The residual stress and surface roughness enhancement of ground surfaces can decrease the lifetime workpiece by reducing its fatigue life. It is critical to accurately predict minimize toughness in order enhance efficiency part production using grinding operations. A virtual machining system developed research work integrity during operations Inconel 718. cutting temperature calculated alloy Jo...

In this study, the effect of a high-speed AP 7.62 bullet on Ti6Al4V, AISI 4340, Inconel-718, AlSi10Mg and Al 6061 - T6 materials at different impact angles were investigated by using finite element package software LS-DYNA 971. 4340 was taken as material 850 m/s speed for ballistic investigation. Angle obliquity against plates has been in range 0-80º. Simulations carried out 5 degrees increment...

Investigation of the selective laser melting (SLM) process, using finite element method, to understand influences power and scanning speed on heat flow melt-pool dimensions is a challenging task. Most existing studies are focused study thin layer thickness comparative same materials under different manufacturing conditions. The present work analysis thermal cycles complex behavior high multi-la...

A suite of experimental tools and fast-acting, numerical-simulation techniques was used to quantify the precipitation behavior three nickel-base superalloys: IN-100, LSHR, 718. Experimental methods comprised differential scanning calorimetry (DSC) establish specific heat as a function temperature selected direct-resistance heating trials (using Gleeble® machine) obtain samples for microstructur...

Schismatoglottis mons Kartini is described as taxonomically novel species assigned to the Asperata Complex. a highland mesophytic found at c. 718 m a.s.l. most like lowland gillianiae P.C. Boyce and shaleicola P.C.Boyce & S.Y.Wong.

Materials and Methods: A total of 1,422 subjects, 704 women (49.5%) and 718 men (50.5%), were enrolled in the Maracaibo City Metabolic Syndrome Prevalence Study. The results were expressed as medians and inter-quartile ranges (p25-p75). Differences were determined through the Mann-Whitney U test and one-way ANOVA test with the Bonferroni adjustment. A multiple logistic regression model was desi...
