Abstract
In this study, austenitic stainless steel AISI 316L has been selected to investigate the effect of aging time and temperature on tensile strength using (ABI) technique. Heat treatment consisted of aging at temperature of 400 oC, 600 oC and 800 oC and socking time for 0.5, 1.5, 10, 24 and 72 hrs.For microstructure examination, an optical microscope were used. The results showed that with increasing the aging time at 400 oC and 600 oC the tensile strength will increase but this approach inverted at 800 oC. These results could be attributed to some metallurgical transformation that occurs during heat treatment like changing in grain size, carbide and nitride precipitation along the grain boundaries, and secondary austenite.
