In this work, the effect of Nb content on the
microstructures and tensile behaviors of Nb-V added
microalloyed powder metallurgy (PM) steels were investigated.
The samples were pressed at 700 MPa and sintered at 1400°C
temperature in argon atmosphere for 1 hour. Nb-V added PM
microalloyed steels with different niobium ratio were analyzed
by tensile test. The microstructure of the PM steels was
characterised by optic microscope. Results indicated that 0.075
wt. % Nb added PM steel showed the highest values in yield
strength (YS) and ultimate tensile strength (UTS). However,
when the amount of Nb content increased from 0.075 to 5 wt.%,
yield strength and ultimate tensile strength decreased.
Elongation also tends to decrease with increasing Nb content.
