Investigation of Mechanical Properties in Brazing of Ti-6Al-4V and SS410 in Vacuum

In this research، Ti-6Al-4V alloy was brazed with 410 stainless steel by three different filler metals as silver-base، nickel-base، and titanium-base alloys. In order to obtain optimum clearance، brazing was done in three different clearances of 0. 02، 0. 04 and 0. 06 mm. Also، the strength and hardness of the brazing zone were investigated. The results of shear strength showed that the brazed samples with titanium-base alloy at the clearance of 0. 02 mm had the maximum strength among the different samples which was 149. 5 MPa.
