- Abstract
- The inner architecture of material plays a seminal role in its overall properties. Micron size commercial purity aluminium particles are deformed into an assembly of “interlocked splats” at room temperature under a combination of high pressure and shear. This results in fabrication of highly dense, strong and ductile samples. Dissections of the sample at different radii and planes are examined to construct a “lookout map” featuring splat shaped deformed particles to study the induced inner architecture. The structure comprises of splats of large “radial to axial aspect ratio”, spread in parallel planes normal to the cylinder’s axis. Micro shear punch (MSP) tests are carried out to characterize the heterogeneous strength properties and the radial distribution of material’s density. A dimensional formulation is developed to interpret the MSP test data, taking into account some key parameters of the structure. The consolidated samples show an excellent shear strength; stronger than its solid counterpart and a pattern of radial strength distribution which is different with that of a similar solid sample.
