Along with slurry concentration and particle density, particle size distribution (PSD) of tailings also exerts a significant influence on the yield stress of cemented paste, a non-Newtonian fluid. In this work, a paste stability coefficient (PSC) was proposed to characterize paste gradation and better reveal its connection to yield stress. This coe...

After reporting on the ability of micro-EDM to significantly alter the transformation behaviour of Nitinol whereby increasing discharge energy reduces thermal hysteresis and results in a three-peak reverse phasetransformation on heating, this study helps to further characterize the Nitinol micro-EDM process. This is by closely varying discharge ene...

The effects of agar, alginate, butter, olive oil, and carrots on the mechanical and rheological properties of potato puree prepared by two different cooking methods (microwave heating (MP) and boiling (BP)) were investigated and interpreted in terms of starch microstructural changes. Microscopic observations revealed more aggregated and densely con...

AbstractA review of the current state of research in the field of oil rheology is presented as the basis for quantitative characterization of oil flow in the pipeline system. Based on recent publications, a picture is presented of the dependence of the rheological properties of oils of various types on their composition. The features of the flow of...

The viscoplasticity and compressive strength of cement with high erosion performance were studied. The influences of curing temperature and content of ground granulated blast furnace slag (GGBFS) on these performances of the medium heat cement (including high iron and low calcium phase) were also investigated. The results indicate that the medium h...

The results of the position analysis of the yield stress &tau / 0.3 on the "stress&ndash / strain" (&tau / &ndash / &gamma / ) dependences, received at the torsion of specimens of Ti49.8Ni50.2 (at%) alloy are presented. The critical stress &tau / 0.3 (IV), corresponding to the end of linear stage III and the beginning of the intensive development o...

The paper deals with the variability of mechanical properties of EPSTAL steel rods produced in Polish steelworks, i.e. yield stress Re, tensile strength Rm, and elongation Agt. Our study is based on fundamental engineering static room-temperature tensile tests for large series specimens which have been made by manufacturers as the part of a factory...

Relying on nanoindentation technology, we investigated the elastic-to-plastic transition via first pop-in event and estimated the corresponding shear stress for incipient plasticity, i.e., yielding in the three typical orientations, i.e., X-112° / , Y-36° / , and Y-42° / planes. The occurrence of incipient plasticity exhibited a stochastic...

Complex behavior of 33 commercial lotions was investigated in order to identify correlations between laboratory instrumental measurements and sensory attributes of these products. Sensory attributes were evaluated by trained panelists. Six attributes were identified as potentially related to rheology, which belong to three main sensory categories: ...

Abstract Mining activities worldwide are subject to serious geotechnical accidents involving tailings dams. Therefore, many studies have focused on tailings dewatering before their deposition. This article studies the rheological properties of flocculated and thickened nickel tailings in order to determine the effect of the initial solid concentrat...
