| 摘 要： | 研究了经真空电子束焊接+近等温锻造制备的Ti3Al/TC11双合金盘在不同热处理制度处理后的力学性能和显微组织.结果表明,采用梯度热处理的双合金盘的强度稍高;而塑性与变形量有关,当采用40%变形的塑性要高些.热处理制度对焊缝区显微组织有较大的影响.梯度热处理时,焊缝两侧合金的热影响区组织与焊缝中心过渡均匀、无突变,而采用一般热处理制度处理时组织则有明显的突变.热处理制度对双合金盘焊缝的相组成几乎没有什么影响,除了α1,α及β相外,还有新生成的O相,MoNb,Nb,Al及TiAl3相,它仅对组成焊缝的每一个相的含量有一定影响.

| Abstract: | The Ti3Al/TC11 dual alloy discs were joined and deformed by vacuum electron beam welding and near isothermal forging,respectively.Then the tensile properties and microstructure of dual alloy discs processed by different heat treatment regimes were investigated.The results show that the strength of the dual alloy disc processed by gradient heat treatment is higher.However,the plasticity is related to the degree of deformation,and the plasticity of the deformation of 40% is higher.Heat treatment regime has a ... |
