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 … Witryna28 wrz 2024 · For structural components, strength and fracture toughness are two important mechanical properties. As tensile strength increases, the amount of stress a metal can support without cracking and fracturing increases. And as fracture toughness increases, the energy required to cause a crack to grow to fracture increases. …
Witryna1 cze 2024 · The influence of temperature on impact and fracture toughness values in different regions of a welded joint is analysed for low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. Standard Charpy specimens were tested on instrumented pendulum to separate total impact energy into energy for initiation and … Witryna7 kwi 2004 · THe fracture toughness at instability, J C, was also computed and plotted against the amount of stable crack growth in order to construct J-R curves as a function of size and strain rate. From these curves an alternative critical fracture parameter, K JIC, was calculated. Weibull statistics were used as a tentative approach for treating …
