Název v původním jazyce

Strain Measurement of a Ductile Composite Al.sub.2./sub.O.sub.3./sub./Y.sub.3./sub.Al.sub.5./sub.O.sub.12./sub.(YAG) by Neutron Diffraction.

Popis výsledku v původním jazyce

Strain measurement of an unidirectionally solidified single-crystal Al.sub.2./sub.O.sub.3./sub. / single crystal Y.sub.3./sub.Al.sub.5./sub.O.sub.12./sub. (YAG) eutectic composite was performed by neutron diffraction technique using two-axis crystal diffractometer with one-dimensional position sensitive detector. Microstructure of this composite shows a formation of a compatible interface with no amorphous phase region among the two-phase grain boundaries. This fact causes excellent characteristics on high-temperature tensile and flexural strengths in the range of 350 - 400 MPa from the room temperature up to 2073 K (just below its melting point of about 2100 K) with no apparent temperature dependence. The neutron diffraction measurements were carriedout to measure residual strains of the two phases in the composite, together with the sintered speciment of Al.sub.2./sub.O.sub.3./sub. and YAG as the reference materials, respectively. The YAG phase strains for three crystal lattice plan
