Temperature and load-ratio dependent fatigue-crack growth in the CrMnFeCoNi high-entropy alloy [PDF]
, 2019 Multiple-principal element alloys known as high-entropy alloys have rapidly been gaining attention for the vast variety of compositions and potential combinations of properties that remain to be explored. Of these alloys, one of the earliest, the ‘Cantor

Relationship between microstructure and fracture types in a UNS S32205 duplex stainless steel
Materials Research, 2013 Duplex stainless steels are susceptible to the formation of sigma phase at high temperature which could potentially be responsible for catastrophic service failure of components.

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...

Correlation of processing and sintering variables with the strength and radiography of silicon nitride [PDF]
A sintered Si3N4-SiO2-Y2O3 composition, NASA 6Y, was developed that reached four-point flexural average strength/standard deviation values of 857/36, 544/33, and 462/59 MPa at room temperature, 1200 and 1370 C respectively.

Journal of Prosthodontics, EarlyView.Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.
