摘要：

Boron treatment for Cr-Mo steels has been performed to obtain a higher strength with a heavy thickness. But in these steels, even with the quenched microstructure, microalloying elements affect the toughness on tempering treatment at high temperatures. So, the effect of Ti, B and N on the toughness and microstructures has been investigated in B-treated Cr-Mo steels tempered at high temperatures. The results are reported.
