Abstract
This study examines the influence of ZrO₂ on austenitic stainless steel 316 (ASS 316). Following the addition of varying weight percentages (0, 1, 2, and 3) of ZrO₂ to ASS 316 powder, the samples were ball-milled for a duration of 30 h and then subjected to vacuum hot-pressing (VHP) for..... More

Effect of MgO Addition on the Monoclinic to Tetragonal Transition of ZrO₂ 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.....
