Titanium in high-temperature steel

The influence of titanium

When using titanium in small amounts (0.3%), improves long-term strength of heat resistant steels. Plasticity of complex alloyed high-temperature steels, on the contrary, is achieved by the introduction of a large number of titanium. In this case, the titanium in the interaction with carbon it forms a durable connection of the carbides, which do not participate in the processes of dispersion hardening. Therefore, if during the process of formation of carbides of vanadium and chromium, the ratio of titanium to carbon is greater than the value 5:1, a decrease in hardness and strength characteristics of high-temperature steels. Moreover, this process occurs not only at high but also at room temperature.

At the same time, the process of dispersion hardening with the participation of titanium in heat-resistant alloys with intermetallic hardening on the basis of the y-solid solution leads to the formation of y'-phase and a significant increase in the heat resistance of austenitic steels. Titan possesses variable temperature solubility. Therefore, the level of chromium and other alloying elements, the formation of which happens in aging is pre-tempered for a solid solution alloy, is directly dependent kinetics of the formation of y'-phase.
