Tensile strength of MgO-graphite based refractories: Effect of anisotropy and specimen size

Oxide-graphite refractories represent the new paradigm of materials for extreme environments since 1970's: materials that resist thanks to “in situ” microstructural changes. The analysis of post-mortem linings necessitates the use of small specimens because main microstructural changes occur wi...
