説明
The behavior of tetragonal (t)-monoclinic (m) transformation in partially stabilized zirconia (PSZ) containing yttria from 0 to 6 mol% was investigated by means of dilatometry. The results are as follows:<BR>(1) The transformation temperature (T0m−t) decreases lineally with increasing Y2O3 content. The present data almost coincide with the result by Ruh et al..<BR>(2) By using the relationship between T0m−t and Y2O3 mol% as a conversion curve, the equilibrium concentration of t-phase in alloys annealed at 1600°C (1873 K), 1700°C (1973 K) and 1800°C (2073 K) was determined from their T0m−t, and it was found that the solubility limit of Y2O3 in t-phase increased with rising temperature.<BR>(3) The as-annealed PSZ was composed of (t+c) phases, but the m\ ightleftharpoonst transformation took place more and more easily by cyclic heating. These transformations can proceed isothermally with release of the transformation-induced internal stress by the aid of slow speed cracking.<BR>(4) The t\ ightharpoonupm transformation is suppressed by rapid cooling, but the m\ ightharpoonupt transformation is not much affected by the heating rate.
