抄録	For evaluation of wear behavior in the sliding conditions, powder metallurgy Mg97Y₂Zn₁ alloy composites reinforced with additive Mg₂Si particles prepared via the repeated plastic working (RPW) process were investigated. The RPW process was effective in refining Mg₂Si particles of 5 to 10 wt% and grains of the matrix via dynamic recrystallization. When increasing the repetition number of RPW process from 200 to 600 cycles, the particle size of Mg₂Si additives changed from 8μm to 1～2μm, and the grain size of the magnesium matrix was 1μm or less. With regard to the defensive and offensive behavior in wet wear test, this composite had superior adhesive wear resistance compared with the conventional magnesium alloys because of its high matrix hardness at elevated temperature. The uniform distribution of refined Mg₂Si particles was useful for improving both defensive and offensive properties against AZ31B counter disk specimens. Deep scratches of the disk surface were caused by coarse Mg₂Si additives, and resulted in an unstable and high friction coefficient.
