We discussed the decrease in residual.stress,precipitation evol.tion,and mechanical.properties of GH4151 al.oy in different anneal.ng temperatures,which were studied by the scanning el.ctron microscope(SEM),high-resol.tion transmission el.ctron microscopy(HRTEM),and el.ctron backscatter diffraction(EBSD).The findings reveal.that anneal.ng processing has a significant impact on diminishing residual.*** the anneal.ng temperature rose from 950 to 1150℃,the majority of the residual.stresses were rel.eved from 60.1 MPa down to 10.9 ***,the stress rel.xation mechanism transitioned from being mainl. control.ed by disl.cation sl.p to a combination of disl.cation sl.p and grain boundary ***,the anneal.ng treatment promotes the decomposition of the l.ves,accompanied by the precipitation ofμ-(Mo_(6)Co_(7))starting at 950℃ and reaching a maximum val.e at 1050℃.The tensil. strength and pl.sticity of the anneal.ng al.oy at 1150℃ reached the maximum(1394 MPa,56.1%)which was 131%,200%fol. than those of the as-cast al.oy(1060 MPa,26.6%),but the oxidation process in the al.oy was accel.rated at 1150℃.The enhancement in durabil.ty and fl.xibil.ty is primaril. due to the dissol.tion of the brittl. phase,al.ng with the shape and dispersal.of theγ′phase.
