“…Advances in electron microscopy and diffraction have led to new developments in the field of nanotechnology, and the technique is now used to study the atomic structure of nanoparticles and other nanostructures with unique properties. The equation for electron diffraction is based on Bragg's Law, which relates the wavelength of electrons to the angle at which they diffract from a crystal lattice [32]. nλ = 2d sin(θ)……………………………………………………………………………….…”

In nanomaterials and microstructural evolution, electron microscopy has had an important effect on materials investigation. Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), Electron Diffraction, Operando Electron Microscopy, and Aberration-Corrected Electron Microscopy offer the investigation on understanding of nanoscale material properties and structure. The present research covers the basics, advantages and disadvantages, and material-related applications of various electron microscopy techniques. TEM is useful for investigating atomic arrangements and imperfections in materials, while SEM offers micro- to nanoscale topographical, morphological, & compositional information. EDS, frequently employed with SEM or TEM, analyzes elements and compounds to determine material compositions. Opando Electron Microscopy allows researchers to observe and assess materials during catalytic reactions and battery charge/discharge cycles. This approach is vital for knowing how dynamic processes influence nanoscale material characteristics and behaviour. Another advanced technique, Aberration-Corrected Electron Microscopy, corrects lens aberrations that interfered with electron microscope resolution. This adjustment enables imaging at sample-limited resolutions, allowing further studies of atomic structures & flaws. These electron microscopy methods significantly improve nanomaterial microstructural evolution understanding. These have enabled extensive study of flaws, transitions between phases, and formation mechanisms, which are essential to producing optimal materials.

“…Fig. 1 Piezoelectric Material [28] Shape memory alloys are a class of intelligent materials that can undergo a reversible alteration in their shape or dimensions in response to variations in temperature or stress [29]. These materials possess the capability to be programmed to retain a particular shape or state, and subsequently revert to that state upon the application of an external stimulus.…”

“…11,12 It is worth noting that the choice of deformation temperatures has a significant effect on the microstructure and mechanical properties after the ECAP deformation. [13][14][15] The high deformation temperatures resulted in grain growth, and the friction between the sample and the ECAP mould led to the formation of cracks on the surface of the samples. However, the lower deformation temperatures restrict the activation of prismatic and pyramidal slips in the Mg-Sn-based alloys, making it challenging to deform them and even causing fracture.…”

Numerous studies of equal channel angular pressing (ECAP) considered the sample and mould temperatures as a whole, ignoring their different control effects during ECAP deformation. In this paper, the microstructure and mechanical properties of Mg-Sn-Zn-Zr (TZK) alloys were investigated after ECAP deformation at different mould and sample temperatures. The results revealed that higher mould temperatures controlled the actual deformation temperatures and lower sample temperatures prevented grain growth during preheating. After ECAP deformation at mould temperature of 300 °C and sample temperature of room temperature, the alloy consisted of abundant dynamical recrystallisation grains, with an elongation of 30% and a strength of 251.49 MPa. This study would provide a novel idea for the optimisation of the ECAP process.
