Hot isostatic pressing of nanostructured γ-TiAI powders

A study of the hot isostatic pressing (HIP’ing) of γ-TiAl powders produced by mechanical alloying, has demonstrated that full density can be achieved 400°C or more below the temperature required for conventional powder; that is 725°C or below. Nanostructured grains (≤ 100 nm) are observed after HIP’ing up to 850°C.     

Cost-affordable titanium: The component fabrication perspective

Titanium is the material of choice for a wide variety of applications. However, because of its relatively high price—a result of extraction and processing costs—it is used only when it is the only choice. This paper will overview the potential areas that are amenable to cost reduction for titanium products, emphasizing all steps in component fabrication from extraction and processing to the fabrication of final parts.
