It is evident from Figure 6 (Fe-Cr-C phase diagram) that typical martensitic steels should exhibit ferrite and M 23C 6in equilibrium at for example, 600°C. In practice, this carbide is only found after relatively long ageing. because it is preceded by Intermediate phases in the sequence cementite, M 2X and M 7C 3, leading finally to M 23C 6.

The graph is quite complex but since we are limiting our exploration to Fe3C, we will only be focusing up to 6.67 weight percent of carbon. This iron carbon phase diagram is plotted with the carbon concentrations by weight on the X-axis and the temperature scale on the Y-axis. Iron crystal structures explained

The phase diagram of the Ti-Fe-Cr ternary system is fundamental to developing novel alloys containing the elements. Some high hydrogen storage capacity alloys are based on the Ti-Fe-Cr system, it was demonstrated that Fe can partially substitute V and in this way the cyclic durability of alloys will be improved [1], [2], [3].

Phase diagrams at intermediate temperatures are critical both for alloy design and for improving the reliability of thermodynamic databases. There is a significant shortage of experimental data for phase diagrams at the intermediate temperatures which are defined as around half of the homologous melting point (in Kelvin). The goal of this study is to test a novel dual-anneal diffusion multiple ...

The phase diagram of the Fe-Cr binary system is at Fig 1. The melting point of Fe and Cr is taken at the pressure of 1 atmosphere as 1538 deg C and 1907 deg C respectively. The sigma phase, which is an intermetallic FeCr compound, can sometimes form in Fe-Cr alloys, such as AISI 316 or AISI 310 stainless steels.

The re-calculated phase diagram of the Fe-Cr system based on the present study is shown in Fig. 1. As expected, the FCC γ-loop is observed on the Fe-rich side. The BCC phase has a large miscibility gap between Fe-rich (BCC) and Cr-rich (BCC') alloy compounds. σ phase is stable at elevated temperatures. Download : Download high-res image (105KB)

Methods The Fe-Cr-Al phase diagrams and elastic properties are investigated in the following way. The ﬁrst-principles calculations give the stable phases and elastic properties at zero temperature. Then the results are extended to ﬁnite temperature by means of the cluster variation method (CVM) [30,31] and cluster expansion method(CEM) [32].
