A New Method of Joining Stainless Steels Using Ni micro-plating Bonding Method and Investigation of Mechanical Properties

Stainless steel is applied in a wide range of fields as material with high heat and corrosion resistance. Welding, brazing, solid-phase bonding are the most common joining techniques for stainless steel. Conventional methods have issues such local thermal distortion area need high-temperature treatment at 800-1000°C. In this paper, we investigated new technique With aim establishing technology steel, joined using Ni Micro-Plating Bonding method (NMPB) evaluated shear stress tensile joints. The process performed about 55°C, followed by relatively low temperature 300°C or higher. Shear tests were conducted on NMPB-joined SUS304, results showed that was 114MPa 77MPa without annealing. After 300-400°C 1.5h, 200MPa 240MPa obtained. addition, 600-800°C 1.5h resulted 230MPa 400MPa. plating crystallographic structure before preferential orientation to <001>, but after treatment, recrystallization progressed beyond boundary interface 400°C higher, non-oriented crystalline observed.
