Additive manufacturing (AM) of brittle materials remains challenging, as they are prone to cracking due to the steep thermal gradients present during melting and cooling after laser exposition. Silicon is an ideal brittle material for study since mos

Mesoporous submicron α−Al2O3 green compacts were fabricated using slip casting of ultrafine alumina powders. The pre-sintered samples were sintered in air atmosphere at 1300 °C, 1350 °C, 1400 °C, and 1500 °C to obtain a variety of grain morpho

The failure mechanism known as scuffing is a major problem in lubricated sliding mechanical components, specifically for those tribological systems working under starved lubrication conditions. It occurs suddenly and often results in loss of componen
