Abstract of the dataset | This study investigates the thermo-mechanical behaviour of steel-ceramic composites based on a matrix of austenitic stainless steel and coarse-grained magnesia particles. Composites reinforced with fresh-fused magnesia particles were compared to those reinforced with recycled magnesia sourced from spent MgO-C refractory lining bricks. The volume fraction of recycled magnesia varied from 20 vol% to 40 vol%. Quasi-static compression tests were performed at room temperature and within a temperature range of 800 ◦C–1100 ◦C. Results showed that incorporating coarse-grained ceramic reinforcements into the steel matrix increased the compressive strength at all temperatures. The composite reinforced with recycled magnesia demonstrated superior mechanical properties over the variant with fresh-fused magnesia due to a smaller and more uniform particle size distribution resulting from crushing steps in the recycling process. Although non-metallic inclusions from contaminated zones of the refractory bricks were present in the recycled powder, they did not affect the overall damage mechanisms. | |

Project abstract | The subproject P12 investigates the thermo-mechanical properties of austenitic stainless-steel composites reinforced with coarse-grained, recycled magnesia particles. The magnesia particles are derived from spent carbon-bonded refractory bricks. Their ability to reinforce the matrix is compared with fresh magnesia particles of the same sieve size. | |
