摘要

0Cr15Ni5WMoVNb钢(%:0.068C、14.54Cr、5.32Ni、0.88W、0.92Mo、0.20V、0.10Nb)经5 t中频感应炉+2 t真空电渣重熔炉冶炼

经锻造、热轧成Φ45 mm棒材

试样经1 000℃30 min固溶空冷+-70℃2 h冷处理后进行400～600℃4 h时效空冷。试验结果表明

在450℃时效0Cr15Ni5WMoVNb钢的强度最大

以准解理断裂为主

冲击功低为40 J

随时效温度上升

冲击功显著上升

强度下降

在510℃时效该钢有良好的强韧性

抗拉强度Rm 1300 MPa

屈服强度Rp0.21100 MPa

冲击能AKV 100 J。

Abstract

The studied steel 0Cr15Ni5WMoVNb(%:0.068C

14.54Cr

5.32Ni

0.88W

0.92Mo

0.20V

0. 10Nb)is melted by 5 t medium frequency induction furnace+2 t vacuum electro-slag remelting furnace

then forged and hot rolled to φ45 mm bar products

and the test specimens solid-solution-treated at 1000 ℃ for 30 min +cold-treated at -70℃ for 2 h are aged at 400~600 ℃ for4 h. Test results show that with aging at 450 ℃

the strength of steel 0Cr15Ni5WMoVNb is up to maximum value with main quasi-cleavage fracture and low impact energy-40J

with increasing aging temperature the impact energy of steel increases obviously and strength decreases

and with aging at 510 ℃ the steel has excellent strength-toughness i.e.tensile strengh Rm 1300 MPa

yield strength Ro.21100 MPa and impact energy Akv 100 J.
