| Popis: | Alternating current accelerates stress corrosion cracking of grade X70 pipe steel in electrolytes of various compositions: 3.5% NaCl solution (pH 7), citrate buffer (pH 5.5), and a mixture of NS4 solution with borate buffer (pH 7). The increase in crack growth rate upon static load and deterioration of steel crack resistance during constant extension rate testing correlate with an increase in the metal corrosion rate. |
