Abstract
A process for preparing a duplex ferromagnetic alloy article is disclosed. The process includes the step of providing an elongated intermediate form of a ferromagnetic alloy having a substantially fully martensitic structure. The martensitic intermediate form undergoes an aging heat treatment under conditions of temperature and time that are selected to cause controlled precipitation of austenite in the martensitic alloy. The aged article is then cold-worked to a final cross-sectional dimension, preferably in a single reduction step, to provide an anisotropic structure and a coercivity, H.sub.c, of at least 30 Oe.
