TITANIUM-ALLOY DEVELOPMENT

The purpose of this paper is twofold:

1. 1.
   To review the metallurgical principles governing the development of titanium alloys.
2. 2.
   To present some preliminary results of work in progress at Armour on the development of titanium alloys for use at elevated temperatures.

To develop superior alloys requires, the authors say, an intelligent and systematic approach based on the following:

1. 1.
   Knowledge of the equilibrium phase relationships of titanium with other metals.
2. 2.
   Information regarding the kinetics of reactions in the solid state.

Use of this approach has, they add, resulted in the development of titanium-base alloys having excellent properties at temperatures up to 1020 F.
