EXPERIMENTAL STUDY ON FRACTURE TOUGHNESS OF MULTILAYER WELD JOINT BASED ON MICROSTRUCTURE

EXPERIMENTAL STUDY ON FRACTURE TOUGHNESS OF MULTILAYER WELD JOINT BASED ON MICROSTRUCTURE

Quasistatic fracture toughness tests have done on SAW multilayer weld joint of Ni Cr Mo V scaled steel. The test result shows that the dispersion of fracture toughness J of SAW multilayer weld joint was large. J-R fracture resistance curve was fit and critical Jc（ 25）with pop-in behavior were calcul...
