Preheating Influence on the Precipitation Microstructure, Mechanical and Corrosive Properties of Additively Built Al-Cu-Li Alloy Contrasted with Conventional (T83) Alloy

In this paper, the high strength and lightweight Al-Cu-Li alloy (AA2099) is considered in as-built and preheated conditions (440 °C, 460 °C, 480 °C, 500 °C, and 520 °C). The purpose of this study is to investigate the influence of laser powder bed fusion (LPBF) in situ preheating on precipitation mi...
