Microstructure and Hardness of Friction Welded SSM 356 Aluminium Alloy

Article Preview

Abstract:

SSM 356 aluminum alloys was obtained from a rheocasting technique named gas induced semi solid process has globular structure on base. The friction welding method conserve microstructure that is similar to the original structure of the base material a globular structure. It is also found that a rotational speed of 1750 RPM, burn of Length of 3.2 millimeters and welding time (upset time) of 30 second can produce a very good weld. The results of the investigation have shown that a have average hardness in the range 58.13 HV.
