Mechanics of Ti-Ni BMG-Based Alloys: Experimental Study
Publication: Journal of Engineering Mechanics
Volume 140, Issue 1
Abstract
Titanium-nickel (Ti-Ni)–based bulk metallic glass (BMG) alloys were prepared by centrifugal casting into a copper mold. The effect of five rolled temperatures, namely, room temperature and 200, 300, 400, and 500°C, on the behavior of amorphous BMG, the microstructural features, and the mechanical properties were investigated. High-resolution scanning electron microscopy (HRSEM) reveals the formation of nanoparticles in the amorphous alloys. The ultimate compressive stress of the rods rolled at 300°C was found to be the highest, whereas that of the rods rolled at 500°C was the lowest. The fracture strain for the rods rolled at 500°C was found to be the highest, which reflects the roughness of the fracture surface and the strength and integrity of the internal structure.
