Abstract Scope |
In spite of major progress in additive manufacturing (AM), the high solidification rates and temperature gradient impose restrictions on the alloys that can be successfully processed without cracks and voids. Thus, many conventional high-performance alloys cannot be fabricated defect-free using AM. We use CALPHAD to rapidly screen through alloy additions without imposing large changes on conventional alloy compositions. The rationale is that such an approach may not require a large matrix of testing for insertion into actual applications. Examples include high-strength Al-alloys as well as Ni-base superalloys for high temperature applications. We will detail our rapid screening methodology and the use of experimental technique to the simulate rapid solidification conditions of AM, prior to fabrication of new alloy powders. Comparisons of theoretical results with experimental data will be provided. |
