ABSTRACT:
In a compact formed by subjecting an ultrafine particle brittle material supplied on a substrate to mechanical impact force as a load, whereby the ultrafine particle brittle material is crushed and joined to each other, manganese is added into the ultrafine particle brittle material to form the compact.
