The effect of solute Cu and Cu precipitates on the wear behavior of ferritic iron under an unlubricated condition was *** specific wear rate of Cu-containing steel abruptly decreased up to 50 N of load,and then gradually decreased with further increased *** specific wear rate of the as-quenched specimen,in which Cu was in a solid solution,was the lowest among all the specimens at low loads,and all specimens had almost the same specific wear rate at high *** observation showed that the hardness increments of all specimens decreased with increased depth below the worn *** as-quenched specimen had a relatively large depth of deformed region than the other specimens even though the increments in hardness were almost the same for all specimens at low *** the same hardness at an unworn state,the as-quenched and over-aged specimens exhibited a substantial increase in hardness and large deformed regions below the worn *** finding indicated that the enhancement in plastic deformation and work hardening led to the decrease in the specific wear rate of the as-quenched specimen at low loads and the improvement in the wear resistance of all specimens at high loads.
