The direct band gap (<i>E</i><sub>g</sub>) CdTe crystals have been in limelight in photovoltaic application (PV) since the optoelectronic properties such as <i>E</i><sub>g</sub> (1.49 eV), absorption coefficient (~10<sup>5</sup> cm<sup>–1</sup>), <i>p</i>-type conductivity, carrier concentration (6 × 10<sup>16</sup> cm<sup>–3</sup>) and mobility (1040 cm<sup>2</sup>/(V s)) at the room temperature are reported that optimum for solar cells. Additionally, Cd-based compounds such as CdTe and CdZnTe have also been widely studied in the field of α and γ-ray radiation detector, because of their extraordinary advantages like large atomic number, low weight, high mechanical hardness, flexibility, and the availability of the constituent materials. CdTe has demerits like toxicity and high melting temperature, which will complicate the growth of stoichiometric cadmium telluride crystals at high temperatures. In this regard, the review work focused the periodic evolution of the growth protocols until now. The different synthesis methods, characterization, and recent progress in the field of crystalline CdTe were discussed briefly.

To address this, the ferrite phase has been identified as a suitable matrix for cast iron deformation due to its ability to provide satisfactory ductility and avoid brittle limitations. In this study, machined parts of ductile cast iron were subjected to an annealing process at approximately 900°C for 1 h before undergoing hot plastic deformation with varying degrees of reduction. The deformation was carried out using a cylinder-covered hot compression (CCC or CCHC) technique. The primary objective of this study is to gain a microscopic understanding of hot plastically deformed ductile cast iron and propose a mathematically formulated flow strain that takes into account the contributions of the microstructure’s constituent phases. This analysis aims to provide a comprehensive characterization of deformed graphite within the microstructure. Optical microscopy (OM) and scanning electron microscopy (SEM) were employed to obtain results for the characterization. The findings revealed that as the reduction increased, spheroidal graphite tended to transform into a lamellar structure, resulting in diverse properties.
