Growth Kinetics of Particles of Nitrides in Process of High-Temperature Volume Nitriding of Wrought Alloy of Ni-Co-Cr-W-Ti System

摘要

The laws of nitride phase formation are studied for the Ni-Co-Cr-W-Ti new class heat-resistant alloy, strengthened by volume nitriding. The data on kinetic features of behavior of the alloy during ther-mochemical treatment are obtained: the dependences of the extent of structural zones and particle size of the nitrides on the treatment time are found. A kinetic model of the volume nitriding process is proposed.
