研究了双相不锈钢SAE 2205和中碳钢AISI 1035直接扩散连接接头区域的显微组织和力学性能评价，样品的加工温度为850、900、950和975℃，保温时间为60和90 min，压力为20和30 MPa。能量色散X射线分析（EDAX）和X射线衍射分析（XRD）证实了界面反应产物的存在，例如界面处的西格玛相和金属间化合物。在975℃、90min、20MPa压力下处理的样品的剪切强度为360.9MPa。有趣的是，由于扩散和界面反应而形成硬金属间化合物，接头强度并没有降低。
Microstructural and mechanical property evaluation of the joint region of direct diffusion-bonded joints made between duplex stainless steel SAE 2205 and medium-carbon steel AISI 1035 was studied for the samples processed at temperatures of 850, 900, 950 and 975°C, with holding time of 60 and 90-min and pressures of 20 and 30MPa. The energy dispersive X-ray analysis (EDAX) and X-ray diffraction analysis (XRD) confirmed the presence of interfacial reaction products, such as sigma phase and intermetallics at the interface. The shear strength of the samples processed at 975°C for 90min and at a pressure of 20MPa was 360.9MPa. Interestingly, the capability of the joint strength was not reduced as the result of formation of hard intermetallics because of diffusive and interfacial reactions.
