Abstract: 

In this Study, the effects of heat treatment parameters on the microstructure and mechanical properties of interfacial intermetallic that was produced during explosive welding of 321 austenitic stainless steel and 1230 aluminum alloy were investigated. The interfacial intermetallic were evaluated by optical microscopy (OM), Scanning electron microscope (SEM), micro hardness testing and tensile-shear test. The diffusion of aluminum, iron, nickel and chromium elements were studied by linear energy-dispersive X-ray spectroscopy method. The interface before heat treatment changed from smooth to wavy shape with increasing the stand-off distance from 1 mm to 2.5 mm. The intermetallic layers thickness also raised from 3.5 mm to 102.3 mm. The micro hardness of the samples with 1 mm stand-off distance was 766 HV that increased to 927 HV in the samples with 2.5 mm stand-off distance which was related to the amount of intermetallics. The proportional amount of strength were 103.2 MPa and 214.5 MPa in the above samples respectively. Heat treatment at 45oC for 6 hr. resulted in intermetallic thickness reaching to 4.4 mm in the samples with 1 mm stand-off distances and to 118.5 mm in the samples with 2.5 mm stand-off distances. These results showed that the increase in heat treatment temperatures and times reduced the micro hardness and strength level.
