METHOD OF POST-PRODUCTION THERMAL TREATMENT OF ADDITIVELY PRODUCED PRODUCTS FROM STRENGTHENED GAMMA-APPLICATION PHASE OF SUPERMARTS |
| abstract |
The invention relates to the field of metallurgy, in particular to methods of additive manufacturing products. The method of additive manufacturing of a product from a γ′-phase strengthened Ni-based and / or Co and / or Fe-based superalloy, or a combination thereof, includes the provision of an additively manufactured product and its heat treatment. Heat treatment is carried out first by heating the product from room temperature (RT) to a temperature T 1 with a heating rate v 1 , with the temperature T 1 being 50-100 ° C lower than the temperature T s beginning to reduce the thermal expansion coefficient, and holding the product for a time t 1 at T 1 to achieve a uniform product temperature. Then, by heating the product at a heating rate of v 2 at least 25 ° C / min from T 1 to a temperature T 2 ≥ 850 ° C, which eliminates or at least reduces the release of the γ′-phase. Get products without cracks compared with significant cracking of the heat-treated products in the traditional way. 5 hp f-ly, 5 ill. |
