The investigation of thermal conductivity of low-alloyed high speed steels

In the presented work the effective thermal conductivity of three alloyed high speed steels: SW3S2, SW7M and SW2M5 were compared. The thermal conditctivity was received from the simple experiment in which the change of phase metrology-matter was applied. As the metrology-matter gallium was used. The value of the thermal conductivity for high speed steels was compared with date of science literature.
