Claim 1:
2. A method for manufacturing a Fe—Al-based alloy vibration-damping component, obtaining a vibration-damping component having an irregular sectional shape, the method comprising:
a shaping step in which metal powder comprising 4.0 to 12.0% by mass of Al with the balance being Fe and inevitable impurities is melted and solidified using a heat source with a scanning rate set to 700 mm/s to 1700 mm/s to obtain a shaped product; and
an annealing step in which the shaped product is annealed at a temperature of 800 to 1200° C. to obtain the vibration-damping component having an average crystal grain size in a range of over 740 μm to 2000 μm.
