Selective laser melting has been used to demonstrate the striking effect of scanning strategies on crystalline texture in 316L SS. The aligned crystal orientation along tensile direction (Z-axis) could be varied using strategy. A strong 〈100〉 single crystalline-like is obtained scan and a 〈110〉 was observed build when bidirectional without rotation. Fiber bi-directional vectors were rotated by 67° (Rot-scan) for each layer. study highlights correlation between with resulting textures,...
We present experimental data showing that the equiatomic CrMnFeCoNi high-entropy alloy undergoes two magnetic transformations at temperatures below 100 K while maintaining its fcc structure down to 3 K. The first transition, paramagnetic spin glass, was detected 93 and second transition of ferromagnetic type occurred 38 Field-assisted cooling resulted in a systematic vertical shift hysteresis curves. Strength direction associated magnetization bias proportional strength field shows linear...

Solution-annealed AISI 316L steel was fatigued with constant plastic strain amplitudes at room temperature and under various conditions depressed temperatures down to 113 K reveal its stability against deformation-induced martensite formation. Microstructural changes induced by fatigue were characterized transmission electron microscopy (TEM), channeling contrast imaging (ECCI) backscattering diffraction (EBSD) techniques. Neutron magnetic induction method adopted for quantification of...
Graphene based carbon materials have attracted a great deal of attention in the last decade; nowadays tons graphene are produced yearly. However, there is lack precise and reliable techniques for determination structural properties on bulk scale. The analytical methods being routinely applied characterization, including TEM AFM, can be only used study scant amounts samples do not give general information average number layers structure prepared graphenes. On other hand, diffraction...
High voltage spinel is one of the most promising next-generation cobalt-free cathode materials for lithium ion battery applications. Besides typically utilized compositional range LixNi0.5Mn1.5O4 0 < x 1 in window 4.90-3.00 V, additional 1.5 mol Li per formula unit can be introduced into structure, an extended to 1.50 V. Theoretically, this leads significant increase specific energy from 690 1190 Wh/kg. However, utilization potential rapid capacity fading and polarization that lack a...

Due to their superb mechanical properties and high specific mass, tungsten heavy alloys are used in demanding applications, such as kinetic penetrators, gyroscope rotors, or radiation shielding. However, structure, consisting of hard particles embedded a soft matrix, makes the deformation processing challenging task. This study focused on characterization behavior during thermomechanical WNiCo alloy (THA) via method rotary swaging at various temperatures. Emphasis is given microstrain...
In cluster-based quasicrystals, tetrahedra located in conventional Tsai clusters may be replaced by single rare-earth $(R)$ ions at the cluster centers (pseudo-Tsai clusters). this study, we investigate effect of pseudo-Tsai incorporation on magnetic structures two approximants, Tsai-type Tb-Au-Si [denoted TAS(0)] and Ho-Au-Si HAS(52)] with partial replacement clusters, up to 52%. The mixture can considered a different source randomness/disorder other than chemical mix sites (Au/Si). latter...
The atomic and magnetic structure of the 1/1 Tb(14)Au(70)Si(16) quasicrystal approximant has been solved by combining x-ray neutron diffraction data. is classified as a Tsai-type with certain structural deviations from prototype structures; there are additional positions in so-called cubic interstices well cluster centers. property measurements indicate to be ferrimagnetic-like below 9 K contrast related Gd(14)Au(70)Si(16) that reported purely ferromagnetic.
Knowledge of texture and residual stresses in tungsten heavy pseudoalloys is substantial for the microstructure optimization. These characteristics were determined cold warm rotary swaged W/NiCo composite with help neutron diffraction.
