摘要
采用真空烧结技术制备了丝径为12μm的金属纤维多孔材料,利用扫描电子显微镜观察了金属纤维多孔材料的形貌,用MTS858压缩试验机研究了金属纤维多孔材料的准静态压缩性能。结果表明,所制备的金属纤维多孔材料的孔隙形貌复杂,其压缩应力-应变曲线光滑,屈服平台区没有凹陷,随着孔隙度的降低,金属纤维多孔材料的屈服强度增大。
In this paper, porous metal fibers with open porosity have been prepared by using vacuum sintering technology. Diameter of the stainless steel fibers is 12 μm. Morphology of the porous metal fibers was investigated by means of scanning electronic microscopy （SEM） and the compressive properties of the porous metal fibers were studied in quasi-static condition by using MTS858 system at room temperature. The results indicated that microstructure of the porous metal fibers exhibit more complicated. Moreover, the stress-strain curves for porous metal fibers exhibit smooth stages and no collapse during plateau stage. The yield strength of the samples increased with the decreasing of the porosity of porous metal fibers.
