Opis (eng)

Abstract: Brazing technology requires some demands between the filler metal and parent metal, most of them are related to the strength, corrosion resistance, wettability, melting temperature, etc. One of the main characteristics of the shape memory alloys (SMAs) is in its temperature of martensitic transition, i.e. when such alloy became a “memory alloy“. The joining of the SMA sometime becomes necessary. There are a few fusion methods for joining of the SMA; one of them is brazing, but then the relation between the melting temperature of a filler metal and temperature of a martensitic transformation at the SMAs becomes very important. The higher melting temperature of filler metal than the martensitic transition temperature certainly will affect changing the important properties of the SMA. So, the troubles in choosing the melting temperature of a filler metal for brazing any kind of the SMAs will arise. Further, the brazing technology will affect the metallurgical properties not only on the joint, but also on the final product to be made.
