Mechanical Behavior of Titanium Alloys (The Influence of Alpha/Beta Interface Phase on Tensile Properties in Ti-6Al-4V).

Abstract

The effects of alpha/beta interface phase on room temperature tensile properties in Ti-6Al-4V having an equiaxed primary alpha microstructure have been studied systematically. Due to conditions under which it grows, manipulation of interface phase width results in alteration of the volume fraction of primary alpha in the alloy. Tensile yield strength and elongation were correlated to interface phase width and volume fraction primary alpha. The relative individual influence of each of these microstructural features on properties is not unambiguously clear, but evidence indicates that yield strength increases with increasing interface phase width when the interface phase exceeds about 2500 angstrom and elongation decreases with increasing interface phase width when the interface phase is less than about 2500 angstrom.
