Microstructure Stability of Inconel 740H Alloy After Long Term Exposure at 750℃

Microstructure Stability of Inconel 740H Alloy After Long Term Exposure at 750℃

Unstressed exposure tests of Inconel 740H alloy tube were carried out at 750℃ for 500-3000h. The microstructure evolution and microhardness were studied by means of thermodynamic simulation, OM, FEG-SEM and microhardness testing. The results show that the tube is qualified if both chemical compositi...
