时Ti.(50一x)Mn—t0Cr-xV(x=O,8.j2,t6,20,24,28,32)合金的研究表明,随着 合金中v含量的增加,台金由C14 Laves相变为C14 Laves相与BCC相共存,再变 为单一的BCC相结构。V含量的增加导致合金的吸氢容量增加、吸放氢平台变得平 坦、平台压力降低以及放氢过程中合金中残余氢容量增加。BCC相合金吸氢过程会...
Single-crystal micropillar specimens of a hexagonal Laves phase (Fe,Ni)2Nb, produced by focused ion beam milling, demonstrated plastic deformation in compression at room temperature by slip. Specifically, if dislocation sources are introduced in the pillars, or are previously present, plastic ...

We measured the thermal expansion and the specific heat of Ti<italic>x</italic>Fe100-x alloys with <italic>x = 30.5</italic>, 32.5 and 35, all with hexagonal C14 laves phase structure (MgZn2) like TiFe2, and determine the
Magnetic properties of metastable C14-RMn2 Laves phase (R Y, Gd, Tb, Dy and Yb), have been measured. YMn2 and YbMn2 are paramagnetic down to 4.2 K. GdMn2, TbMn2 and DyMn2 are ferromagnetic at low temperatures and the temperature dependence of their susceptibilities obeys the Curie-Weiss...
Phase Equilibria in the Ternary Nb-Cr-Al System and Site Occupation in the Hexagonal C14 Laves Phase Nb(AlxCr1-x)2 The ternary Nb-Cr-Al phase diagram exhibits extended phase fields of the cubic C15 and the hexagonal C14 Laves phases Nb(AlxCr1-x)2. A number of Nb-Cr-Al a... O ...
Assessment of off-stoichiometric Zr33-xFe52+xSi15 C14 Laves phase compounds as permanent magnet materials Recently, Fe-based rare-earth-free compounds with non-cubic crystal structures were proposed as a base for permanent magnets which would not rely on critic... AM Gabay,GC Hadjipanayis - ...
Phase stabilityElastic propertiesAnisotropyElectronic structuresThe structural and mechanical properties, Debye temperatures and anisotropic sound velocities of the Laves phases AlM (M=Mg, Ca, Sr and Ba) with C14-type structure were investigated using the first-principles corresponding calculations. The ...
Especially, C14 Laves phase Mg2Ca alloy as an excellent strengthening phase has been the research focus in Mg–Ca alloy. So far, numerous theoretical and experimental investigations of mechanical, electronic and thermodynamic properties of Mg2Ca Laves phase have been performed [9], [10], [11],...
