SPIN REORIENTATION PHENOMENA IN SUBSTITUTED Pr2 (Co, Fe)17 INTERMETALLICS
The magnetic anisotropy phase diagrams of Pr2Co17-,Fen and Pr2Co17-,Fez-,Ty (T=Mn, Zr, Ti, Hf) compounds have been determined. Two spin reorientation temperatures, TSr1 and Tsr2, have been observed. Near the Ts,l or Ts,2 boundary the anisotropy is conical; between the two spin reorientation temperatures they exhibit uniaxial anisotropy and beyond these limits they are planar. Introduction --0-y...
متن کاملModification of Primary Si Crystals and Fe-rich Intermetallics in LM28 Al Alloy Fabricated Through Thixoforming
In the present research, thixoforming route was carried out in order to enhance the microstructural features of LM28 piston alloy. Typical microstructure of this alloy was composed of coarse, polygonal primary silicon particles, eutectic matrix and intermetallic phases. Thermal analysis was carried out to study the solidification path of the base alloy and determine the major arrest temperature...
متن کاملIn situ quantification of the nucleation and growth of Fe-rich intermetallics during Al alloy solidification
Real-time in situ synchrotron X-ray tomographic microscopy was used to gain new insights into and quantify the nucleation mechanisms and growth kinetics of b-Al5FeSi intermetallics during solidification of an aluminium Al–7.5Si–3.5Cu–0.6Fe (wt.%) alloy. Three new insights were obtained. First, the plate-like b-intermetallics appeared to nucleate mainly on or near the primary aluminium dendrites...
متن کاملEffect of Mn and Fe on the Formation of Fe- and Mn-Rich Intermetallics in Al–5Mg–Mn Alloys Solidified Under Near-Rapid Cooling
Mn was an important alloying element used in Al-Mg-Mn alloys. However, it had to be limited to a low level (<1.0 wt %) to avoid the formation of coarse intermetallics. In order to take full advantage of the benefits of Mn, research was carried out to investigate the possibility of increasing the content of Mn by studying the effect of cooling rate on the formation of Fe- and Mn-rich intermetall...
متن کاملMagnesium - rich Intermetallics RE
The magnesium-rich intermetallic phases RE3RuMg7 (RE = Y, Nd, Dy, Ho) have been synthesized from the elements in sealed niobium ampoules and subsequently characterized by powder X-ray diffraction. The structure of the dysprosium compound was refined on the basis of single-crystal X-ray diffractometer data: Ti6Sn5 type, P63/mmc, a = 1019.1(2), c = 606.76(9) pm, wR2 = 0.0159, 439 F2 values, 19 va...
