overcome current obstacles to improve grain stability and mechanical property homogeneity, thus enhancing the promise of solid-state additive manufacturing technology.
