Conventional P91 and boron modified P91-steels were considered in the present investigation. Using Gleeble, weld intercritical heat-affected zone (ICHAZ) was processed. microscopy done along with electron back-scattered diffraction for both specimens. Lath boundary of martensite more, preferably oriented P91B-ICHAZ than P91-ICHAZ. Lattice strain high lath mobility low comparison to Large fraction ferritic grain structure (39.1%) small fresh martensitic (9.5%) P91-ICHAZ, whereas (10.7%) large...
Development of self-nanoemulsifying drug delivery systems (SNEDDS) docosahexaenoic acid (DHA) is reported with the aim to achieve enhanced dissolution rate. The optimized composition liquid SNEDDS (L-SNEDDS) formulation was Labrafil M1944 CS, 47% v/v Tween 80, 27% Transcutol P, and 0.1% DHA. L-SNEDDS were solidified using Syloid XDP 3150 as solid porous carrier. droplet size, polydispersity index, zeta potential, percentage loading, cloud point for found be 43.51 ± 1.36 nm, 0.186 0.053,...
Joining of dissimilar aluminum alloys are widely used in automobile, aerospace and shipbuilding industries. The defect-free joining using conventional technique is a challenging task for welding engineer. Friction stir has been established as one the most promising processes defects-free alloys. In this study, hybrid approach grey relational analysis with principal component analysis, applied multi-objective optimization process parameters friction AA5083/AA6063 Three responses namely...
Noncarious tooth surface loss is a normal physiological process occurring throughout the life, but it can often become problem affecting function, esthetics or cause pain.The purpose of this study was to assess effect erosive and abrasive challenges on microhardness wear enamel three different restorative materials, that is, nanofilled composite, microfilled composite resin-modified glass ionomer cement (RMGIC) by using Vickers tester profilometer respectively.Nanofilled (Filtek(™) Z350 ×...
The present research investigates the application of artificial intelligence tool for modelling and multi-objective optimization friction stir welding parameters dissimilar AA5083-O–AA6063-T6 aluminium alloys. experiments have been conducted according to a well-designed L 27 orthogonal array. experimental results obtained from were used developing neural network-based mathematical models tensile strength, microhardness grain size. A hybrid approach consisting network genetic algorithm has...
Super-cooled and amorphous lipid-based colloids are highly desirable delivery systems because of their ability to encapsulate compounds in a soluble or non-crystalline state. In this study, we demonstrate the preparation characterization super-cooled nanoscale colloidal dispersions containing high concentrations phytosterols (PSs). PSs hydrophobic natural bioactive that known significantly reduce blood cholesterol levels humans, but insoluble water poorly common lipids such as...
Engine performance and emission characteristics of unmodified biodiesel fueled diesel engines are highly influenced by their ignition combustion behavior. In this study, were studied when the engine operated using different blends (B10, B20, B30, B40) normal fuel (B0) as well varying compression ratio from 16.5 : 1 to 17.5 18.5 1. The change resulted in 27.1%, 27.29%, 26.38%, 28.48%, 34.68% increase cylinder pressure for B0, B10, B40, respectively, at 75% rated load conditions. Higher peak...
Modified 9Cr1Mo (P91) having ferritic/martensitic structure is a candidate material for thermal powerplant industry due to its enhanced creep resistance. Fusion welding of P91 steel nurtures heat affected zone (HAZ) which gives rise infamous type IV failure/cracking. The origination cracking still remains ambiguous mainly sampling constraints from - HAZ subzones owing thin width HAZ. In present work, this issue investigated with the help small punch impression technique. Thermo – mechanical...
