【Abstract】 Taking structural steel (40Cr) and tool steel (T10A) as an object of study,effect of two different structure ultra fining treatment technology before welding (salt bath cyclic quenching and high frequency hardening )on the deformation characteristic of isothermal superplastic welding joint has been examined.The experimental results indicates:The finer the structure before welding,the bigger the welding joint deformation.In comparison with 40Cr side,the welding joint deformation of T10A side is evenly bigger.更多还原
