There is a need for methods that can help predict and avoid fatigue failures of silicon nitride ceramic components. The fatigue threshold R-curve has been proposed as potential solution to this problem. In this study, the fatigue threshold R-curve fo

The strength-normalized fatigue endurance strength of the bulk metallic glass (BMG) Zr52.5Cu17.9Ni14.6Al10Ti5 (Vitreloy 105) has been reported to be the highest for any BMG; however, to date, there has been no explanation of why this material is so m

The role of microstructure in affecting the fatigue crack growth resistance of grain bridging silicon nitride ceramics doped with rare earth (RE = Y, La, Lu) oxide sintering additives was investigated. Three silicon nitride ceramics were prepared usi

Crack bridging is an important source of crack propagation resistance in many materials and the bridging stress distribution as a function of crack opening displacement is widely believed to represent a true material property uninfluenced by sample g

Silicon nitride ceramics doped with rare-earth oxides exhibit excellent hardness, toughness, and strength at elevated temperatures making them attractive materials for replacing cemented carbides in a variety of manufacturing applications such as cut
