High entropy alloys (HEAs), offering a multi-dimensional compositional space, provide almost limitless design opportunities surpassing the frontiers of structural materials development. However, an in-depth appraisal fundamental physics behind strengthening in HEAs is essential order to leverage them achieve greater flexibility application oriented design. This viewpoint paper concentrates on issues regarding inherent fluctuations and corresponding impact highlighted. In particular, metal...
Optimum formulation of Biological-E's protein subunit CORBEVAX™ vaccine was selected in phase-1 and -2 studies found to be safe immunogenic healthy adult population. This is a phase-3 prospective, single-blinded, randomized, active controlled study conducted at 18 sites across India 18–80 year-old subjects. has two groups; (i) immunogenicity-group, participants randomized either (n = 319) or COVISHIELD™ arms 320). (ii) Safety-group containing single arm 1500) randomization not applicable....
High-performance ultra-lean binary Mg–Ca alloys are engineered by intelligent alloying and thermo-mechanical processing using hot-extrusion. With Ca-alloying contents as low 0.2-0.6 wt.%, remarkable room-temperature tensile properties obtained with strength values high 380–420 MPa, or ductility reaching a maximum of 36 %. By means multiscale structural chemical analysis electron microscopy energy dispersive X-ray spectroscopy, we show that multimodal strengthening mechanisms can be activated...
The current work implements a correlative microscopy method utilizing electron back scatter diffraction, focused ion beam and digital image correlation to accurately determine spatially resolved stress profiles in the vicinity of grain/twin boundaries tensile deformation twin tips commercially pure titanium. Measured local gradients were good agreement with misorientation values. role dislocation-boundary interactions on buildup is elucidated. Stress across twin-parent interface compressive...
Twinning-mediated plasticity in hexagonal close-packed crystal structures offers great potential for achieving lean Mg-based alloys with high strength and extended ductility. Micropillars from a MgZn1 Ca0.3 (ZX10, wt%) alloy pure Mg, each comprising one or more pre-existing {101¯2}<1¯011> extension twin boundaries parent orientation its c-axis perpendicular to the loading direction, were subjected situ micropillar compression. By means of correlative characterization using transmission...
A magnesium alloy with lean additions of Zn (1 wt.%) and Ca (0.3 wt.%), ZX10, pure Mg were subjected to orientation-dependent micropillar indentation tests at ambient temperature. Single-crystalline micropillars two different orientations fabricated activate extension compression along the c-axis, respectively. For both loading conditions, ZX10 exhibits a strengthening increment by factor 2 2.5 compared plasticity enhancement. Correlative transmission electron back-scattered diffraction...
In the present study, effect of resistance spot welding scheme (i.e. single and double pulse welding) on mechanical behaviour spot-welded DP1000-GI steel is investigated. It shown that at low current decreases maximum cross-tension strength energy absorption capability welds. The factors lead to lower performance welds are scrutinised. Local residual stress mapping reveals compressive perpendicular plane pre-crack either or fully released weld edge Orientation imaging microscopy analyses...
Fe–Cr is a model alloy for ferritic steels used in thermal power generation systems and envisaged as primary structural material future fusion reactors. However, upon heating and, further, under irradiation, suffers from phase decomposition leading to the formation of Fe-rich Cr-rich regions that induce simultaneous hardening embrittlement. In this study, we examine origins degradation mechanical properties by performing room-temperature situ micropillar compression tests on...
Rolled and annealed Mg-1wt. %Zn-1wt. %Gd-0.6wt. %Zr (ZEK110) alloys were subjected to room temperature in-plane compression along the rolling direction, followed by isochronal annealing treatments for 1 h. Despite a starting orientation favoring c-axis extension, as-deformed microstructure revealed hierarchical network of twins with profuse quantities second third generation twinning appearing within primary tension twins. Complex twin-twin twin–particle interactions accompanied activation...
