1、基于金属粉末微波烧结技术的研究现状郑孝英1，李毅恒2,3，何奥希2,3，冯康露2,3，陈晋2,3，陈菓*,2,3,4(1.昆明冶金高等专科学校，昆明650093;2.云南省跨境民族地区生物质资源清洁利用国际联合研究中心，云南民族大学，昆明650500;3.云南省高校民族地区资源清洁转化重点实验室，云南民族大学，昆明6505003;4.钒钛资源综合利用国家重点实验室，攀钢集团研究院有限公司，攀枝花617000)摘要：由于微波具有高温、高焓、高的化学反应活性、反应气氛及反应温度可控等特点，非常适合制备纯度高、粒度小且粒度分布均匀的新性能材料。本文综述了微波烧结技术对合金性能的
2、影响因素，重点阐述了微波烧结铁基材料、微波烧结软磁铁氧体材料、微波烧结高密度合金、微波烧结硬质合金和微波烧结难融金属对个材料的性能的影响。结果表明：微波烧结相对于常规烧结大大的加快了反应的速度，且烧结材料的各项性能都远远高于常规烧结，且烧结过程的生产周期变短，降低了能耗，提高了生产的效率。关键词：微波烧结；铁基材料；软磁铁氧体材料；合金MicrowavesinteringtechnologyandresearchstatusbasedonmetalpowderZHENGXiaoying1,LIYiheng2,3,HEAoxi2,3,FENGKanglu2,3,CHENJi
