Magnetic Structural-Phase Analysis as Applied to Diagnosing and Evaluating the Lifetime of Products and Structural Components. Part 1

摘要

This paper initiates a survey of original papers on various divisions of magnetic structural-phase analysis. A schematic “tree of magnetic structural-phase analysis” has been drawn up, which offers an insight into the state of the art and prospects in the application of magnetic techniques to evaluating the structural state, phase composition and physical-mechanical properties of rolled stock, heat-treated steel and cast-iron products, to the nondestructive testing of the depth and hardness of layers in face-hardened products; it also gives an idea of laboratory and in-situ procedures of performing a magnetic phase analysis. Considering that the survey is extensive, it is divided into several parts.
