Superplastic deformation and high temperature load relaxation behavior of coarse-grained iron aluminides with the composition of Fe-28 at.% Al have been investigated. A series of load relaxation and tensile tests were conducted at temperatures ranging from 600 to 850C. The flow curves obtained from load relaxation tests were found to have a sigmoidal shape and to exhibit stress vs. strain rate ...

A new method for the simulation of evolving multi-domains problems has been introduced in previous works (RealIMotion), Florez et al. (2020) and further developed parallel context isotropic Grain Growth (GG) with no consideration effects Stored Energy (SE) due to dislocations. The methodology consists a front-tracking approach where one originality is that not only interfaces between grains are...

In this work, the microstructural evolutions and mechanical properties of an as-cast Mg-10Gd-4Y-1.5Zn-0.5Zr (wt %) alloy during successive multi-pass equal channel angular pressing (ECAP) were systematically investigated by X-ray diffractometer, scanning electron microscopy, transmission electron microscopy, and compression test. The obtained results show that the microstructure of as-cast allo...

The wear and rolling contact fatigue (RCF) performance of eutectoid hypereutectoid rail steels were studied. Subsequently, the microstructure evolutions subsurface materials these two after testing comparatively investigated. results indicated that, compared with rail, had lower loss, but longer RCF crack lengths. After rolling-sliding testing, original equiaxed undeformed coarse grains rails i...

In this work, the hot forging behavior of a dual phase stainless steel in temperature range 850–1250 °C was investigated. The study revealed occurrence significant cracking phenomenon for processing temperatures below 950 that attributed to combined effect intermetallic precipitation and severe deformation. EBSD examination highlighted continuous dynamic recrystallization both ferrite austenite...
