Abstract: The Rheo-diecast process has been rapidly developed and increasingly used in China in the recent 5 years. The high solid fraction (solid content close to 50%) rheo-diecast components were commercially used in the transportation markets mainly because of lightweight. The mechanical properties of the high solid fraction rheo-diecast components are obviously superior than that of the conventional liquid diecast parts. The defects such as oxide, gas entrapment, shrinkage porosities are well prevented in the high solid fraction rheo-diecast parts. The high solid fraction rheo-diecast parts can be fully T6 heat treated. A comparison between high solid fraction rheo-diecast part and conventional liquid diecast part will be described in detail. The low solid fraction (solid content 5-20%) rheo-diecast components were widely used in the 5G communication markets. The future perspectives of Rheo-diecast process will be described at last. 1. Cost reduction. 2. Production consistency. 3. New Rheo-diecast alloys development. 4. Numerical simulation of Rheological filling.

Abstract: The article presents a study of the physical and technical properties of ash and slag waste Coal Power Plant. The main problem when using ash-slag mixtures is the variability of the particle size distribution of the material. Determining the characteristics of slag stored in the dumps of thermal power plants will help to choose the separation methods of this material, to address the disposal and accumulation of industrial waste, to expand the scope of their application. The obtained research results of physical and technical properties of waste of the Coal TPP testify to wide potential in the further use in many branches of the industry. Possible applications include fillers for concrete, materials for sandblasting (abrasive material), raw materials for the metallurgical industry, additives for the manufacture of binders, etc.

Abstract: Since the discovery of superconductors, research has shifted from simple metals to alloys and further to complex compounds. As the record of critical temperature gradually increases, more opportunities and challenges have emerged. The Bardeen-Cooper-Schrieffer theory failed to explain certain observations of unconventional superconductors. However, breakthroughs have been made on the new understanding of unconventional superconductors. This article will introduce various challenges to and opportunities for the application of unconventional superconductors, including the high-temperature superconducting fault-current limiter and the superconducting energy-storage system.

Abstract: Reducing the melting point, in creasing the thermal stability limit, and enhancing the specific heat capacity of molten salt are the research hotspots in the field of medium and high temperature energy storage in recent years. From the perspectives of the melting point, thermal stability limit, and specific heat capacity of nitrates, we summarize the melting point, thermal stability limit, and specific heat capacity enhancement of molten salts with different compositions and ratios. The melting points of molten salt with different compositions and ratios are compared. Furthermore, the enhancing effect of various nanomaterials on molten salt is elucidated. The application of nitrate molten salt is also summarized to provide a reference for the research and application of novel molten salts. Keywords: Nitrate Molten Salt; Melting Point; Thermal Stability Limit; Specific Heat Capacity; Application

Abstract: Compared to conventional metal forming methods, processing by severe plastic deformation is mostly used to improve the mechanical properties and not for the shaping of a product. Processed material usually has an average crystal grain size of less than a micron and as a result, the material exhibits improvements in most of the mechanical properties, such as yield and ultimate tensile strength, microhardness, sufficiently high workability, good corrosion resistance, and implant biocompatibility and others. In this paper, a brief review of the processing by severe plastic deformation was presented, including the benefits, major methods, and the application. Additionally, a brief review of two methods made by authors was made.
