Stainless Steels and Alloys in air and space‐craft

Materials and particularly metals for use in producing modern aircraft and space vehicles must have the ability to withstand damage, and this requirement becomes increasingly important. For example, if the materials used have high mechanical strength, corrosion‐resistance and tensile strength, they do not automatically become ideal choices. The properties more specifically asked for are the ability of the metals to withstand fracture on impact and also the degree to which they are likely to propagate cyclic cracks.
