Abstract

Rapid solidification techniques are fundamental for developing advanced materials with unique microstructures and properties. This research highlights the impact of ultra-high cooling rates on the formation of novel phases and enhanced mechanical characteristics in various metallic alloys, including Al-Mg-Si, Zr-based bulk metallic glasses, NiAl intermetallics, high-strength steels, and refractory high-entropy alloys. The process is crucial for controlling precipitation hardening in Al-Cu alloys, influencing powder characteristics for additive manufacturing, and affecting the structural stability of Fe-based nanoparticles. Furthermore, it aids in achieving homogeneous microstructures in Ni-based superalloys by suppressing segregation and is key to forming metastable phases in Ti-Al alloys. These findings underscore the versatility of rapid solidification in tailoring material performance for demanding applications
