Process for manufacturing a magnetic component ductile magnetic alloy based on iron having a manocristalina structure.

摘要

METHOD FOR PRODUCING COMPONENTS MAGNETIC ALLOY SWEET MAGNETIC IRON-BASED nanocrystalline STRUCTURE, COMPRISING CHEMICAL COMPOSITION WHICH, IN ATOMS PERCENTAGE, FE 60%, 0.1% CU 3%, 0% B 25%, 0% SI 30 % and at least one element selected from the group consisting of niobium, tungsten, tantalum, zirconium, hafnium, titanium and molybdenum in UNDERSTOOD THE MERGER BETWEEN 0.1 to 30%, the OTHER IMPURITIES RESULTING FROM THE PREPARATION AND TURNING THE COMPOSITION RATIO SI + 5% B 30%. According to the invention is manufactured with the magnetic alloy TAPE amorphous THIS IS MADE ONE PIECE TRIMMED COMPONENT MAGNETIC AND EAST SUBMITTING A HEAT TREATMENT crystallizing COMPRISING AT LEAST ONE crystallization annealing at a temperature between 500 And 600 (DEGREES) C for MAINTENANCE between 0.1 and 10 hours, to cause formation of nanocrystals; HEAT TREATMENT PREVIOUSLY Crystallization, PERFORM A RELAXATION HEAT TREATMENT TO A SLOWER TO INITIAL TEMPERATURE AMORPHOUS ALLOY recrystallization temperature.
