| Abstract Scope |
The slow strain rate tensile (SSRT) test and hydrogen-induced delayed cracking (HIDC) were investigated in a noval bainitic wheel steel. The results showed that hydrogen embrittlement susceptibility of the bainitic wheel steel was really higher than that of ferrite-pearlite wheel steel. The threshold stress intensity factor of hydrogen-induced delayed cracking, KIH, decreased exponentially with the increasing of diffusible hydrogen concentration C0. And the crack propagating rate can achieve as high as 0.2 mm/min when C0=1.6×10-6. |
