中文摘要：

类似的散开 1Cr11Ni2W2MoV 不锈钢结合在不同结合温度被进行。接口特征和关节的机械性质被检验，并且界面的空形态学的进化详细被分析。结果证明有四典型界面的空形状，顺序产生：大蓬乱的虚空，塑造便士的虚空，椭圆虚空和圆虚空。当空体积的减小在虚空，接口散开和卷散开附近被归功于到材料的塑料流动的联合效果时，界面的空形状的变化被表面散开统治。由于从结合的接口的虚空的消除，获得的健全关节能展出将近完整的界面的接触，并且介绍优秀机械性质，在哪个 microhardness 并且砍关节的力量基础材料匹配那些。

英文摘要：

Similar diffusion bonding of 1Cr11Ni2W2MoV stainless steel was conducted at different bonding tem- peratures. The interface characteristics and mechanical properties of joints were examined, and the evolution of interracial void morphology was analyzed in detail The results showed that there were four typical interfacial void shapes generating sequentially： the large scraggly voids, penny-shaped voids, ellipse voids and rounded voids. The variation of interracial void shape was dominated by surface diffusion, while the reduction of void volume was ascribed to the combined effects of plastic flow of materials around voids, interface diffusion and volume diffusion. Owing to the elimination of void from the bonding interface, the sound joint obtained could exhibit nearly full interracial contact, and present excellent mechanical properties, in which the microhardness and shear strength of joint matched those of base material.
