Microstructural Characterization and Phase Diagram ... A systematic characterization of a less known Al, Fe, Mn, and Si phase in a SiC particulate-reinforced 2014Al composite (SiC p /2014Al) was performed. In addition to the expected CuAl 2 phase, the Al, Fe, Mn, and Si phase was formed as either an adhesion (>1 µ m) onto SiC in the as-cast composite, or as a precipitate (<100 nm) in the matrix after hot extrusion.

Fe si phase diagram. The Fe-Si phase diagram: from electrical steel to the ... The standard phase diagram for Fe-Si is the one by Kubaschewski (1982). In the iron-rich region, the dominant phases are a-Fe (0 at.%. Si), DO3 (a1, 25 at.%. Si) and B20 (e, 50 at.%. Si). a and a1 have the bcc lattice as underlying lattice, and a1 consists of an ordered replacement of one quarter of the Fe atoms by Si.

PDF The Al-Si Phase Diagram - Buehler The Al-Si Phase Diagram The binary Al-Si phase diagram was initially studied by Fraenkel of Germany in 1908. It is a relatively simple binary diagram where there is very little solubility at room temperature for Si in Al and for Al in Si. Thus, the terminal solid solutions are nearly pure Al and Si under equilibrium conditions.
