The strengthening mechanisms and precipitation behavior in AA2024 alloys with different Cu/Mg ratios (3.18 2.48) levels of plastic deformation (5 15%) were studied by X-ray diffraction, transmission electron microscopy Vickers microhardness measurements. Results demonstrate that hardening depends significantly on the interaction such as solid-solution, strain precipitation. Hardness is mostly influenced precipitation, which turn modified ratio. Modification Cu Mg content well affect Al2CuMg...

<title>Abstract</title> Background The percentage of older adults in Mexico has considerably increased owing to the declining birth rate and increasing life expectancy. leading cause death people aged &gt; 60 years is deprivation-related conditions, including pneumonia, energy-protein malnutrition, anemia, with an prevalence chronic noncommunicable diseases, mental illnesses, abuse. This study aimed comprehensively analyze association between quality (QoL) food insecurity among who reside...

This work shows a CoCrFeMnNi0.8V high entropy alloy (HEA) with multiple length-scale hierarchical microstructure, obtained upon cooling at ∼62.5 K/s, consisting of dominant globular sigma phase, FCC matrix and V-rich particles. The novel never reported before for the CoCrFeMnNiV system, results in about fourfold sixfold increase hardness wear resistance, respectively, compared to that CoCrFeMnNi alloy.

The effect of Ni 1-2 wt.% addition on the microstructure and hardness aged A319 alloy were studied. Characterization analyses by x-ray diffraction, optical microscopy scanning electron suggest clearly that forms Al-Ni-Cu-Fe, Al-Cu-Ni Al-Ni intermetallic compounds correlates well with equilibria conditions. Analyses transmission show aging heat treatment promotes microstructural changes in morphology, size, spatial distribution precipitates. Vickers micro-hardness test 1 2 specimens have a...
