Effect of MgO Addition on the Monoclinic to Tetragonal Transition of ZrO<sub>2</sub> Fabricated by High Energy Ball Milling
Ashutosh Sharma, Byungmin Ahn
Korean J. Met. Mater. 2018;56(10):718-726.   Published online 2018 Oct 5
DOI: https://doi.org/10.3365/KJMM.2018.56.10.718

Abstract
In this work, we studied the formation of partially stabilized zirconia by a high energy ball milling (HEBM) approach. Zirconia powder was mixed with 8 mol% MgO and the powder mixture was milled for 10 hours. The structural and morphological evolutions of the powder particles were studied using X-ray diffraction.....

Korean J. Met. Mater. 2017;55(11):783-789.   Published online 2017 Oct 31
DOI: https://doi.org/10.3365/KJMM.2017.55.11.783

Abstract
In this study, planetary ball milled WC-5 wt%Co powders were sintered using the pulsed current activated sintering (PCAS) process. With this process, fully densified hard materials were obtained in a shorter time than conventional processes such as a HP and HIP. The particle sizes of the planetary ball milled WC.....
