carbide in single crystal superalloy AM3 was systematically investigated with sample growth rates from 3.5 μm/s to 500 μm/s. The carbide morphologies were investigated by scanning electron microscopy (SEM...-cellular (Fig.1(f)). Figure 2 shows the transverse morphologies of the carbides under different withdrawing rates. Several types of carbide morphologies are observed in the etched samples. The first......
morphologies of SiC with different mean diameters are shown in Figure 1. As shown in Figure 1, the 40 nm silicon carbide particles were round, evenly distributed and uniform in size, but also exhibited... J. Cent. South Univ. (2021) 28: 1627-1636 DOI: https://doi.org/10.1007/s11771-021-4722-x Influence of particle size and surfactants on uniformity and quantity of silicon carbide particles......
