| Abstract: | The probability and main effect factors of isothermal superplastic welding of 40Cr steel have been examined, microstructure of welded joint and fracture structure surface has been observed and mechanics of superplastic welding has been discussed.After fine-graining treatment and short time superplastic pressing formation under the conditions of superplastic temperature and strain rate,two 40Cr specimens can achieve solid-state bonding and the properties of 40Cr steel in the vicinity of welded area is the same as that of other parts in the specimen. |
