摘要
研究了微合金化元素 Nb、 Ti对控轧低合金高强度结构钢力学性能的影响 ,建立了控轧 Nb (0 .0 15 %～0 .0 70 % )和 Nb+Ti (<0 .0 30 % )微合金化低合金高强度结构钢σs、σb。
The influence of microalloying elements Nb,Ti on the mechanical properties of control-rolled high strength low alloy structural steels was studied. The linear progressive equations have been obtained between the yield point, carbon equivalent and the mechanical properties (σ s ?σ b and δ 5) of control-rolled Nb(0.015 %～0.070 %), Nb+Ti (< 0.030 %) microalloyed high strength low alloy structural steels.
