oai:localhost:PNK-88312023-08-18T03:17:05Z Analysis of the As-Cast Microstructure and Properties of the Ni-Based Superalloy MAR-M247® Produced Via Directional Solidification Rakoczy, Łukasz Grudzień-Rakoczy, Małgorzata Cygan, Rafał SEM DSC Cc-BY The presented research investigates MAR-M247® Ni-based superalloy castings produced via directional solidification at various mold preheating temperatures (1510, 1566 °C) and withdrawal rates (3.4, 5.0 mm/min). Casting analyses were carried out via thermodynamic simulations, differential scanning calorimetry (DSC), X-ray diffraction (XRD), light microscopy (LM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), scanning transmission electron microscopy (STEM), and tensile testing. On DSC curve, four effects have been registered during cooling: liquidus (1337 °C), formation of eutectic γ − γ′ (1315 °C), precipitation of Ni7(Hf, Zr)2 (1244 °C), and M5B3 borides (1201 °C). The castings’ primary and secondary dendrite arm spacing decreases with increasing withdrawal rates for both shell mold temperatures. 2023-08-18T03:17:05Z 2023-08-18T03:17:05Z 2023 Book https://link.springer.com/article/10.1007/s11661-023-07123-8 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8831 en application/pdf Springer |
