High Temperature Crack Growth Behavior at Heat Affected Zone
용접열영향부 균열의 고온에서의 성장거동
Abstract
Creep-fatigue crack growth behavior at the heat affected zone of 1Cr-0.5Mo steel weldment has been experimentally studied. Load hold times of the tests for trapezoidal fatigue wave-shapes were varied among 0, 30, 300 and 3,600 seconds. Time-dependent crack growth rates were characterized by the
