, in recent years, DRX phenomena were found in pure Al, Al-Mg, and Al-Zn alloys; and these alloys usually undergo continuous (CDRX) rather than discontinuous (DDRX) dynamic recrystallization during high temperature deformation[2, 4-5]. 7050 aluminum alloy, a typical Al-Zn-Mg-Cu series aluminum alloy, which belongs to precipitation- strengthened alloy, is widely used due to its high strength and low......

on Ni-25%Cr (mass fraction) reduced the subsequent oxidation rate at 1 000 ℃ to a similar content to that for implantation into the alloy, but no improvement in scale adhesion. PA?L et al[9] found that Ce.... 2 Experimental The GH128 alloy had the following nominal chemical compositions (mass fraction, %): Cr 22, W 9.0, Mo 9.0, Al 0.8, Ti 0.8, C≤0.05, Fe≤1.0, Zr≤0.06, B≤0.05, Ce≤0.05, Mn≤0.05, Si≤0.08......
