Titanium carbide-based carbide steels made of chips of titanium alloys

Properties and microstructure of carbide steels produced on the basis of titanium carbide are studied. Powdered TiC was obtained from chip wastes of the Ti alloys VT1-0, VT20, VT3-1, VT25, VT5-1, and OT4-1 in three ways: nitriding-carbidizing, double carbidizing, and oxidizing-carbidizing. It has be...

Description
Summary:Properties and microstructure of carbide steels produced on the basis of titanium carbide are studied. Powdered TiC was obtained from chip wastes of the Ti alloys VT1-0, VT20, VT3-1, VT25, VT5-1, and OT4-1 in three ways: nitriding-carbidizing, double carbidizing, and oxidizing-carbidizing. It has been determined that presence of nitrogen deteriorates the properties of carbide steels. The high values of strength and hardness obtained by oxidizing-carbidizing and double carbidizing of VT5-1 alloy chips testify to the advisability of using such chips for producing carbide steels.
