Abstract Scope |
Fe-Si alloy with Si content more than 6 wt.% and Fe-49Co-2V alloy demonstrate superior magnetic permeability and high electrical resistivity compared to commercial electrical steel. A near zero magnetostriction is also achieved with Fe-Si alloy. The challenge is to large-scale production of these alloy through traditional routes owing to brittle phase formation during slow cooling. This renders the alloy susceptible to cracking under any deformation process such as hot or cold rolling.
An attempt has been made to produce Fe-6.9Si / Fe-49Co-2V alloy using wire-arc additive manufacturing (WAAM) route. Self-standing crack-free wall was manufactured using a conventional plasma arc torch with cold wire feeding attachment. Electro-magnetic measurements carried out on the deposits indicated magnetic permeability at per with the conventionally prepared alloy. Post deposition solution annealing treatment improved the magnetic permeability appreciably. |
