ENVIRONMENTAL FAILURE AND PREVENTION OF MATERIALS
(0) The paper reviewed the environmental degradation of mechanical properties of various materials, i.e., magnesium alloy AZ91D, low alloy steel A537 and aluminum alloy LY12CZ. The relative humidity and corrosive environment have much influence on the mechanical properties, including yield strength, ultimate strength, elongation, fatigue strength, plastic zone in the vicinity of crack tip etc. The loading procedures for corrosion and fatigue also have strong effect on the final fatigue lifetime. Therefore, for mechanical design and failure analysis, the environment conditions should be considered. To separate the material and environment by using coatings, to obtain compact surface film by modifying the surface properties, or to develop the corrosion resistant materials to against environmental failure are very important to improve the lifetime and reliability of engineering structures and components. The possible consideration against environmental damage and materials degradation control methods were proposed.
