Abstract
An exploratory survey of the heat treatment response of commercial titanium alloys (Ti-150A, RC-130B, and MST 3Al-5Cr alloys) shows a wide range of possible hardness and microstructural characteristics. The hardening is primarily dependent on the solid state transformation of the βphase. An age hardening reaction which apparently is associated with β decomposition and precipitation has been shown. Brittleness and notch sensitivity appear to be characteristic of age hardening to high hardness. Ductility, tensile strengths, and elongations are given.
