Our XRD results show that each of the compounds with x <= 0.45 crystallizes in the rhombohedral PuNi(3)-type structure with space group R (3) over barm and Z=9; for the 0.8 <= x<1.0 compounds, each has a hexagonal structure of the CeNi(3) type with space group P6(3)/mmc and Z=6; and each of the samples with 0.45phase mixture of the PuNi(3)- and CeNi(3)-type structures. The calculated XRD intensities of the DyFe(3-x)Al(x) compounds with x=0.2, 0.33, 0.4, and 0.45 indicate that Dy occupies the 3a and 6c sites, Fe and Al distribute randomly on the 18h site, and the 3b and 6c sites are exclusively occupied by Fe, which agrees well with those of our experimental XRD patterns. The XRD intensities of the DyFe(3-x)Al(x) compounds with x=0.8 and 1.0 have also been calculated and found to agree with the experimental results with Dy on the 2c and 4f sites, Fe and Al at the 12k site, and Fe at the 2a, 2b, and 2d sites. In the two-phase region with x=0.45-0.8, the values of unit-cell parameters and phase compositions are linearly dependent on the value of x, indicating that the two phases are constituted by the same composition x with different stacking arrangements. This abnormal two-phase equilibrium is further confirmed by the structural analysis of the DyFe(2.33)Al(0.67) (or x=0.67) sample. The samples with x=1.1 and 1.2 were also analyzed, and each found to be a mixture of more than two phases. (C) 2010 International Centre for Diffraction Data.

The properties of these alloys (e.g., the martensitic transformation temperature T (M) ) sensitively depend on the composition. Understanding the composition dependence of these properties so as to design the alloy as desired is one of the main research topics in this area. In recent years, we have investigated the composition dependent elastic modulus and phase stability of Ni2MnGa-based alloys by using a first-principles method, in hope of clarifying their connection to the properties of these alloys. In this article, we review the main results of our investigations. We show that the tetragonal shear modulus C' is a better predictor of the composition dependent T (M) than the number of valence electrons per atom (e/a) since the general T (M) similar to C' correlation works for some of the alloys for which the T (M) similar to e/a correlation fails, although there exist several cases for which both the general T (M) similar to C' and T (M)similar to e/a correlations break down. Employing the experimentally determined modulation function, the complex 5-layer modulated (5M) structure of the martensite of Ni2MnGa and the Al-doping effect on it are studied. We find that the shuffle and shear of the 5M structure are linearly coupled. The relative stability of the austenite and the martensites is examined by comparing their total energies. The non-modulated martensite beta aEuro(3)aEuro(2) with the tetragonality of the unit cell c/a > 1 is shown to be globally stable whereas the 5M martensite with c/a < 1 is metastable. The critical Al atomic fraction over which the martensitic transformation between the 5M martensite and austenite cannot occur is predicted to be 0.26, in reasonable agreement with experimental findings.","authors":[],"categoryName":"|","doi":"","fpage":"295","id":"68f072dd-757f-4f4e-b6d6-7e777f6db628","issue":"2","journal":{"abbrevTitle":"SCS","id":"8e02334e-0007-4675-9eda-1bc1d39b75d9","issnPpub":"1674-7321","publisherId":"SCS","title":"Science China-Technological Sciences"},"keywords":[{"id":"e57a06e8-2b98-4a72-b4b1-bddfd09df5cb","keyword":"Ni2MnGa;martensitic transformation;elastic modulus;phase stability;density functional theory;martensitic-transformation;magnetic-properties;heusler alloys;1st-principles investigations;crystal-structures;potential model;approximation;mechanics;behavior;strain","originalKeyword":"Ni2MnGa;martensitic transformation;elastic modulus;phase stability;density functional theory;martensitic-transformation;magnetic-properties;heusler alloys;1st-principles investigations;crystal-structures;potential model;approximation;mechanics;behavior;strain"}],"language":"en","publisherId":"1674-7321_2012_2_6","title":"Composition dependent elastic modulus and phase stability of Ni2MnGa based ferromagnetic shape memory alloys","volume":"55","year":"2012"},{"abstractinfo":"On the basis of the uniform design method, six kinds of martensitic hot work die steels were designed.

The influence of preparation technology on the structure and phase composition of the coating was investigated by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) analyses, and then their relationship was discussed. The results indicate that the Si/Mo ratio of the slurry and sintering processing were two main factors that significantly affected the structure and phase composition of the multi-coating. Appropriate sintering process and relatively high Si/Mo ratio were essential for preparing the multi-coating with dense structure and favorable phase composition. After being sintered at 1723 K for 2 h and with the Si/Mo ratio of the slurry being 4.5 (weight ratio), a dense structure accompanied by favorable phase composition of the coating can be obtained. When heat treated at 2373 K for 1 h, this coating became more compact and continuous. Oxidation tests (performed at 1623 and 1823 K) demonstrated that both of these two obtained multi-coatings exhibited better anti-oxidation property than single layer SiC coating.","authors":[{"authorName":"Xin Yang","id":"5f10853d-359d-4efb-bd7a-bddf44ecbbba","originalAuthorName":"Xin Yang"}],"categoryName":"|","doi":"","fpage":"106","id":"da15a2da-3b86-4cc2-9d3d-9a5e85326b67","issue":"2","journal":{"abbrevTitle":"CLKXJSY","coverImgSrc":"journal/img/cover/JMST.jpg","id":"11","issnPpub":"1005-0302 ","publisherId":"CLKXJSY","title":"材料科学技术(英文)"},"keywords":[{"id":"eb1dc8bd-e699-4252-89f6-99a339fba2c6","keyword":"Carbon/carbon composites","originalKeyword":"Carbon/carbon composites"},{"id":"8191fdbc-9921-4e36-8b60-b4b25b9ca95d","keyword":"null","originalKeyword":"null"},{"id":"674c1700-cca2-47b0-9894-1a45a950c817","keyword":"null","originalKeyword":"null"}],"language":"en","publisherId":"1005-0302_2010_2_12","title":"Influence of Preparation Technology on the Structure and Phase Composition of MoSi2-Mo5Si3/SiC Multi-coating for Carbon/Carbon Composites","volume":"26","year":"2010"},{"abstractinfo":"The Ni3B phase was formed when boron (0.5 at. pet B) was added to the intermetallic of stoichiometric and off-stoichiometric (Ni-24 at. pct Al) compounds.
