Abstract

This paper presents results from an analytical and experimental study of the effect of magnetic fields on the fracture properties in a nickel-iron superalloy (Incoloy 908). The tensile, notch tensile and small punch tests were employed at liquid helium temperature (4 K) in magnetic fields of 0 and 6 T (T; tesla). A finite element analysis were also preformed to convert the experimentally measured load-displacement data into useful engineering information.
