Advanced Processing of a Near Beta Titanium Alloy

点击翻译按钮获取中文摘要

Titanium alloys have been widely used in the aerospace, chemical, and biomedical industries due to their high specific strength and excellent corrosion resistance. For the next generation of lighter and energy-efficient aircraft structures, the use of high strength near-β Ti-alloys in the fuselage, bogie beam, flap track, nacelles, pylon, and la195nding gear assemblies will be cost effective from the perspective of weight reduction and mechanical properties compared to the industry workhorse Ti-6Al-4V, the most widely used α+β alloy. Major aerospace manufacturers like Airbus and Boeing have started to use forged near-β Ti-alloys as landing gear components. It is expected that near-β Ti-alloys will gain wider applications in the future. However, while significant research has been conducted on near-β Ti-alloy design, little work has been done to understand the microstructure-mechanical properties correlations from the industrial manufacturing point of view, especially during processes such as, welding, forming, and additive manufacturing (AM).
