Abstract

Boeing and Howmet conducted a joint program to evaluate the castability of titanium alloy 5533 (Ti-5Al-5V-5Mo-3Cr). In terms of castability, tests showed that Ti-5553 is comparable to Ti-6242 and Ti-15-3-3-3. Mechanical property evaluations showed that the alloy exhibit substantially superior strength and fatigue characteristics relative to other cast titanium alloys and more specifically Ti-6Al-4V alloy, which is the dominant casting alloy. It was observed that the ability to use controlled heat treatment parameters to produce Widmanstatten type structures is the key ingredient in obtaining superior tensile strength properties in the alloy.
