2002年8月1日 · Single-phase alloys consisting of the ZrCr 2 Laves were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and density measurement. The XRD using Ni-filtrated Cu K α radiation was performed on powdered samples with mesh No. 200, which contain Si powder as a standard reference.

ZrCr2 is Hexagonal Laves-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 12-coordinate geometry to four Zr and twelve Cr atoms.

2025年1月1日 · Experimental findings demonstrate that Sn notably inhibits ZrCr 2 formation, resulting in a reduction of ZrCr 2 approximately 10%. However, Zn and Mg do not exhibit a substantial inhibitory effect on ZrCr 2 due to their low yield …

The elaboration of LaZr2Cr4Ni5-based intermetallic compound was performed by mechanical alloying from LaNi5 and ZrCr2 precursors and characterized as active materials of negative electrodes in...

2024年10月15日 · The polymorph stability of the ZrCr 2 Laves phases was examined by diffraction techniques using powder XRD and EBSD for various as-cast and heat-treated samples. The results show unambiguously a direct transition between C14 and C15 forms without the C36 as intermediate phase.
