Heat resisting metal fiber sintered body

摘要

The invention relates to a metal fiber sintered body and particularly to a metal fiber sintered body having high temperature durability made by using as a starting material fibers made by lathe turning an end face of a coil material made by coiling a thin sheet of Fe-Cr-Al-REM stainless steel and accumulating to a predetermined thickness and sintering these Fe-Cr-Al-REM stainless steel fibers. A metal fiber sintered body according to the invention has good and stable mechanical properties at high temperatures of 500 DEG C to 1000 DEG C, and because the sintered body itself has excellent electrical conductivity it does not require a special heat source for temperature holding and temperature holding can be performed by resistance heating of the sintered body itself just by passing a current directly through the sintered body.
