Phase Constituents of Ti-Cr-Au and Ti-Cr-Au-Zr Alloy Systems
The phase constituents of the Ti-Cr-Au ternary and Ti-Cr-Au-Zr quaternary systems were investigated using X-ray diffraction analysis and optical microscopy. The composition ranges were 3~10mol%Cr and 0~8mol%Au for the ternary system, and 0~42mol%Zr were added to Ti-5mol%Cr-4mol%Au. It was found that the β phase was stabilized by the addition of Cr and Zr, and that A15-type Ti3Au was formed when the Au content was 6mol% or higher. Besides, C14 Laves phase similar to Zr33Ti40Au27 was recognized in Ti-5mol%Cr-4mol%Au-42mol%Zr.
