Abstract null null Deformation and wear in a hot-forging die made of H21 steel was investigated using finite element analysis, nanoindentation, microhardness, optical scanning method, electron backscattering diffraction, and transmission electron microscopy. The results showed that deformation and wear were concentrated more in some die regions during the hot-forging process. In these regions, the processing parameters such as strain, strain rate, and temperature were suitable for the occurrence...

Abstract null null In the recent years, rapid developments in nanotechnology have developed a great prospects for researchers to check up. Thermal performance of nanofluid is well scrutinized by global scientists. Keeping aforesaid pragmatism of nanofluids, we have considered Sutterby liquid under thermophoretic and Brownian movement's aspects. Radiation and stratification phenomenon for thermal analysis of Sutterby nanoliquid are considered. By invoking some appropriate transformations and boun...

Abstract null null This study used hot-injection and ice-water bath methods to air-synthesize perovskite CsPbBr3 quantum dots (QDs-CsPbBr3) doped with aloe vera plant (AV-P). The addition of AV-P does not change the microscopic reorganization of QDs-CsPbBr3, and still maintain the cubic lattice structure. The pristine QDs-CsPbBr3 and AV-P:QDs-CsPbBr3 films, where narrow photoluminescence (PL) bandwidths of 24.88 and 22.65 nm as well as emission peaks at 524 and 521.6 nm, respectively, can be see...

Abstract null null We found that two types of Cu-doped Bi2Te3 thin films fabricated by dissimilar sputter process had different microstructures and non-stoichiometries (Bi:Te ratios). We investigated the different levels of Te-vacancy ( null null null null V null null T null e null null null 2 null + null null null null null ) concentration in the films affected the point defects and the thermoelectric property of the films. The Cu additives were substituted for the Bi-sites (form null null null...

Abstract null null This paper deals with the fabrication of porous materials using direct energy deposition, which is a versatile 3D printing technique for metals. To manufacture a porous material, a mixture consisting of AlSi12 powder and a foaming agent (ZrH2) is sprayed onto an aluminum substrate and subsequently fused with the substrate using a high-power laser beam. We examined the effects of the main process parameters, namely the laser power, scanning speed and foaming agent ratio, on the...

Abstract null null The continuous casting behavior of medium manganese steels (MMnS: 6Mn, 6Mn–1Si, 6Mn–1Si–1Al, 10Mn–1Si and 10Mn–1Si–1Al) have been investigated and compared with unalloyed carbon steel C30. A series of in-situ melting/re-solidification hot tensile tests were conducted in the temperature range 800–1450 °C. The corresponding tensile forces and ductility parameters were monitored. Differential thermal analysis (DTA) was applied to determine the liquidus temperatures. The solidifie...

Abstract null null The austenitic stainless-steel biomaterial, AISI 316L stainless steel, is one of the most widely used for orthopedic or prosthetic implant devices because it is easy to manufacture at a relatively low cost. However, corrosion is a challenging issue related to major alloying compounds with body fluids and wear. Therefore, this study aimed to develop a biomaterial of Fe–Al–Mn alloys by minimizing chromium (Cr) and nickel (Ni) contents. In the research, an attempt has been made t...

Abstract null null Chile is the world's leading copper producer (28.3%) and maintains approximately 23.0% of current global reserves. Chile is faced with a significant risk posed by its collection of the most unsustainable and antiquated smelter operations among major copper producers worldwide. Moreover, forecasts also indicate a trend toward higher proportions of copper sulphide ores that carry high impurities, especially arsenic. To achieve the planned production increases, improve competitiv...
