Impact toughness and fracture toughness
Witryna摘要: Different contents of Ni(0.3wt.%to 1.2wt.%)were added to the QT400-18L ductile iron to investigate the effect of Ni addition on the impact toughness of cast ductile irons at low temperatures.The impact toughnesses of the samples at room and low temperatures were tested.The microstructures and fractographs were … WitrynaSo the calculation results aren't in accordance with the test results. First, thickness effect on fracture toughness and plastic zone size is analyzed. Then using the relation of …

WitrynaFracture toughness is measured using three-point bending. Fracture paths are studied using micro- X-ray computed tomography. The effects of ceramic filler volume fraction and size on the fracture toughness and fracture mechanisms are studied. Furthermore, the implications are discussed for designing robust composite materials. WitrynaIn general austempering resulted in lower hardness values when compared to quenching and tempering but higher impact toughness. The wear resistance was best for …
