摘要：

In present work, the Fe50Mn30Co10Cr10 metal-matrix composites using graphene as a reinforced phase were synthesized via mechanical alloying (MA) and spark plasma sintering. Alloying behavior, phase evolution and mechanical properties were investigated. The results show that during the MA, a single FCC structure was formed within 50 h ball milling. After sintered, a single face-centered cubic structure was obtained. The addition of graphene increased the room temperature yield strength to the maximum value of 903 MPa, which was 48.7% higher than the Fe50Mn30Co10Cr10 base, accompanied by a decrease in elongation. The results are discussed in terms of mechanisms controlling the strengthening process in composites with matrix.
