The important characteristics of this alloy are associated with its all- beta structure and the decomposition of that structure during heat treatment. In the annealed condition, it is a medium-strength very formable alloy. It can be hardened by an aging treatment to have yield strengths in excess of 180,000 psi. With its density of 0.174 pound per cubic inch, the alloy is capable of a strength-weight ratio of over 1,000,000 psi per cubic inch. The response of the ailoy to heat treatment is dependent on the processing history of the material. Combinations of cold or warm working followed by aging produce higher strengths than are obtained by aging alone. Aging treatments should be adjusted to compensate for the cold or warm working. The alloy is weldable, and the strength and ductility of welds are comparable to the strength and ductility of the annealed material. Heat treatment of welds will produce properties similar to those obtained in the base metal. However, since the welding cycle destroys the effect of processing history, the influence of cold or warm working on subsequent aged properties is not obtained. Considerable research is being conducted on the heat treatment of welds and welded assemblies. Detailed data on the heat treatment, ical properties, welding, and forming of the allbeta alloy are given. (auth)
