通过在金属注射成形17-4PH不锈钢中添加微量石墨，研究了碳含量对合金晶格畸变、纳米铜相析出及力学性能的影响。随着碳含量的增加，马氏体畸变程度增加。差示扫描量热法结果表明，随着碳含量的增加，马氏体相变开始温度降低。随着碳含量的增加，纳米富铜沉淀物的平均尺寸逐渐减小。结果表明，试样的抗拉强度和硬度提高，而伸长率相应降低。老化促进更大的纳米铜沉淀物尺寸和轻微改善的机械性能。
By adding trace amounts of graphite to metal injection-molded 17-4PH stainless steel, the effects of carbon content on the lattice distortion, nano-copper phase precipitation, and mechanical properties were studied. As the carbon content increased, the distortion degree of martensite increased. Differential scanning calorimetry results showed that the martensitic phase-transformation starting temperature decreased as the carbon content increased. Moreover, the average size of nano-copper-rich precipitates gradually decreased with the carbon content. As a result, the tensile strength and hardness of the samples increased while the elongation correspondingly decreased. Aging promoted greater nano-copper precipitate sizes and slightly improved mechanical properties.
