Abstract

The thermal expansion coefficients for Si3Zr5, Si3Ti5 and Si3Ti2Zr3 intermetallic silicides of 16H-type crystal structure have been measured using high-temperature X-ray powder diffraction. The anisotropy of the thermal expansion coefficients of Si3Ti2Zr3 is lower than that of Si3Zr5 and Si3Ti5. Si3Ti2Zr3 is formed by substituting an entire layer of zirconium atoms by a layer of titanium atoms in Si3Zr5. This substitution of elements reduces the thermal expansion anisotropy of 16H-type intermetallic silicides. The thermal expansion of Si3Ti2Zr3 is reduced along the c-axis and increased along the a-axis, compared with those of Si3Zr5 and Si3Ti5. Si3Ti2Zr3 with low anisotropy of thermal expansion can he used for structural applications at ultra-high temperatures. Copyright (C) 1996 Elsevier Science Ltd.
