The rapid progress in the development of multicomponent high-entropy alloys (HEAs) has inspired expansion of the high-entropy materials (HEMs) space to related materials such as high-entropy metallic glasses (HEMGs) and high-entropy ceramics (HECs). These different classes of materials together are popularly referred to as high-entropy materials (HEMs). This expansion has also prompted the re-emergence of several conventional materials’ synthesis routes, owing to the different versatilities associated with them. In this domain, mechanical alloying (MA) is acknowledged as a revolutionary technology for synthesizing multicomponent metastable materials, namely multicomponent supersaturated solid solutions, HEAs, quasicrystalline phases, intermediate phases, and amorphous alloys, with broad application potential. MA is a solid-state powder processing route that includes repeated cold welding, fracturing, and rewelding of powder particles. This permits the material to be processed considerably farther from equilibrium, thus, offering enormous possibilities for generating non-equilibrium phases and microstructures in HEMs. Further, the milled powders are consolidated into bulk form using spark plasma sintering, vacuum hot pressing, hot isostatic pressing, conventional sintering, and microwave sintering for property assessments. Nonetheless, MA involves multiple processing parameters to maximize the fabrication throughput of diverse HEMs. Optimal utilization of these parameters allowed production of a variety of engineered microstructures in HEMs during the last 15 years and competing with traditional alloys. In this context, a detailed overview of the MA process and a critical assessment of the field from the HEM standpoint is much needed. The proposed review will deliberate on the versatility of MA in developing different classes of HEMs having desired characteristics. In addition, this includes an in-depth examination of the various HEMs (HEAs, HEMGs, and HECs) synthesi

We investigated the electromagnetic quadrupole transition of baryon decuplet ( $$J^P= \frac{3}{2}^+$$ ) to octet ( $$J^P= \frac{1}{2}^+$$ ) using the statistical framework together with the principle of detailed balance. The statistical approach assumed the expansion of hadrons in terms of various quark–gluon Fock states. By specifying the appropriate multiplicity in spin, color and flavor space, the relative probabilities of strange and non-strange quark–gluon Fock state are calculated. These probabilities further accumulated in the form of statistical parameters, highlighting the importance of sea quarks and gluons in the electromagnetic transition. Our calculations includes the individual contribution of valence and sea (scalar, vector and tensor ) to the transition moment of baryons. The effect of flavor SU(3) symmetry and its breaking in both valence and sea quarks is studied by incorporating the strange quark mass. The strangeness in the sea is constrained by a suppression factor $$(1-C_l)^{n-1}$$ , which depends upon the free energy of gluons. The computed results get affected upto 60 $$\%$$ and exhibit the dominance of octet sea. The present work has been compared with updated experimental data and various theoretical predictions. The results obtained may offer important insights for future experimental studies.
