主 题:MgO-C refractory Stainless steel fiber Thermal shock resistance Oxidation resistance Microstructure
摘 要:MgO-C refractories with stainless steel fibers were prepared to investigate the effects of stainless steel fibers addition on the thermal shock resistance,oxidation resistance,and microstructure of MgO-C refractories,and the optimum amount of stainless steel fibers was *** results showed that adding stainless steel fiber in MgO-C refractories can increase flexural strength and thermal shock resistance,with an optimal addition of 2 wt.%,owing to the bridging effect and crack deflection toughening of stainless steel fibers inside the *** formation of MgAl1.9Fe0.1O4 composite spinel,which was responsible for higher oxidation resistance,produced volume expansion and prevented the diffusion of *** strengthening mechanism is physical embedding at room temperature,while it is reaction bonding at high temperature.
