Prediction of structural materials performance at long-term service in space conditions
Abstract
An evaluation is made of the factors affecting the performance of materials with weld-jointed structures in the orbital environment. Internal factors familiar from terrestrial applications encompass impurities and material inhomogeneities, property anisotropies, and dislocation densities; external factors unique to the space environment are one-sided cyclic heating, Em radiation, upper-atmosphere corrosion, and particle impacts. These factors can result in mechanical stresses, chemical and electrochemical corrosion, microcracking, outgassing, and phase transitions.
