Prediction of crack growth in a nickel-based superalloy under fatigue-oxidation conditions
Prediction of oxidation-assisted crack growth has been carried out for a nickel-based superalloy at elevated temperature based on finite element analyses of oxygen diffusion, coupled with viscoplastic deformation, near a fatigue crack tip. The material constitutive behaviour, implemented in the finite element code ABAQUS via a user-defined material subroutine (UMAT), was described by a unified ...
متن کاملCyclic oxidation behavior of uncoated and aluminum-rich nickel aluminide coated Rene-80 superalloy
In this study, aluminide coating was employed to enhance the high-temperature cyclic oxidation of Rene-80 superalloy at 950ºC. The microstructural aspects and phase constituents of samples were investigated with scanning electron microscopy (SEM) and x-ray diffraction (XRD) techniques. The result of oxidation tests showed that the weight gain in the uncoated sample was considerably higher than...
متن کاملModeling of human calvarium under static loading
There are many papers on head modeling in literature [1]. Generally, the topic of most of them is designing and modeling devices for head (especially brain) protection, e.g. helmets. On the other side, most papers are about modeling of whole part of top body (a torso and a head). The main aim of these researches is simulation of the backbone behavior under external load applied to the head. The...
متن کاملLaser Cladding of Ultra-Thin Nickel-Based Superalloy Sheets
Laser cladding is a well-established process to apply coatings on metals. However, on substrates considerably thinner than 1 mm it is only rarely described in the literature. In this work 200 µm thin sheets of nickel-based superalloy 718 are coated with a powder of a cobalt-based alloy, Co-28Cr-9W-1.5Si, by laser cladding. The process window is very narrow, therefore, a precisely controlled Yb ...
