high V-N micro alloy 富氮钒微合金
It is considered that the V-N micro-alloy high carbon wire rods obtain the high strength and toughness mainly due to grain refining and precipitation strengthening.
研究认为钒氮微合金化硬线钢主要通过细晶强化和沉淀析出强化，从而提高钢材的强韧件。
The results show that the wear resistance can be improved by using fine particle, even and high content of V in the alloy.
研究结果表明：合金中V颗粒细小且弥散均匀以及提高V的含量，有利于提高合金材料的耐磨损性能；
