Abstract
Creep deformation localization is generally found in structures at high temperature, typically in weldment. As the heat affected zone (HAZ) in a weldment is very narrow, deformation in HAZ region can hardly be measured by conventional displacement gauge. A new method for measuring long-term local creep deformation was developed by quartz optical fiber and technique of digital image analysis. The creep deformation of base metal, weld metal and HAZ in weldment was thereby determined with cross-weld specimens.
