Abstract
The method of making the metal fiber sintered body includes making a coiled material by coiling a thin sheet of Fe--Cr--Al--La, Fe--Cr--Al--Y or Fe--Cr--Al--Ce stainless steel; making a tow of Fe--Cr--Al--La, Fe--Cr--Al--Y or Fe--Cr--Al--Ce continuous fibers by lathe turning an end face of the coiled material at a tool feed speed of from 5 to 40 .mu.m/rev; extending the tow in a width direction and cutting the tow with a roller type cutting assembly to form Fe--Cr--Al--La, Fe--Cr--Al--Y or Fe--Cr--Al--Ce stainless steel fibers having a fiber length of 20 to 200 mm; feeding the Fe--Cr--Al--La, Fe--Cr--Al--Y or Fe--Cr--Al--Ce stainless steel fibers having the fiber length of 20 to 200 mm to a conveyor; dropping the stainless steel fibers onto the conveyor and dispersing the stainless steel fibers by making an air current act on the stainless steel fibers; transporting the resulting sheet-shaped accumulation on the conveyor and compressing it to form a web and sintering the web. The stainless steel fibers have a thickness of from 7.5 to 180 .mu.m, a width of from 10 to 170 .mu.m and are from 17 to 21% by weight Cr, from 2.5 to 6.5% by weight Al, from 0.02 to 0.25% by weight of La, Y o…
