Identification of thin plates seen in R5(SixGe1-x)4 alloys, where R is Gd, Tb, Dy, and Er

Rs(SixGe1-x)4 alloys, where R is Tb, Dy, and Er, have been examined. Their microstructures consisted of large grains with thin plates of a second phase. Energy dispersive spectrometry of the plates revealed a rare earth rich composition. It is proposed that the plates are R5(Si,Ge1-X)3 compounds, si...

Description
Summary:Rs(SixGe1-x)4 alloys, where R is Tb, Dy, and Er, have been examined. Their microstructures consisted of large grains with thin plates of a second phase. Energy dispersive spectrometry of the plates revealed a rare earth rich composition. It is proposed that the plates are R5(Si,Ge1-X)3 compounds, similar to results seen in Gds(Si,Ge1-X)4.
