Improvement of mechanical properties of zirconia-toughened alumina by sinter forging [PDF]

, 1994
ZTA powder with a composition of 85 wt% alumina/15 wt% zirconia was prepared by a gel precipitation method. Sinter forging was performed with this powder to enhance the mechanical properties of ZTA materials.

Model of fracture micro mechanism of Cu-Cr-Zr system by in-situ tensile test in SEM [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2003
In the present work fracture mechanism of the Cu-Cr-Zr system was studied by "in-situ tensile test in SEM". It has been shown, that during tensile strain over the critical deformation the first cracks appeared due to the decohesion of matrix - large Cr ...

Effect of Li Content on the Microstructure and Mechanical Properties of as-Homogenized Mg-Li-Al-Zn-Zr Alloys

Alloys, 2023
The microstructure and mechanical properties of as-homogenized Mg-xLi-3Al-2Zn-0.2Zr alloys (x = 5, 7, 8, 9, 11 wt.%) were studied. As the Li content increased from 5 wt.% to 11 wt.%, the alloy matrix changed from the α-Mg single-phase to α-Mg+β-Li dual ...
