The mechanical performance of a nickel boride layer formed on an Inconel 718 superalloy at 1173 K with an exposure time of 6 h and a double aging treatment (DAT) was obtained. The effect of the DAT led to the redistribution of boron and niobium along the depth of the layer-substrate system, increasing the depth of the diffusion zone, and extending the depth of the compressive residual stresses in the layer. In particular, the DAT enhanced the fracture resistance by approximately 1.5 times compared with that of the layer not exposed to the treatment.

时效处理对硼化镍层压痕性能的影响

获得了在Inconel 718高温合金上于1173 K形成的硼化镍层的机械性能，暴露时间为6 h，并进行了双重时效处理（DAT）。DAT的作用导致硼和铌沿层-基底系统的深度重新分布，增加了扩散区的深度，并扩展了层中压缩残余应力的深度。特别地，与未暴露于处理的层相比，DAT将抗断裂性提高了约1.5倍。
