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...
Abstract A medium Mn steel (MMS) was cast by employing a vacuum induction furnace. After that, the hot rolled (HR) in order to achieve final thickness of 1.4 mm. The microstructure sheet found be composed martensite and little amount austenite, Ultimate Tensile Strength (UTS this processing condition close 1600 MPa negligible elongation found. An intercritical annealing (IA) heat treatment applied promote austenite reversion increase its stability. Previous thermodynamic simulations...
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 recent discovery of new Pt-based minerals has opened up the opportunity to generate synthetic materials. Here, geologically inspired approaches designing and synthesizing novel platinum alloys, from ternary high-entropy alloys (HEAs), are showcased. Empirical mathematical models thermodynamic parameters were used predict formation solid solutions with single-phase structures in (Pt3-xPdx)(Cu2-yNiySn) system. Five compounds, having ordered L10-type structures, have been obtained at...
In this study, the CrCuFeNiTiAl1 equiatomic alloy was used as a base, which modified by adding graphite in proportions of 0.5, 1.0, 2.5, and 5.0 mol%. The samples were obtained powder metallurgy sintering at 1,200°C for 2 h furnace with protective argon atmosphere. structural characterization performed XRD. Microstructural evaluation determined SEM. best mechanical microhardness compressive strength results lowest amount (238 mHV 1000 MPa, respectively). Density values showed that low...
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...
