摘要：
In this paper the effect of temperature and time on M23C6 carbide chemical composition changes is investigated in the temperature range 550-650 degrees C from 100 to 5000 hours. The chemical composition of M23C6 carbides in the steel has been evaluated by means of energy dispersive X-ray analysis (EDX). Experimentally measured results are compared with those obtained by calculations using Hillert-Staffansson model. In the examined time-temperature range the M23C6 carbide was found to achieve the equilibrium composition at the temperature of 650 degrees C after 5000 hours.
