Effect of the cooling rate on the microstructure of directionally solidified casting (CMSX-4 Ni superalloy)
Abstract: This study investigates the impact of the cooling rates, from 18 to 1.5 °C/s, on the as-cast microstructure of the CMSX-4 Ni-based superalloy, especially on morphological changes in primary γ′ precipitates in the dendrite core and border. Microstructural characterization along the height of directionally solidified samples included the measurement Leia mais…
