The Hastelloy X superalloy is a widely used solid-solution Ni-based sheet alloy for gas turbines, aero-engine combustion chambers, and other hot-end components. To investigate the effect of microstructure, especially grain size, on its weldability, bars are homogenized, cold-rolled to thin sheets, recrystallized under different conditions obtain equiaxed microstructures with average sizes ~5 ?m...

Abstract Bicomponent regenerated cellulose fibres (bRCF) have been created in a core–shell configuration from waste textiles. Textile dyeing and colouration is known to be major contributor the environmental impact of producing textiles this needs addressed for become more sustainable. Coloration bRCF here was achieved by utilizing coloured textile shell component whilst using white cotton core...

Johnsen, Roksvold and Verdure have shown how fundamental invariants concepts of linear coding theory, such as weight enumerators higher weights, can be studied in the context matroid theory. They that Betti numbers, a its elongations, associated to code, determine both enumerator weights matroid. In same vein, Britz, Mayhew Shiromoto, introduced demimatroids natural generalization matroids. are...

Failure modes in recent earthquakes on lightly reinforced shear walls includes rebar fracture and out of plane buckling of its boundary elements. In latest edition of ACI 318 and also latest amendment of NZS 3101-2006 to avoid rebar fracture in boundary elements, the minimum reinforcement ratio for shear walls is increased. This experimental study investigates that rather than increasing reinfo...

The Spot welding is widely used for joining thin sheets in different industries; such as automotive industry. This method of welding is very easy to automate and maintain. In this study, the effect of nugget diameter on the tensile-shear strength of the spot welding joints was investigated. The specimens were manufactured from AISI 1008 HR sheets with 1.0 mm thickness. The eight different elect...

The influence of dyeing and spinning on the characteristics of cotton fibers and its impact on the properties of cotton mélange yarn has been investigated. Grey cotton fibers with mean fiber length and fineness of 29 mm and 4.2 micronair were pre-treated and dyed. Three ring yarns were spun from 100 % grey cotton (R.R.Y), 50-50 % blend of dyed and grey cotton (M.R.Y) and 100 % dyed cotton fiber...

The static properties, i.e., existence and stability, as well the quench-induced dynamics of vortex-bright type excitations in two-dimensional harmonically confined spin-1 Bose-Einstein condensates are investigated. Linearly stable vortex-bright-vortex bright-vortex-bright solutions arise both antiferromagnetic ferromagnetic spinor gases upon quadratic Zeeman energy shift variations. Their defo...

Investigations of the plastic deformation mechanisms Ni-W-based heavy alloys varying with increasing temperatures are very important for development hot forming processes and applications at elevated temperatures. In this study, continuous variation strength plasticity a novel alloy was investigated. The tensile Ni48W35Co17 sample 600 °C 471 MPa, which 47% lower than that 100 °C. A in an abnorm...
