Overview
Topic status: We're looking for students to study this topic.
Stress corrosion cracking (SCC) results for the residual stresses left behind in metals during the fabrication and weldingstages of certain metals. When these metals are then exposed to a corroding environment the points of stress become nuclei for extremely accelerated corrosion and some of the works more dramatic corrosion related failures. The tradition method of prevention is to relieve the stresses by heat treatment, however, the heat treatment of large structures and repair work can be difficult is not impossible. Another more practical method for specific area is the use of an ultrasonic needle gun which induces a compressive stress at the surface of the metal which is exposed to the corroding environment and has been shown in tests to reduce significantly the effects of SCC. This project will examine the degree to which SCC can be reduced across the surface of the metal and will explore its utility in the metal fabrication industry for a number of metal types.
