Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue in honor of Professor Manoj Gupta for his 60th birthday.

Dr Manoj Gupta received his PhD degree from the University of California, Irvine, USA, in 1992 and is currently an Associate Professor with the Department of Mechanical Engineering at the National University of Singapore. In August 2017, he was highlighted among the Top 1% Scientist of the World Position by The Universal Scientific Education and Research Network and among the top 2.5% by ResearchGate and Top 1% in the Stanford list of researchers. To his credit are (i) the disintegrated melt deposition technique and (ii) hybrid microwave sintering technique, an energy-efficient solid-state processing method to synthesize alloys/micro/nanocomposites. He has published over 600 peer-reviewed journal papers and owns two US patents. His current h‐index is 72, RG index 48, and his citation number is greater than 19,000. He has also co-authored eight books, published by John Wiley, Springer, and MRF-USA. He is Editor-in-chief/Editor of twelve international peer-reviewed journals. A multiple-award winner, he actively collaborates with researchers in/visits Japan, France, Saudi Arabia, Qatar, China, the USA, and India.

In honor and recognition of Professor Gupta’s outstanding career contributions to the field of light metals, metal matrix composites, and innovations in materials processing, we would like to invite you to submit an article for the Special Issue to be published in Technologies. Research articles or review papers relating to metal-based materials, metal matrix composites, and innovation in materials processing are welcome for publication in this Special Issue.

In this paper, the self-curing process was considered and found to be a better alternative to the conventional curing process for concrete structures in Ethiopia. It is well known that water plays a significant role in the curing process of preparing concrete in the construction industry. A good quality water is required for the conventional curing process, but that is scarce in Ethiopia. Curing concrete for bridges and roads is difficult in Ethiopia due to the poor quality and scarcity of water. In this study, Polyethylene Glycol (PEG) 600, a self-curing process, is considered as an alternative. Using the M40 Grade mix, four different percentages of PEG-600, 0.0, 0.5, 1.0, and 1.5 of cement weight, were studied, and the specimens were tested. Here, M40 grade stands for “a concrete mix with a characteristic compressive strength of 40 N/mm2, i.e., 40 Newton per square millimeter”. Additionally, the mechanical strengths and properties of both conventional and self-cured processed concretes were calculated and compared. The present investigation concludes that PEG 600 offers significant results for self-curing concrete. The study procedure, results, and recommendations are presented in the text of the paper.

The work is devoted to the study of technology that can be used to obtain lithium-containing ceramics of the Li2+4xZr4−xO3 type using the method of solid-phase synthesis combined with thermal annealing at a temperature of 1500 °C. A distinctive feature of this work is the preparation of pure Li2ZrO3 ceramics with a high structural ordering degree (more than 88%) and density (95–97% of the theoretical density). During the study, it was found that a change in the content of initial components for synthesis does not lead to the formation of new phase inclusions; however, an increase in the LiClO4·3H2O and ZrO2 components leads to changes in the size of crystallites and dislocation density, which lead to the strengthening of ceramics to external mechanical influences. The results of the measurements of thermophysical characteristics made it possible to establish that the compaction of ceramics and a decrease in porosity lead to an increase in the thermal conductivity coefficient of 3–7%.

Growing concerns like depleting mineral resources, increased materials wastage, and structural light-weighting requirements due to emission control regulations drive the development of sustainable metal matrix composites. Al and Mg based alloys with relatively lower melting temperatures qualify for recycling applications and hence are considered as the matrix material for developing sustainable composites. The recent trend also explores various industrial by-products and agricultural wastes as green reinforcements, and this article presents insights on the properties of Al and Mg based sustainable metal matrix composites with special emphasis on green reinforcements and processing methods.

In recent times, an alternative synthesis pathway involving severe plastic deformation for Mg-based materials has been explored involving the generation of turnings according to a set of machining parameters and cold compaction into billets followed by hot extrusion. This is known as the turning induced deformation (TID) method and has shown potential to alter the properties of resulting Mg-based materials for the better, not to mention economic benefits arising from this processing method. This work summarizes exploratory efforts involving this method for synthesis of Mg-based materials. The TID method resulted in overall superior properties compared to conventional processing methods, while two distinct parameters (high depth of cut and low cutting speed) were found to have significant positive influence on the final material properties, and as such are considered to be suitable basis on which further exploratory work in this field may be conducted.
