The influence of the conditions of complete and incomplete postwelding annealing on the strength properties of the welded joints of a VT41 alloy is studied. These annealing conditions are developed for the ring welded joints of a VT41 alloy. The optimum conditions are determined for the production of large welded joints of a VT41 alloy for a high-pressure compressor in an advanced engine. The mechanical properties of the base and weld metals are compared after complete and incomplete postwelding annealing. The microstructure of the welded joints after heat treatment is investigated. 相似文献

This paper deals with the importance of crystallographic texture as one of the design criteria for the development of advanced steels. The importance of texture has been highlighted by considering the cases of three important grades of steel, such as the electrical-, the deep-drawing quality- and the linepipe steels. In each case the evolution of texture as a function of the compositional and processing variables has been evaluated. This has clearly shown that texture is as fundamental as the microstructure in deciding the properties. 相似文献
