Two types of duplex stainless steels SAF 2205 and SAF 2305 have been selected in this study to investigate the effect of aging time and temperature on the tensile strength using (ABI) technique. Metallographic studies were conducted on heat treated duplex stainless steels to examine the phase relation ship with tensile strength. The results showed that with increasing the aging temperature from 400co to 800co the tensile strength of duplex stainless steels increased and reached its maximum value at 600co for 72 hrs. At 1000co the tensile strength decreased with increasing the aging time. For both types of duplex stainless steels these results attributed to metallurgical aspects like carbide precipitation, sigma phase, change in grain size, etc.
