Abstract Scope |
The paper investigates the effect of hot isostatic pressing of single-crystal nickel-based alloy manufactured by selective laser melting (SLM) with a high-temperature substrate preheating. A study of the structure and phase composition of the material before and after treatment has been carried out. It was found that as a result of such treatment, the ratio and proportion of the strengthening phases changes, however, due to slow cooling after treatment, the optimal ratio and shape of the inclusions is not fixed. In addition, the hardening particles are precipitated. |
