摘要

通过Gleeble-1500热模拟机研究了Nb含量对10 kg真空感应炉熔炼的铸态HP40合金(%:0.40C、25Cr、35Ni、0.15Mo、0.05Ti、0.4～2.1Nb)1 150℃抗氧化性和抗拉强度的影响。结果表明

0.8%Nb时

HP40合金具有最佳的综合高温性能:在1 150℃合金氧化增重最低

为0.766 g/(m

·h)

抗拉强度最高

为52 MPa。

Abstract

Effect of Nb content on oxidation resistance and tensile strength at 1 150 T of as-cast alloy HP40 ( % : 0. 40C

25Cr

35Ni

0. 15Mo

0. 05Ti

0. 4 〜2. 1 Nb) melted by a 10 kg vacuum induction furnace has been studied by Gleeble-1500 thermal simulation machine. Results show that the HP40 alloy contained 0. 8% Nb has excellent comprehensive high temperature properties that is at 1 150 ℃

the oxidation weight gain- 0. 766 g/( m

·h) is lowest and the tensile strength (52 MPa) is highest.
