High Toughness Titanium Alloy Development.
Abstract
This is the final engineering report for a Naval Air Systems Command sponsored program to develop new titanium alloys for aircraft applications. During the first of the two phases in this effort, four thermomechanical processing/final heat treatment sequences were evaluated for each alloy. Evaluations at the conclusion of this phase revealed that mechanical properties of three of the four process conditions investigated for Ti-5Mo-4.5Al-1.5Cr met or exceeded the high toughness/moderate strength goal, indicating good reproducibility of these properties over a wide range of processing conditions. On the other hand, mechanical properties of the alloy designed to meet the moderate toughness goal at high strength levels, Ti-8Mo-2.5Al-4.5Cr, fell short of those goals. Because of a real need to develop an alloy of this type, particularly for forging applications, the second phase of this effort was concentrated on further development of this latter alloy.
