Anodic Dissolution and Crack Growth Rate in Constant Strain-Rate Tests at Controlled Potentials

Source

A theoretical analysis is presented of the constant strain-rate test. The rate of reduction of the cross-sectional area caused by straining is compared with the loss of cross section due to metal dissolution or crack growth, or both. The relationship between the environmental deterioration rate and the strain at which a maximum load is obtained in a constant strain rate test is developed as a function of strain rate. Experimental results of constant strain-rate tests of Type 304 stainless steel conducted in a 10 N sulfuric acid (H2SO4) + 0.1 M sodium chloride (NaCl) solution at various rates are discussed. Measured and calculated crack growth rates show good agreement.
