摘要：
Use of the Sieverts technique has made it possible to study the interaction of N-2/Ni-Cr liquid alloys at 1 873 K. We have shown that the dissolution of nitrogen in these alloys obeys the law of Sieverts. Experiments show that the nitriding reaction of a Ni-20 % Cr alloy is controlled by overall kinetics of the first order while the denitriding reaction is governed by the overall kinetics of the second order.
