Effect of Vacuum Environment on Mechanical Behavior.

Abstract

The time to failure and the crack propagation velocity of titanium (6Al-4V) and a 4130 steel were measured as a function of applied potential and concentration of the solutions. A mechanism for stress-corrosion cracking is proposed based on the formation of a strong surface layer. It is also suggested that the films, formed as a result of interaction between the metal and the SCC medium, strongly influence the strength of the surface layer. (Author)
