A phase diagram for Fe-4 wt%Si in comparison to that of pure iron (Komabayashi 2014). The fcc–hcp transition boundaries and melting curve of the hcp phase were calculated with ideal mixing of Fe and Si, while the other boundaries including the melting curve of the fcc phase were schemat...
phase diagramThe samples of SiC-Si3N4-Gd2O3 system were prepared by a hot pressure sintering(HP) method in N2 and Ar atmospheres at 1 700 ℃.The phase compositions of the samples were analyzed by X-ray diffraction to determine the phase relations.The results show that,except for Si3N4·...
The quasi-one-dimensional compound BaCu2Si2O7 demonstrates numerous spin-reorientation transitions both for a magnetic field applied along the easy axis of magnetization and a magnetic field applied perpendicular to it. The magnetic phase diagram for all three principal orientations is obtained by mag...
From the ELF isosurface of tP8-MgO3 illustrated in Fig. 2c, we can also confirm the existence Scientific Reports | 5:18347 | DOI: 10.1038/srep18347 3 www.nature.com/scientificreports/ Figure 2. (a) Pressure-composition phase diagram of the Mg-O system and illustration of (b) ...
one of which is of course the chemical formula of the composition which has to be compatible with the predominant presence and stability of at least one solid solution. One skilled in the art can easily determine by means of the phase diagram of the system in question whether an envisaged fo...

In the AlN-corner of the phase diagram different polytype-alike structures exist (polytypoids or chemical polytypes), which are built by stacking of the Al–N–(O) layers (tetrahedral coordinated aluminium) with additional interlayers, where the aluminium is sixfold-coordinated to compensate the ...
It was obvious that with the addition of Si content, the density of the second phase gradually increased and the distribution was more uniform, contributing to more significant dispersion strengthening. In the distribution diagram of each element in the 1280-S3 ODS steels (Figure 6), it could ...
We analyze the zero-temperature phase diagram of the spin-1/2 quantum XXZ chain in the presence of weak disorder. The effects of various random perturbatio... CA Doty,DS Fisher - 《Physical Review B Condensed Matter》 被引量: 135发表: 1992年 Quasi-1D spin-1/2 Heisenberg magnets in t...
