摘要：

Single crystals of 24-32 mol% yttria fully stabilised cubic zirconia have been deformed in compression along (112) at T = 1400-1500 degreesC with strain rates ranging from similar to10(-1) to similar to10(-4) s(-1) (nominal stresses 100-320 MPa). The deformation mechanisms are discussed in terms of macroscopical and microscopical parameters. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
