38 fe si phase diagram

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. 307 A.

Fe si phase diagram. Al-Fe-Mn-Si phase diagram can be used to analyze the effects of Fe and Mn on the phase composition of casting Al-Si alloys of the 4XX.0 series. In many cases, this quaternary diagram solely makes it possible to answer the question as to which Fe-containing phases can be formed in a particular commercial alloy. 1.1.

Abstract. In this work Thermo-Calc software was used to calculate the phase diagram of the Fe-Si system. The deduced phase diagram includes twenty fields, where three fields represent pure phases; two solid solutions and a liquid phase. There are several fields of two co-existing phases; mixed solid phases, and mixed solid with liquid phases.

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.

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.
