Influence of spinodal decomposition on magnetic properties of Fe sub 28 Cr sub 16 Co

For two iron alloys with 25-28% Cr, 16-18% Co and additions of aluminium and titanium a microstructure of phases alpha and gamma was obtained after quenching from annealing at 1200 deg C. Hardness and magnetic properties grow up to 30-40 min of annealing at spinodal decomposition temperature 630 deg...

Description
Summary:For two iron alloys with 25-28% Cr, 16-18% Co and additions of aluminium and titanium a microstructure of phases alpha and gamma was obtained after quenching from annealing at 1200 deg C. Hardness and magnetic properties grow up to 30-40 min of annealing at spinodal decomposition temperature 630 deg C. By longer annealing hardness remains virtually unchanged, while magnetic properties decrease slightly. By isochromal annealing in a temperature range of 620 to 650 deg C the maximal hardness in attained at 620-630 deg C and best magnetic properties at 640 deg C. The optimal combination of magnetic properties and ductility is attained after spinodal decomposition at 640 deg C.
