STAINLESS-STEEL SHORT FIBER, AND SINTERED POROUS BODY USING IT

摘要

PROBLEM TO BE SOLVED: To provide a stainless-steel short fiber in which the unevenness of an aspect ratio can be suppressed and to provide a sintered porous body in which the pore characteristics can be stabilized by using the short fibers.;SOLUTION: The stainless-steel short fiber has a columnar shape free from round edge due to cutting at its ends, and fiber diameter (d) is made to ≤10 μm and the average value of the aspect ratio between the diameter (d) and the length (L), L/d, is made to 2-20. The aspect ratio can be reduced by regulating the amount of N in the short fiber to 0.02-0.50 wt.%.;COPYRIGHT: (C)2002,JPO
