Abstract

The effects of heat treatment on the structure and magnetic properties of the 80NHS grade permalloy produced by selective laser melting (SLM) of gas-atomized powder are presented in comparison with the properties of the rolled 80NHS alloy. Ring samples either produced by SLM or machined from rolled metal have been studied. It has been established that the magnetic properties of the SLM samples are inferior to the properties of samples produced by thermomechanical processing because the structure of the additively manufactured alloy is characterized by fine grains and a large number of nonmetallic inclusions.
