At the 45° forming angle, the material dislocation density is the highest, and the grains are most prone to the dislocation slip. The macroscopic properties show that the microhardness of the material is small. The "Three-stage" model reveals the micro-evolution mechanism of work-hardening ...

The density was calculated using the liquid immersion technique and is compared to the theoretical value. The results showed that hybrid composites offer a lower density compared to single reinforced composites. However the density of single reinforced composites was lower than that of un-reinforced ...
EBSDdislocation densityaluminumDuring and after plastic deformation of metals, dislocations tend to evolve into generally well-defined structures that may include tangles, bands, cell walls, and various additional features. Observation of these structures by electron backscatter diffraction is only ...
AA2050-T84 is a relatively new alloy, which has high strength and low density. One of the important problems encountered in the machining processes is the distortion of the workpiece. So, to reduce distortion ratio according to the selecting cutting parameters is exclusively crucial. Distortion ...
Also, the properties of the AA7050 composite, such as density, hardness, tensile strength, and wear behaviour, were studied. The properties of AA7050 composite, such as hardness, tensile strength, and wear resistance, increased up to 5 wt.% titanium dioxide addition, and beyond that, it ...
