The Role of Microstructure in Determining Fracture Toughness and Fatigue Properties of High Strength Titanium Alloys,

Abstract

High strength titanium alloys have found extensive application in critical aircraft components because of their high strength/density and generally good engineering properties. The ability to predict the response of the material to the growth of subcritical cracks is important because of the risk of catastrophic failures in aircraft. This review examines the general theory of fatigue and flaw growth and relates these to fracture mechanics parameters. A general review of the physical metallurgy of titanium alloys is presented with primary emphasis placed on Ti-6Al-4V and Ti-6Al-6V-2Sn. Emphasis is placed on the roles of microstructural, chemical, and textural variations in controlling the fracture toughness and fatigue crack growth rate. (Modified author abstract)
