Popis: 1. Together with the familiar low-temperature zone of chemical inhomogeneity (corresponding to 475-degree brittleness), a high-temperature region favorable to chemical inhomogeneity exists in chromium steels. 2. The development of chemical inhomogeneity of the solid solution in terms of chromium apparently makes a larger or smaller contribution to the development of different forms of brittleness in chromium steels: 475-degree brittleness, which is irreversible at 450°C, and reversible temper brittleness. 3. All forms of brittleness in chromium steels are similarly manifested in a change in ability to deform microplastically and, precisely, in an increase in the parameter σ2o, which can be used for the nondestructive monitoring of embrittlement processes.
