  摘要：

  摘要 已经在 RE-Mg-N（RE=La、Ce、Gd）系统中进行了实验，以探索使用 Mg 作为反应熔体合成氮化物的可能性，并扩展已知的含 Mg 氮化物化合物的数量。由于这些实验仅产生二元氮化物，我们探索了混合 Na/Mg 熔体的使用，并发现了四元氮化物 BaMg 3.33 Nb 0.67 N 4 ( 1 )、BaMg 3.33 Ta 0.67 N 4 ( 2 ) 和 Eu 4 TaMgN 5 ( 3 ) ，通过单晶结构分析表征。BaMg 3.33 M 0.67 N 4 化合物与 UCr 4 C 4 同型 [RK Behrens, W.

• TEM study of real precipitation behavior of an Mg–0.5at%Ce age-hardened alloy
  作者：Kaichi Saito、Hiroshi Kaneki

  日期：2013.10

  Precipitates formed in an Mg-0.5at%Ce alloy during age-hardening at certain temperatures ranging between 180 degrees C and 250 degrees C have been thoroughly investigated by a combined technique of TEM and HAADF-STEM. The precipitation sequence can be presented as Mg-solid solution -> GP-zone -> beta(1) (Mg-3-Ce; BiF3-type) -> beta (Mg12Ce; Mn12Th-type). At an early stage of aging (180 degrees C for 2 h), fine precipitates of planar GP-zone with an ordered structure appear in parallel to (100)(m) planes of the Mg-matrix, having a thickness of sub-nm and an extension of 5-15 nm. With an advance of aging, the GP-zones increasingly grow larger and combine with the neighbors. When the GP-zones have reached as large as approximately 20 nm in diameter, the age-hardening effect is maximized (180 degrees C for 70 h). After the top-aging, the GP-zones begin to decompose and disappear, and instead precipitates of two other phases, i.e. the beta(1)- and the beta-phase come into sight in the matrix with definite crystallographic orientation relations of [0 0 1](m)// [1 1 0](beta 1)//[1 0 0](beta) and (1 1 0)(m)//(1 1 1)(beta 1)//(0 1 0)(beta), finally completing the aging effect with full of coarse beta-precipitates.

• Oxidation resistance of B2 rare earth–magnesium intermetallic compounds
  作者：B. Stumphy、Y. Mudryk、A. Russell、D. Herman、K. Gschneidner

  日期：2008.7

  The oxidation behaviors of YMg and CeMg were rneasured in flowing air using the thermal gravimetric analysis technique. Negligible oxidation is observed at room temperature in both compounds. At elevated temperatures, the rare earth metals oxidize preferentially, while the underlying materials transform into Mg-rich intermetallics before the Mg oxidizes to MgO. The oxidation resistance of YMg is several orders of magnitude greater than that of CeMg. The oxidation of YMg follows parabolic kinetics with an activation energy of 104 kJ/mol while that of CeMg obeys a linear law with an activation energy of 136 kJ/mol. (C) 2007 Elsevier B.V.
