The metastable and stable phase diagrams of the Fe-C-Si system were to be predicted at temperatures of interest by computer calculations. The calculations were to be based on the thermodynamic properties of the constituent binary systems. These properties include (1) lattice stability parameters which reflect Gibbs free energy differences for a The Ti-Si-N-O quaternary phase diagram • Entire phase diagram can be calculated by taking into account all possible combinations of reactions and products • 4 ternary diagrams of Ti-Si-N, Ti-N-O, Ti-Si-O and Si-N-O were evaluated • additional quaternary tie lines from TiN to SiO 2 and Si 2N 2O A.S.Bhansali, et al., J.Appl.Phys. 68(3 ...

2.1. Al-Mg-Si PHASE DIAGRAM The Al-Mg-Si phase diagram can be used for the analysis of many wrought alloys of 6XXX series and casting alloys of the 356.0 type, provided the concentration of iron impurity is low (Table 2.1). This diagram is also the basic diagram for casting alloys of the 512.0 type that are considered in Chapter 4. The phase diagram of the Fe-Si system has been studied at high pressures and temperatures both theoretically and by DAC experiments (12-14, 30-37). The vast majority of diamond anvil experiments are limited to 200 GPa or below, although recent studies have extended to as high as 400 GPa and 6000 K ( 23 ). The Fe-Si phase diagram: from electrical steel to the planet Mercury. The iron-rich region of the Fe-Si phase diagram is of interest both to the planetology community and the materials engineering community. Indeed, the planet Mercury has a solid inner core that consists predominantly of iron, with some nickel, and a selection of lighter elements.

Al-Fe-Si PHASE DIAGRAM The Al-Fe-Si system is the basic system for the structure analysis of commercial aluminum alloys of the 8111 type, and binary Al-Si alloys which, as a rule, contain an iron impurity (Table 1.1). The aluminum corner of the Al-Fe-Si phase diagram is considered in detail by carried out to plot the phase structure diagram of the Fe-Ca-Si-Al system as a modeling composition of the final alloy by the method of thermodynamic diagram analysis (TDA). TDA allows obtaining data for the system in the form of a phase diagram, each elementary subsystem in this diagram is independent. Subsystem can be regarded as a quasi-system.

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.
