摘要:

对K416B高钨高温合金进行固溶和时效处理以调整其中γ΄相的形貌使其具有两种尺寸，研究了铸态和热处理态合金的拉伸和持久变形行为。结果表明，铸态K416B合金中的γ΄相在基体中分布均匀，其平均尺寸为200 nm，能有效阻碍位错在基体中运动从而使其屈服强度提高。在热处理态的K416B合金中析出了两种γ΄相，其尺寸分别为1 μm和100 nm。在热处理态K416B合金的室温拉伸过程中全位错剪切大尺寸初生γ΄相和以Orowan机制绕过小尺寸二次γ΄，使其屈服强度降低。在高温下二次γ΄相更容易粗化而使γ基体的宽度增大，促进位错剪切γ΄相而使持久应变速率提高。同时，在持久变形过程中纳米级W₆C颗粒在γ-γ΄相界面弥散析出消耗大量W元素降低γ-γ΄两相的错配度，使合金的强化水平下降而导致其持久寿命大幅度降低。

Abstract：

Ni-based superalloys with high W content are widely used to fabricate gas turbine blades because of their high temperature mechanical properties and lower cost. The γ΄-phase is the most important strengthening phase in Ni-based superalloys, which affects the deformation behavior during tensile process. Although the influence of γ΄-phase has been studied extensively, there are few investigations on the deformation mechanism of K416B superalloy with different morphologies of γ΄-phase. Hence, the effect of γ΄-phase morphology on the mechanical behavior of K416B superalloy was assessed in the present work. The average size of γ΄-phase scattered in the as-cast alloy was about 200 nm, which could impede the mobility of dislocations in the matrix so that the yield strength increased. After heat treatment, two sizes of γ΄-phase precipitated from the matrix, the size of them were 1 μm and 100 nm respectively. During room temperature tensile deformation of the alloy after being subjected to heat treatment, dislocations could fully share the primary γ΄-phase particles, and even detour the secondary γ΄-phase particles per Orowan mechanism, therewith the yield strength of the alloy decreased. The life of as-cast K416B is longer than that of the heat-treatment counterpart. It can be interpreted that the secondary γ΄-phase particles coarsened rapidly during the durable test. Additionally, the precipitation of nano W₆C particles along the γ-γ΄ interface depleted tungsten in the alloy, which reduced the mismatch between γ and γ΄ phases, resulting in the damage of the durable life of K416B alloy.
