T-122 Introduction

Tantalum tungsten hafnium alloy is made by adding certain amount of tungsten and hafnium in the base of tantalum. In the temperature range of 93-1426˚C, tantalum tungsten hafnium alloy has excellent thermal stability and high creep strength. From 1960 to 1963, the United States sucessfully developed Ta10W - 2.5 Hf - 0.01Zr-0.1Nb - 0.02Mo alloy. Tantalum tungsten hafnium alloy is divided into solid - soluble strengthening alloy and dispersion strengthened alloy by reinforcement schedule.
