Development of new microalloyed steel by alloying with tungsten

Journal Article


Abstract


  • The effects of tungsten (W) addition on the microstructure, impact toughness and tensile properties of a microalloyed cast steel were systematically investigated. The results indicate that W alloying in microalloyed cast steel plays a positive role in inhibiting dendrite during casting process, and the yield strength, ultimate tensile strength and fracture strain can be simultaneously improved after W addition. Both microalloyed cast steels with and without W additions show very low impact energies, indicating W addition has no significant effect on the impact toughness. The present work provides a possibility to develop new W-containing microalloyed steels with improved mechanical properties.
