Microstructural Evolution in Pure Aluminum in the Early Stages of Processing by High-Pressure Torsion
Measurements were taken to evaluate the evolution of homogeneity in disks of high-purity aluminum in the early stages of processing by high-pressure torsion. The results demonstrate that samples processed through 1/4 or more whole revolutions exhibit microhardness values which are generally higher in the centers of the disks than at the edges whereas after 1/8 turn the hardness is higher at the...
متن کاملHigh pressure synthesis of a hexagonal close-packed phase of the high-entropy alloy CrMnFeCoNi
High-entropy alloys, near-equiatomic solid solutions of five or more elements, represent a new strategy for the design of materials with properties superior to those of conventional alloys. However, their phase space remains constrained, with transition metal high-entropy alloys exhibiting only face- or body-centered cubic structures. Here, we report the high-pressure synthesis of a hexagonal c...
متن کاملMicrostructures and Mechanical Properties of Pure V and Mo Processed by High-Pressure Torsion
Two body centered cubic (bcc) metals, V and Mo, were processed by high pressure torsion (HPT) at ambient temperature. Hardness variation as well as microstructural evolution was examined with strain under a pressure of 2 to 6GPa. It was shown that the hardness increases with straining and saturates to a constant level with the grain size of 330–400 nm in V irrespective of the applied pressures....
متن کاملLocal Stress States and Microstructural Damage Response Associated with Deformation Twins in Hexagonal Close Packed Metals
The current work implements a correlative microscopy method utilizing electron back scatter diffraction, focused ion beam and digital image correlation to accurately determine spatially resolved stress profiles in the vicinity of grain/twin boundaries and tensile deformation twin tips in commercially pure titanium. Measured local stress gradients were in good agreement with local misorientation...
متن کاملThe Strength of Binary Junctions in Hexagonal Close-Packed Crystals
A comparative study of non-coplanar binary dislocation junctions in magnesium (Mg) and beryllium (Be) is presented to examine the effects of elastic properties and active Burgers vectors on junction formation and destruction in hexagonal close-packed (hcp) crystals via discrete dislocation dynamics simulations. Two junction configurations formed at intersecting prismatic ð01 10Þ=basal ð0001Þ pl...
