THE EFFECTS OF TEMPER EMBRITTLEMENT ON THE MAGNETIC AND MECHANICAL PROPERTIES OF NICKEL-CHROMIUM STEELS

This paper describes a series of measurements made on several different types of steel in order to investigate changes in the magnetic properties as a function of temper embrittlement. The results show systematic changes in the magnetic properties which are attributed to grain boundary segregation of strengthening impurity elements. It appears from the work that magnetic inspection methods have excellent potential for utilization in the nondestructive evaluation of temper embrittlement in ferritic steels.
