The infrared rays can easily transmit the transparent quartz tube and be focused on the surface of the specimen. The specimen is locally heated by infrared rays, and the infrared rays much less heat the rest part of the furnace. Consequently, infrared brazing is a highly potential process with the characteristics of both rapid heating (high-energy efficiency) and rapid cooling (quick heat dissipation). The heating rate of infrared brazing can be as high as 50oC/s, so it is a highly potential process. TiNi shape memory alloy (SMA) has the best shape memory properties and biocompatability among all SMAs. The industrial application needs the joining of TiNi SMA to other materials. The purpose of this investigation is concentrated on infrared vacuum brazing TiNi SMA and three dissimilar materials. A project of 3-years term is proposed. In the first year, the project is primarily focused on infrared vacuum brazing TiNi SMA and CP-Ti using three Ag-based filler metals. In the second year, the project is mainly concentrated on infrared vacuum brazing TiNi SMA and Ti-15-3 β-Ti using two Ti-based filler metals. In the third year, the project is mainly focused on infrared vacuum brazing TiNi SMA and Invar alloy and three silver-based braze alloys are chosen as the filler metals. It is expected that the technology of infrared dissimilar vacuum brazing TiNi SMA is developed from this project.紅外線硬銲接合鈦鎳形狀記憶合金純鈦β鈦合金Invar合金Infrared BrazingTiNi shape memory alloyCP-TiTi-15-3 β-TiInvar alloy
