ABSTRACT<br />
Rapidly solidified (RS) D2 steel particle rein<strong>for</strong>ced aluminium matrix composites have been fabricated using<br />
powder metallurgy technique involving sintering and hot pressing. Density of the composites has been found<br />
to be almost 100% that of the theoretical value. The composite containing even 0.9 vol% particles could exhibit<br />
a hardness of 116 BHN as against 40 BHN of aluminium matrix. EDX analysis and microhardness measurements<br />
indicate the presence of (Fe,Cr) 2<br />
Al 5<br />
at the particle-matrix interface. The effect of RS-D2 particles on the wear<br />
resistance of aluminium against 600 grit bonded SiC countersurface has been studied using Pin-on-Disc type<br />
wear set up. The wear resistance of the composites has been found to increase remarkably with the concentration<br />
of RS-D2 particles. The abrasive wear resistance () shows a positive deviation from the rule of mixture. A<br />
five fold improvement in Ω with respect to aluminium matrix has been achieved by incorporating only 2.8<br />
vol% of RS-D2 rein<strong>for</strong>cement.
