Conclusions
-
1.
The infiltration of titanium carbide with high-speed steel for 30 min at 1500°C in a hydrogen atmosphere has practically no effect on the grain size of the starting TiC powder. By using fine starting titanium-carbide powders, alloys were obtained containing 52% of fine grains.
-
2.
Additional heat treatment of the resulting alloys for 20 min at 1600°C was found to produce marked grain growth and to accelerate the process of formation of a ring-type structure; such a structure is apparently due to a sharp gradient of steel-component concentration across the section of the carbide grains.
-
3.
Infiltrated alloys with a finer-grain structure exhibit increased hardness and wear resistance.
