抄録

The Ti-rich region of the Ge–Si–Ti ternary isotherm at 900°C was determined by metallography, X-ray diffraction, and electron microprobe analysis. The sample alloys were prepared by arc-melting. It was confirmed that at 900°C Ti<SUB>5</SUB>Si<SUB>3</SUB> and Ti<SUB>5</SUB>Ge<SUB>3</SUB> form a continuous solid solution Ti<SUB>5</SUB>(Si<SUB>1−<I>x</I></SUB>Ge<I><SUB>x</SUB></I>)<SUB>3</SUB> with the hP16 crystal structure. The lattice constants for Ti<SUB>5</SUB>(Si<SUB>1−<I>x</I></SUB>Ge<I><SUB>x</SUB></I>)<SUB>3</SUB> are linear functions of the composition variable <I>x</I>. This continuous solid solution also exists at 1100°C. There is another solid solution Ti<SUB>3</SUB>(Si<SUB>1−<I>y</I></SUB>Ge<I><SUB>y</SUB></I>), that has the same crystal structure as Ti<SUB>3</SUB>Si (tP32), but this solid solution is stable only for <I>y</I>≤0.44 at 900°C. It was also shown that there is not any other binary or ternary phase within the Ti–Ti<SUB>5</SUB>Si<SUB>3</SUB>–Ti<SUB>5</SUB>Ge<SUB>3</SUB> triangular region except Ti<SUB>5</SUB>(Si<SUB>1−<I>x</I></SUB>Ge<I><SUB>x</SUB></I>)<SUB>3</SUB> and Ti<SUB>3</SUB>(Si<SUB>1−<I>y</I></SUB>Ge<I><SUB>y</SUB></I>). In this region, there is one three-phase field Ti+Ti<SUB>5</SUB>(Si<SUB>1−<I>x</I></SUB>Ge<I><SUB>x</SUB></I>)<SUB>3</SUB>+Ti<SUB>3</SUB>(Si<SUB>1−<I>y</I></SUB>Ge<I><SUB>y</SUB></I>), and the compositions of these three phases are Ti<SUB>0.96</SUB>Si<SUB>0.03</SUB>Ge<SUB>0.01</SUB>, Ti<SUB>0.63</SUB>Si<SUB>0.08</SUB>Ge<SUB>0.29</SUB>, and Ti<SUB>0.75</SUB>Si<SUB>0.14</SUB>Ge<SUB>0.11</SUB> respectively. In addition, there are three two-phase fields within this region: Ti<SUB>5</SUB>(Si<SUB>1−<I>x</I></SUB>Ge<I><SUB>x</SUB></I>)<SUB>3</SUB>+Ti<SUB>3</SUB>(Si<SUB>1−<I>y</I></SUB>Ge<I><SUB>y</SUB></I>), Ti+Ti<SUB>3</SUB>(Si<SUB>1−<I>y</I></SUB>Ge<I><SUB>y</SUB></I>), and Ti+Ti<SUB>5</SUB>(Si<SUB>1−<I>x</I></SUB>Ge<I><SUB>x</SUB></I>)<SUB>3</SUB>.
