The Thermomechanical Stability of Tungsten Alloys for Restart Applications.

Abstract

The structural behavior of tungsten and tungsten alloys in a cyclic heating environment closely resembling the thermal environment of a restartable rocket motor has been investigated in a combined laboratory and analytical study. The purpose was to achieve a better understanding of the factors affecting the deformation behavior and dimensional stability of rocket nozzle components. An important accomplishment of this program was the development and demonstration of an analytical approach capable of synthesizing the many material and environmental variables and which has potential for a wide range of laboratory and rocket hardware applications.
