| 摘 要： | 采用逐步熔融凝固法制备了ＷＣ－６５Ｍｎ复合材料，用扫描电子显微镜观察试样的微观形貌和组织结构，并用ＩＭＡＧＥ ＴＯＯＬ软件分析不同试样的扫描图像，定量测定增强相ＷＣ颗粒的分布状况，同时测量材料的抗弯强度和硬度。研究证明电源功率和模具下降速率对增强相ＷＣ颗粒的分布状况和力学性能有重要的影响。电源功率应在５．５￣７．５ｋＷ之间，模具下降速度为８￣１０ｍｍ／ｍｉｎ。

| Abstract: | WC-65Mn metal matrix composites was produced by the IMS (incremental melting and solidification)process in order to research and develop a process making metal matrix composites. The processing parameters of IMS, including power supply and mould velocity of movement etc, were researched.The microstructure was observed by SEM and the distribuions of WC particles were quanficationally measured with the aid of IMAGE TOOL soft, and at the same time the mechanical propertes were tested. The results showed that the distributions of WC particles were uniformity, in addition, the bend strength and degree of hardness were all good at the condition of suitable power supply and favorable mould velocity.IMS process can be a method to produce metal matrix composites. |
