In this study the effects on resistance to corrosion of a low alloy steel after plasma nitriding has been reported. Nitriding was performed at temperature 450 °C and also 520 for same duration 10 h in nitrogen hydrogen (80:20) gas mixture. Sample holder biased −250 V working pressure kept around 500 Pa. After samples along with bare were exposed X-ray diffraction (XRD) understand phase formatio...

In this study we present a series of light-weight (6.24 to 6.42 g/cm3), Ti-rich Mo-Si-Ti alloys (?40 at.% nominal Ti content) with the hitherto best combination pesting and creep resistance at 800 1200 °C, respectively. This has been achieved by fine-scaled eutectic-eutectoid microstructures substantial fractions primarily solidified (Mo,Ti)5Si3. (Mo,Ti)5Si3 was found be oxidation-resistant in ...

The synthesis of new substituted cobalt Phthalocyanine (CoPc) was carried out using starting materials Naphthalene-1,4,5, tetracarbonic acid dianhydride (NDI) employing dry process method. Metal oxides (MO) alloy (60%Ni3O4 40%-Co3O4 ) have been functionalized with multiwall carbon nanotubes (F-MWCNTs) to produce (F-MWCNTs/MO) nanocomposite (E2) and mixed CoPc yield (F-MWCNT/CoPc/MO) (E3). These...

In this study, α+β Ti-Al-V-Mo-Nb alloys with the addition of multiple elements that are suitable for laser additive manufacturing (LAM) were designed according to a Ti-6Al-4V cluster formula. This formula can be expressed as 12[Al-Ti12](AlTi2)+5[Al-Ti14]((Mo, V, Nb)2Ti), in which Mo and Nb added into partially instead V give nominal compositions Ti-6.01Al-3.13V-1.43Nb, Ti-5.97Al-2.33V-2.93Mo, T...

The data presented in this paper are related to the research article entitled "Theoretical stability and materials synthesis of a chemically ordered MAX phase, Mo2ScAlC2, and its two-dimensional derivate Mo2ScC" (Meshkian et al. 2017) [1]. This paper describes theoretical phase stability calculations of the MAX phase alloy MoxSc3-xAlC2 (x=0, 1, 2, 3), including chemical disorder and out-of-plan...

The usefulness of stochastic algorithms to retrieve the exit-plane wave function from periodic high-resolution electron microscopic images is investigated. In contrast to “classical” focal series reconstruction methods which need approximately twenty input images, fully non-linear reconstructions of periodic wave functions are possible in most cases from only two images using stochastic algorit...

Amorphous complexions have recently been demonstrated to simultaneously enhance the ductility and stability of certain nanocrystalline alloys. In this study, three quinary alloys (Cu–Zr–Hf–Mo–Nb, Cu–Zr–Hf–Nb–Ti, Cu–Zr–Hf–Mo–W) are studied test hypothesis that increasing chemical complexity grain boundaries will result in thicker amorphous further stabilize a microstructure. Significant boundary...

The formation of stress-induced α′′ martensite in a metastable β Ti-Mo-based alloy has been studied using X-ray diffraction and transmission electron microscopy. The martensite nucleates heterogeneously at pre-existing sub-grain boundaries by dissociation of the boundary dislocations which bow out on inclined planes. The growth of martensite laths from the resultant stacking faults occurs by th...

In this study, a high energy planetary ball milling technique was used to synthesize nano-crystalline Mo-Cu alloys. Molybdenum trioxide (MoO3) and copper oxide (CuO) were used as the starting materials. Carbo-thermal co-reduction of mixed Mo and Cu oxides powders was done with milling followed by a heat treatment at a high temperature. Differential thermal analysis/thermogravimetric (DTA/TG) wa...
