摘要 以316 L、6 μm不锈钢纤维为研究对象,研究了烧结温度对不锈钢纤维烧结毡拉伸性能的影响。通过SEM对不同温度制备的不锈钢纤维烧结毡的微观结构进行表征。结果表明,烧结温度低于1 200℃时,纤维之间搭接点烧结不牢固,导致纤维毡拉伸性能降低;烧结温度高于1 200℃时,纤维中晶粒容易长大,纤维表面易出现竹节状结晶,导致纤维毡拉伸性能降低;烧结温度在1 200℃时,制备出抗拉强度达31 MPa和延伸率约为10%的不锈钢纤维毡。因此,保证形成高强度烧结结点同时避免形成粗大竹节状晶粒是制备高强度、高韧性不锈钢纤维烧结毡的关键。

Abstract: Taking 316 L-6 μm stainless steel fiber as the research object,the effect of sintering temperature on the tensile properties of stainless steel fiber sintered felt is deeply studied.Microstructures of stainless steel fiber sintered felt prepared at different temperatures are characterized by SEM.The results show that as the sintering temperature is lower than 1 200℃,the lap joints between the fibers are not sintered firmly,resulting in a decrease in the tensile properties of the fiber felt;as the sintering temperature is higher than 1 200℃,the crystal grains in the fiber grow easily,and Bamboo-like crystals are prone to appear on the fiber surface,resulting in a decrease in the tensile properties of the fiber felt;as the sintering temperature maintains at 1,200℃,a stainless steel fiber felt with a tensile strength of 31 MPa and an elongation of about 10% is prepared.Therefore,to ensure the formation of high strength sintering nodes and avoid the formation of coarse bamboo like grains is the key to obtain high strength and high toughness stainless steel fiber sintered felt.
Key words:  sintering temperature    stainless steel fiber sintered felt    tensile property
