Abstract：
|
|
Processing principles were introduced according to four techniques as follows: equal channel angular pressing(ECAP),cyclic extrusion and compression(CEC),high pressure torsion(HPT) and accumulative roll-bonding(ARB).Research progresses of fabricating aluminum matrix,magnesium matrix and copper matrix ultrafine-grained(UFG) composites by severe plastic deformation(SPD) were systematically discussed.SPD techniques are effective means to refine matrix and homogenize reinforcing phase so as to increase strength,hardness and plasticity.Prospect was also proposed,i.e.,research scope would be widening from nonferrous metals matrix composites to iron matrix,ceramic matrix and polymer matrix composites.
