意大利比萨大学化学工程系对含钛钢在热轧中由氢引起的裂纹进行了研究。目前研究的重点是观察钛的含量和晶粒尺寸对裂纹的影响情况。试验中 ,将含钛与不含钛钢试样加热到 950、 1 0 50和 1 1 50℃ ,然后随炉冷却 ,获得不同大小的晶粒。将这些试样进行充电试验 ,试验时采用了不 The Department of Chemical Engineering, University of Pisa, Italy, investigated the hydrogen-induced cracking of titanium-containing steels during hot rolling. The focus of the current study is to observe the impact of titanium content and grain size on the crack. In the test, the samples containing titanium and non-titanium were heated to 950, 150 and 1150 ° C, and then cooled in the furnace to obtain different size grains. These samples were charged test, the test was used not
