1.The dependence of the hardness of titanium-tungsten-cobalt hard alloys on temperature has been found to obey the Ito-Shishokin exponential relationshipH=B · 10-At.2.An increase in the titanium carbide content of hard alloys reduces the inflection temperature of "logarithm of hardness-...
Tungsten steel is a sintered composite material containing at least one kind of metal carbide, and tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, and tantalum carbide are common components of tungsten steel. The grain size of the carbide component is usually between 0.2-10 ...
Steel has a hardness rating of 4.0 to 4.5 and hardened steel has a rating of 7.0 to 8.0 [1], [2]. However, in recent years patients have presented to emergency departments with rings made of much harder materials like titanium (Mohs hardness scale rating of 6.0) and tungsten-carbide (...
The electrochemical behavior of transition metal carbides (tungsten carbide and its alloys [57,58], tantalum carbide [58,59], titanium carbide [58,60], molybdenum carbide [59]) has been reported. These results showed that tungsten and other carbides were unstable at the high potential region ...
