摘要：

The heat of transport, Q*, for cobalt in α-thorium was determined by a combination of single-phase, steady-state and two-phase, nonsteady-state techniques. The heat of transport, Q*, is temperature-dependent, decreasing from +20 kj/mol at 1125 K to s-60 kJ/mol at 1460 K. This is best described by a linear relation, Q* = 214 s-0.24 T kJ/mol. The observed temperature dependence of Q* can perhaps be attributed to the electronic contribution to the heat of transport, as postulated in Hehenkamp's model. © 1990 The Metallurgical of Society of AIME.
