Abstract:

The objective of this task is to compile a list of materials testing capabilities suitable for testing the materials development for liquid rocket engines by the JANNAF liquid propulsion community in USA. Information has been collected on the materials testing capabilities in some of the commercial testing laboratories, academic research and development institutes, and government organizations it has been compiled, and has been listed in Tables I, II and III, respectively. The ASTM standards for most of the materials properties testing have been listed in Table IV. The testing capabilities include mechanical properties test, chemical analysis, metallurgical evaluation, non-destructive evaluation, thermal properties measurement, and other related properties testing. The examples of mechanical properties test are yield strength, hardness, high cycle fatigue, low cycle fatigue, creep, Youngs modulus, and Poissons ratio. The thermal properties of materials include, but are not limited to, coefficient of thermal expansion, specific heat, thermal conductivity, and thermal diffusivity. The metallurgical analysis can survey, but is not limited to, grain size and distribution, fractography examination, phase and defect evaluation. The examples of physical properties are densities and ductility. The chemical analysis can be used to investigate material corrosion resistance, composition, and flammability.
