Aluminum Alloys for ALS Cryogenic Tanks: Oxygen Compatibility. Volume 2

Abstract

In part II of this program, selected tempers of alloys 8090, 2090, WL049, and 2219 were tested for compatibility with liquid oxygen in modified open-cup and pressurized mechanical-impact equipment at White Sands Test Facility. Drop height (potential energy), pressure, and environment (liquid oxygen, LOX, and gaseous oxygen, GOX were varied in these tests. Additional promoted-combustion tests were also conducted at WSTF. Reactions, ranging in size from those that could be observed with the naked eye to those that required use of the scanning electron microscope (SEM), were identified in all alloys. Those that require little or no magnifying power to view are labeled macroreactions; those that require the use of optical microscopy or SEM are called microreactions. Al-Li alloys had more macroreactions than 2219; 2219 had more, or an equivalent number of microreactions than each of the Al-Li alloys.
