Improvement of Fracture Toughness in High Strength Beta Titanium Alloys.

Abstract

Specimens of beta titanium alloy, Ti-15-3, were heat treated to different strength levels by single-stage and multi-stage ageing, and hardness, tensile and fracture properties were determined to identify heat treatments well suited for structural applications. These studies were supplemented by microstructural analysis. Attractive combinations of strength and fracture toughness were obtained at medium to high strength levels. The relationship between microstructure and mechanical properties is discussed.
