摘要
Abstract
The absorbed energies of X80 pipeline steel at different temperatures were tested through the oscillographic drop-weight tear test, and the load-displacement curve and the hammer speed curve were compared and analyzed, the results showed that the shape of load-displacement curve is different at different temperature, with the temperature decreasing, the lowering speed accelerating when the load reaches highest value. According to the absorbed energy of DWTT, the ductile-brittle transition temperature was draw out, and the ductile-brittle transition temperature curve of X80 pipeline steel was made and compared with that of Charpy impact test.关键词
