Mechanical Properties and Castings Reaction Layer of Trial Titanium Alloy Containing Ag

Abstract

We measured the mechanical properties and thicknesses of the castings reaction layers of three experimental titanium alloys (Ti-9.4Ag-9.2Cu alloy, Ti-14.2Ag-9.6Zr alloy and Ti-14.3Ag-9.7Cr alloy) produced by levitation melting. Tensile strength, elongation and Vickers hardness were measured. As a result, the tensile strength of the Ti-9.4Ag-9.2Cu alloy was 781MPa. The Ti-14.2Ag-9.6Zr alloy, which was mixed with silver and zirconium, showed an elongation of 14.4% and Vickers hardness of Hv 257. The thickness of the castings reaction layer of each experimental titanium alloy casting was lower when compared with pure titanium castings.
