Paper Abstract

In this paper , a new technique of measuring steel hardenability is introduced. It is known that the variation in the microstructure of steel products (A-M ) occurs during the course of their hardening , and microstructures (A M P) differ in their characteristics of electromagnetic induction. On the basis of this fact , the analogue curves are detected for the microstructure variation on the cross-sections of the workpieces , and the corresponding mathematic model is studied and established, so the steel hardenability can be calculated. In comparison with the usual hardenability measurement method , the main advantage of the present method is without workpiece broken. In addition , it is adaptable to measure the hardenability for various steel products in different hardening media , and the operation is convenient and rapid. Overall , an unusual way in measuring steel hardenability is initiated.
