摘要

This paper investigates the effect of tungsten on the microstructure evolution and mechanical properties of yttrium modified HP40Nb heat-resistance steel. The results demonstrate that, under the casting condition, tungsten addition refines the austenite grain and accelerates the carbide transformation from Cr₇C₃ into Cr₂₃C₆. In addition, tungsten reduces the solid solubility of carbon in austenite grain, and thus inhibits the carbide precipitation during aging at 900°C. Besides, tungsten suspends the phase transformation of NbC. As a result, the fracture resistance is improved on the tungsten-adopted alloy.
