Metal matrix composites (MMCs) have gained a

considerable interest in the last three decades. Conventional powder

metallurgy production route often involves the addition of reinforcing

phases into the metal matrix directly, which leads to poor wetting

behavior between ceramic phase and metal matrix and the

segregation of reinforcements. The commonly used elements for

ceramic phase formation in iron based MMCs are Ti, Nb, Mo, W, V

and C, B. The aim of the present paper is to investigate the effect of

sintering temperature and V-B addition on densification, phase

development, microstructure, and hardness of Fe–V-B composites

(Fe-(5-10) wt. %B – 25 wt. %V alloys) prepared by powder

metallurgy process. Metal powder mixes were pressed uniaxial and

sintered at different temperatures (ranging from 1300 to 1400ºC) for

1h. The microstructure of the (V, B) Fe composites was studied with

the help of high magnification optical microscope and XRD.

Experimental results show that (V, B) Fe composites can be produced

by conventional powder metallurgy route.
