applied loads. From Fig. 2(a), it can be seen that the wear resistance property of B4C/Mg composites is slightly superior to that of pure Mg. Besides, with decreasing the Ti content added into the B4C preform, the wear resistance of B4C/Mg composites is slightly improved. It is obvious that the increased wear property of B4C/Mg composites is mainly due to the superior wear resistance property......
