中文摘要：
在氩气保护精炼条件下研究了煤粉、石墨粉、碳纤维等形态的碳元素对AM60镁合金组织与性能的影响，探讨了C元素对其合金组织的细化机理。研究结果表明，在AM60镁舍金中加入少量不同形态的碳元素能有效地改善其显微组织，使AM60镁合金的铸态室温力学性能有了不同程度的提高；当碳以纤维状态加入时，合金室温铸态力学性能的提高幅度最大，其抗拉强度和延伸率分别达到了242．4MPa和13．2％，分别在原合金的基础上提高了23％和2．5倍。
英文摘要：
Effects of C addition in different forms, such as coal powder, graphite powder and carbon fiber,on the microstructures and mechanical properties of the AM60 alloy were investigated, and the refinement mechanism of alloy microstructures by C was disoussed. Results show that a little amount of C addition to AM60 refines the microstructure of magnesium ingot. Owing to the improvement of microsturcture, the mechanical properties of alloys at ambient temperature are increased. The mechanical tests indicate that AM60 alloy has the best properties when the form of the C is C fiber. Maximum tensile strength and maximum elongation are 242.4 MPa and 13.2%, increased by 23% and 2.5 times respectively.
