采用单辊甩带法制备Ni79Mo10P11箔带,在加热加压的条件下实现碳钢/不锈钢的钎焊,并对试片采用逐次冷轧加热处理的工艺进行处理。通过拉伸试验测试轧制前后冶金层的剪切强度。应用金相观察、EDS成分分析、SEM微观形貌分析等手段,对复合界面附近的组织形貌、元素成分及拉伸后的断口形貌进行了分析。结果表明,冷轧加热处理的方式能显著提高复合板结合强度、减少冶金结合的缺陷。 Ni79Mo10P11 foil was prepared by single-roll rejection method and brazed with carbon steel / stainless steel under the condition of heat and pressure. The specimens were treated by successive cold-rolling heat treatment. The tensile strength of the metallurgical layer before and after rolling was measured by tensile test. The morphology, elemental composition and the fracture morphology after stretching were analyzed by means of metallographic observation, EDS analysis and SEM micrographs. The results show that the way of cold rolling heat treatment can significantly improve the bonding strength of composite board and reduce the defects of metallurgical bonding.
