PURPOSE:To increase coercive force and energy product by adding phosphorus (P). CONSTITUTION:The magnet consists of a composition obtained by adding not more than 0.6pts.wt. phosphorus to a 100pts.wt. alloy consisting of the composition of 68.0-73.0wt% manganese, (1/10Mn-6.6)-(1/3Mn-22.2)wt% carbon and aluminum as the remainder. When the rate (x) of P added exceeds 0.6, x<=0.6 must be formed because nonmagnetic phase in the alloy increases, residual flux density lowers largely and (BH)max also drops after the composition is thermally treated. |
