摘要： Disclosed herein is a method of producing an ultrafine crystalline TiN/TiB2 composite cermet. In the method, titanium nitride (TiN)/titanium boride (TiB2)/stainless steel composite nanopowder is produced through a reaction milling process using titanium (Ti), boron nitride (BN), and stainless steel powders as raw material powders, and the resulting composite nanopowder is liquid-phase sintered. The method comprises a first step of mixing titanium powder and boron nitride powder at a molar ratio of 3:2, a second step of mixing 5-60 wt % stainless steel powder and the powder mixture, a third step of feeding the powder mixture along with a ball having a predetermined diameter into a jar and conducting a high energy ball milling process to produce titanium nitride/titanium boride/stainless steel composite nanopowder, and a fourth step of shaping and sintering the resulting composite nanopowder.

摘要： The present invention relates to a method of fabricating ultra-fine grain cermet alloys with a homogenous solid solution grain structure. More particularly, the invention relates to a method of fabricating an ultra-fine TiC-base cermet alloy with a homogenous solid solution structure which does not comprise a core-rim structure in the carbide grain.The object of the present invention is to provide a method of fabricating a TiC-base cermet alloy without the core-rim structure.The above objects of the present invention could be achieved by employing a conventional sintering process (vacuum sintering) of (Ti,TM)C carbide obtained from a mechano-chemical synthesis (high energy ball-milling) from milling the powders of Ti, TM, Ni and Co metals.
