    摘要:

    Co-Al-W合金是一种由γ′-Co3(Al,W)相沉淀强化的新型钴基高温合金，为了研究含硼元素对不锈钢基体上TIG堆焊层的相组成及开裂行为，通过JMatPro热力学模拟计算软件，对堆焊层Co-8.8Al-9.8W-0.2B合金不同部位析出相的类型、含量进行了模拟计算和实验验证。研究发现，堆焊层0.2B合金不同位置相组成相同，但各相的含量不同。根据对堆焊层合金相组成和相对含量的分析发现，堆焊层表面的裂纹主要为热裂纹，裂纹的形成是热应力、相变应力以及Laves相综合作用的结果。

    Abstract:

    With the precipitation strengthening phase of ternary compound γ′-Co3(Al,W), the Co-Al-W superalloy is a novel cobalt-based superalloy. In order to study the phase composition and cracking behavior of Co-8.8Al-9.8W-0.2B cladding layer on the 304 stainless steel with TIG welding. The phase composition and relative content of elements at different positions in cladding layer were studied with thermodynamic simulation calculation of JMatPro software. The results show that the phase composition should be the same in different position of cladding layer, but the content of those phases are difference. Based on the analysis of the phase composition and content of the elements in the cladding layer, the surface cracks of cladding layer are hot cracks, which are the results of thermal stress, the phase transformation stress and Laves phase.
