抄録

In order to investigate the mechanism of the solid-solution hardening of titanium carbide by molybdenum, single crystals of various compositions were grown by the r.f. floating zone melt technique and were deformed by compression at temperatures from 1270 to 2270 K and at strain rates from 5×10⁻⁵ to 7×10⁻³ s⁻¹.<BR>The plastic flow behavior was found to be different among three temperature ranges—low, intermediate and high temperature ranges—whose boundaries were dependent on the strain rate. From the observed behavior, it is inferred that the deformation in the low temperature range is controlled by the Peierls mechanism, in the intermediate temperature range by the dynamic strain aging and in the high temperature range by the solute-atmosphere-drag mechanism.
