high-strength, education, weichmagnetische co fe - c alloy

摘要

A magnetically soft, Co-Fe-C alloy is disclosed which contains in weight percent, about - Carbon 0.05-0.50 - Manganese 0.5 max. - Silicon 0.5 max. - Phosphorus 0.01 max. - Sulfur 0.01 max. - Chrominum 1.0 max. - Nickel 1.0 max. - Molybdenum 0.25 max. - Cobalt 14-28 - Vanadium 0.1 max. - Niobium 0.1 max. - Tungsten 0.1 max. - and the balance is essentially iron. The alloy provides a yield strength of up to about 580 MPa (84 ksi) while maintaining ductility and magnetic induction comparable to the known 27Co-Fe soft magnetic alloy. Magnetic and mechanical properties are developed through an annealing heat treatment which is performed after the alloy has been mechanically worked and machined to final shape.
