网页2010年2月26日 · Abstract. Superplastic deformation of a fully dense TZ3Y material, having a starting grain size around 135–145 nm and depleted of any amorphous phase at grain boundaries, has been investigated using compressive creep tests in air in the temperature range of 1100°–1300°C and the real stress range of 50–100 MPa.
Robust synthesis of yttria stabilized tetragonal zirconia powders (3Y ...
网页2013年7月15日 · A semi-continuous PCA process (Precipitation with Compressed Anti-solvent) coupled with sol–gel reactions has been developed in this work for the synthesis of yttria-stabilized tetragonal zirconia powders (3Y-TZPs) with controlled morphology, structure and microstructure.
Superplastic deep drawing of tetragonal zirconia ceramics at 1160°C
网页1998年12月1日 · Superplastic forming under biaxial tension of tetragonal zirconia (Y-TZP) is investigated by pushing a hemispherical punch (radius 6 mm) on Y-TZP which was placed on a ring with an inner diameter of 16·7 mm. Dense Y-TZP samples with a grain diameter of 125 nm could be elongated to a dome height of at least 8 …
