    Abstract

    The status of net-shape technologies in the titanium industry is reviewed in this paper including powder metallurgy, casting, and isothermal precision forging. Although titanium and its alloys are a design choice for many industrial and aerospace applications, use is still limited because of the relative high component cost, the result of high material processing, and machining costs. Net-shape technologies are an attractive avenue for reducing the cost without sacrificing properties and reliability. The three approaches to titanium net-shape technology offer a range of shape and property combinations. Titanium casting and isothermal precision forging are already an industrial reality and powder metallurgy is rapidly reaching such a position. The isothermal precision forging and powder metallurgy net-shape approaches not only offer lower cost and reduced material use, but also provide some mechanical properties superior to conventional products because of microstructural homogeneity and refinement.
