| Abstract Scope |
AISI M2 tool steel is widely used in cutting applications requiring high operating temperatures and long material life, such as heavy cutting and high-speed machining. The steel is typically alloyed with tungsten, molybdenum, chromium, and vanadium to enhance its properties. Binder jetting is a promising additive manufacturing technique capable of producing complex shapes with minimal residual stresses and isotropic properties. However, the processing-structure-property relationships of M2 tool steel produced via binder jetting remain largely unexplored. Therefore, this study aims to investigate the effects of printing parameters and sintering conditions on the microstructure and mechanical properties of binder jetted M2 tool steel. In this study, two powder sizes (~ 5 and 10 µm) were used, and sintering was performed at varying temperatures (1270, 1280, and 1300°C) and durations (60 and 120 minutes). Microstructure, mechanical, and wear properties of binder jet processed M2 tool steel will be discussed in the talk. |
