Constant Strain Rate Technique for Assessing Stress-Corrosion Susceptibility

The constant strain rate technique is a rapid laboratory method to assess susceptibility of metals and alloys to stress-corrosion cracking (SCC). Positive results are obtained since specimen failure occurs, either in a ductile manner or prematurely in a brittle mode if SCC occurs. Experimental apparatus, methods to interpret results, and important experimental parameters are discussed.
