摘　　要：This study researches the effect of V-Nb on the growth of austenite grains in 17CrNiMo6 carburized gear steel.Results show that the carbonitride in V and Nb acts as second-phase particles in the steel,which can be used to block the migration of grain boundaries and the thinning of the austenite grains.This causes the crystals in the V-Nb microalloy 17CrNiMo6 steel to coarsen and the temperature to rise,thus reducing the cost of the carbonization that follows processing on the gears. 关键词：奥氏体钢齿轮物理性质冶金技术
