Microstructure and Identification of Intermetallic Phases three.1. Microstructure and Identification of Intermetallic Phases Figure 1 presents the SEM micrograph and related EDS element map for Material C0. Figure 1 presents the SEM micrograph and connected EDS element map for Material C0. The EDS data have been made use of to determine the secondary phases formed in the matrix alloy. EDS data were employed to identify the secondary phases formed inside the matrix alloy. TheFigure 1.

In addition to towards the Al matrix, the eutectic Si and theSiC particles, several secondary phases Also the Al matrix, the eutectic Si and the SiC particles, many secondary phases had been present with unique morphologies. were present with diverse morphologies.Figure two.

The values offered in Table 22were compared with the atomic composivalues given in Table were compared together with the atomic compotion reported in the GNF6702 custom synthesis literature [305]. The Al content could be greater than expected sition reported in the literature [305].The Al content material can be larger than anticipated from the Benidipine Cancer nominal composition because of the interaction volume with the matrix using the electric beam, with an acceleration voltage of 20 kV. kV.Table 2.
