EXPERIMENTAL INVESTIGATIONS OF THE BEHAVIOR OF BRITTLE MATERIALS AT VARIOUS RANGES OF TEMPERATURE.
Abstract
Young's modulus, the fracture stress and the fracture strain (strain at fracture) of Alumina (Al2O3) were determined in a temperature range from -200C to 1200C by bending tests and the influence of the porosity, the grain size, the strain rate, the specimen diameter and length on these quantities was investigated. The bending tests were also extended in the same temperature range to other oxide ceramic materials like Magnesia (MgO), Zirconia (ZrO2) and Spinel (Al2O3 . MgO). Temperature treatments were undertaken on Alumina specimens in the temperature range from 1000C to 1600C and the change of the porosity and the grain size was observed. Bending tests were carried out for the determination of Young's modulus for tension and compression. (Author)
