چکیده

in this research, al-ni particle composite strips are formed by accumulative roll bonding (arb) process using al strips and ni powder. the rule of arb cycles and volume percentage (vol%) of ni powder on the microstructure, wear resistance and mechanical properties of the formed composites are investigated. according to the tensile test results, the yield stress and tensile strengths of the al -ni (p) composites tend to increase with rising of the arb cycles. ductility of the arb samples significantly decreased in the first cycle of the arb process and then elevated lightly from the second pass of the arb. furthermore, the yield stress and tensile strengths of the al - ni (p) composites with different vol% of ni powder, increased with increasing the amount of ni powder. also the hardness and wear resistance of produced composites were investigated. micro hardness and wear resistance of these composites increased with increasing the number of arb cycles and the amount of ni particles content during arb process.
