Abstract The recovery and separation of metals from aqueous solutions is one the research hotspots in hydrometallurgy, environment protection, analytical chemistry, etc. Much attention has been paid to solvent‐impregnated resins (SIRs) since these were firstly proposed for extraction metals. SIRs are characterized by high efficiency selectivity, convenient preparation, easy operation because they combine unique advantages solvent ion exchange. preparation features summarized their...
The effects of partitioning temperature and time on the strengthening plasticising mechanism a one-step quenching (Q&P) steel were investigated. results show that as decreased, lath martensite became finer with higher dislocation density, while density RA amount decreased increasing time. Lower shorter are conducive to achieve high ultimate tensile strength 1377 MPa better total elongation 12.3% for low-carbon Q&P steels. Meanwhile, caused by solid solution main mechanisms In addition, new...
A series of poly(acrylic acid) (PAA)–poly(vinyl alcoho) (PVA) semiinterpenetrating (SIPN) and interpenetrating (IPN) polymer network membranes were prepared by crosslinking PVA alone or both PAA. Glutaraldeyde ethylene glycol used as agents for the PAA networks, respectively. The presence increases permeability while improves their mechanical film-forming properties. properties investigated via tensile testing. These hydrophilic are permselective to water from ethanol–water mixture ethanol...
Increasing disruption in the rare earth supply chain creates an urgency to develop alternative resources, which utilization of coal-based materials presents great potential. Nevertheless, environmental control is a significant challenge extraction processes. This study was conducted contribute limited information on removing thorium and uranium from earths while products are used as feedstock. The laboratory studies suggested that selective precipitation solvent approach yields most...
As an indispensable actuator, the hydraulic cylinder has widespread industrial applications in mechanical engineering. The cushion characteristics of directly affect its performance and reliability, especially one utilized system with fast response, high flow rate, instantaneous super power. In order to analyze characteristics, three different simulation models are established. Furthermore, experiments concerning pressure accomplished verify validation models. It was found that integrated...
This study investigates the effect of aluminum (Al) on microstructure, micro-hardness, and wettability environmentally friendly Sn-20Bi-xAl (x = 0, 0.1, 0.3, 0.5 (wt.%)) solder alloys. Scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) analysis, X-ray diffraction (XRD), were used to identify microstructure morphology composition. The spreading area contact angle alloys Cu substrates measure results indicate that Al increased hardness a maximum value ~27.1 HV for x...
Abstract In this study, we investigated the effects of quenching and tempering temperatures on microstructure mechanical properties low-alloy wear-resistant steel NM450. The were 870 °C–1200 °C, held for 36 min. After with 910 200 °C–600 °C 60 results showed that as temperature increasing, original austenite grain size increased proportion high-angle boundaries gradually decreased, which was detrimental to toughness steel. inter-lamellar-retained remaining in martensite lath during satisfied...
During low‐temperature tempering of wear‐resistant steel, ε‐carbide precipitation can effectively relax residual stress, and its microscopic mechanism is currently unclear. To reveal the stress relaxation during precipitation, density functional theory calculations are combined with experiments to explore growth behavior evolution. The results show that includes two stages: ε‐precursor formation nucleation, in situ nucleated from matrix. precipitation‐induced mainly occurs early stage...
Samples gotten from lubricating oil used in the marine diesel engine cylinder piston ring were analyzed with spectrum analyzer to get value of wearing elements. The time series autoregressive (AR) prediction model was established monitoring data predict data. Actual results showed that, AR can handle non-linear dynamic data, reflect nonlinear relationship among various elements, and accuracy high a strong practicability.
