尝试在 850、900 和 950°C 的温度下，在 10MPa 的压力下，在 90 分钟的保持时间下，将 AISI 304L 与具有 AISI 304L 中间层的低碳钢进行扩散接合 (DB)。拉伸试验表明，过渡接头的最大拉伸强度达到340.5MPa。对扩散结合样品进行的显微硬度测试表明，在较高温度下会形成更硬和更脆的相。光学显微照片和扫描电子显微镜（SEM）图像显示了晶粒生长、扩散区域的宽度以及界面结构的精细细节。由于断裂发生在母材低碳钢中，扩散接合接头的拉伸强度并未因界面处金属间化合物的形成而受到影响。
The diffusion bonding (DB) of AISI 304L to low carbon steel with an AISI 304L interlayer was attempted at temperatures of 850, 900, and 950°C, with a 90-min holding time at a pressure of 10MPa. The tensile test revealed that the transition joints achieved a maximum tensile strength of 340.5MPa. The microhardness test carried out on the diffusion-bonded samples revealed the formation of more hard and brittle phases at higher temperatures. Optical micrographs and scanning electron microscopy (SEM) images showed the grain growth, the width of the diffused region and the fine details of the interface structure. The tensile strength of the diffusion bonded joints was not affected due to the formation of intermetallic compounds at the interface because the fracture took place in the base metal low carbon steel.
