The diversities and relations of microstructures and properties between the center and surface layer in thick-plate 7150 alloy were investigated by means of OM, TEM, SEM and tensile tests.
But it is difficult to ensure the uniformity of deformation, microstructures and properties along the thickness of the thick plate [8].
And this work is desired to find out the differences and relations between properties and microstructures in the center and surface layers of the thick-plate 7150 alloy under deformation gradients.
