摘　　要：烧结不锈钢纤维多孔材料是一种结构功能一体化材料,在冲击能量吸收和过滤分离等领域有广泛应用。利用微波加热法制备了316L不锈钢纤维多孔材料,利用μ-CT,SEM等研究了微波烧结工艺对材料微观结构和力学性能的影响。结果表明微波烧结工艺明显降低了材料的烧结温度,缩短了烧结时间,由此抑制了纤维杆上晶粒的生长,材料的力学性能也得到了提升。微波电磁场在金属纤维间引发的微电弧可起到加快烧结进程的作用。Sintered stainless steel fiber felt（SSSFF） is a kind of porous material promising for functional and structural applications such as energy absorption and solid/gas filtration. In this work microwave heating was used for sintering of 316 L stainless steel fiber felt and the effect of microwave heating on the sintering profile,microstructure and mechanical performance of the sintered stainless steel fiber felt was investigated by μ-CT,SEM and so on. The results show that in contrast with conventional sintering method,microwave heating can sinter stainless steel fiber felt at lower temperature in a shorter time,and the higher mechanical performance of SSSFF can be achieved. The microwave field induced arcing between metal fibers may accelerate the sintering process.
