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.
