High Temperature Properties of Alloys Being Considered for Design of a Concentric Canister Launcher

Abstract

This report describes a study to determine the high temperature mechanical properties of several titanium alloys and to compare them with properties of AISI 316L stainless steel and ASTM A387 structural steel. The steel materials are less costly to procure but exhibit good resistance to corrosion in seawater environments. Six titanium alloys were evaluated as candidate materials for use in a Concentric Canister Launcher (CCL). Each titanium alloy was tested at three temperatures (68 deg F, 2000 deg F, and 2400 deg F). Strain-rate change tests were used to determine the strain rate sensitivity of the alloys at each test temperature. Optical metallography was performed on two of the alloys to determine the relationship between test temperature and microstructure (presence of second phase precipitates, grain size). Complete test results are included, along with figures and tables of test data.
