Abstract: A method for manufacturing a component or coupon made of a high temperature superalloy based on Ni, Co, Fe or combinations thereof includes forming the component or coupon using a powder-based additive manufacturing process. The manufacturing process includes completely melting the powder followed by solidifying the powder. The formed component or coupon is subjected to a heat treatment so as to optimize specific material properties. The heat treatment takes place at higher temperatures compared to cast components or coupons.
