| Abstract Scope |
Tungsten alloys have many potential ultra-high-temperature applications. However, due to the high melting and the ductile-to-brittle-transition temperature, tungsten alloys usually have low manufacturability, limiting their applications. This work proposes a new concept to advance BJAM (Binder Jet Additive Manufacturing) technology for tungsten alloy (pure tungsten with alloy binder) with high mechanical performance. To facilitate the sintering process, a new refractory alloy binder is designed for printing and sintering using the CALPHAD-based ICME (CALPHAD: Calculation of Phase Diagrams, ICME: Integrated Computational Materials Engineering) modeling. With the achievements of higher density, yield, and ultimate tensile strength and ductility than existing tungsten alloys made by additive manufacturing, this work approves the possibility of utilizing the BJAM technique to reach the target properties and complicated designs. |
