... the possibility of using heat treatment. Titanium is a transition metal with an incomplete d shell in its electronic structure, which enables it to form solid solutions with most substitutional elements having a size factor within ±20%. Alloying of titanium is dominated by the ability of elements to stabilize...

.... In this article, the discussion is limited to heat treatment of cast alloys. The choice of heat treatment depends on various factors, such as application, dimensional and microstructural stability, mechanical properties, sensitivity to environmental degradation, and so on. A typical heat treatment regimen...
