HEAT TREATMENT METHOD FOR REDUCING POLYTHIONIC ACID STRESS CORROSION CRACKING |
| 摘要 |
HEAT TREATMENT METHOD FOR REDUCING POLYTHIONIC ACID STRESS CORROSION CRACKING A heat treatment of alloy 617 generally including 732.degree.C-927.degree.C (1350.degree.F-1700.degree.F) for about one hour. The resultant discontinuous carbide network in the grain boundaries inhibits stress corrosion crack growth in polythionic acid environments.
