Abstract: An improved apparatus and method of fabricating long nanostructured or ultrafine grained tubes includes, in one implementation, expanding and extruding a sample material through cyclic deformations. The first cycle begins with expanding the sample through a die unit by applying pressure using a punch box, then with extruding the sample by applying back pressure using a stationary mandrel, which in turn reduces the expanded sample diameter to the original diameter. The next cycle begins with inverting the die unit to further extrude the sample with no need to apply back pressure. Furthermore, resistant forces against the sample are reduced by using a lubricant material inside the die unit, thus allowing continuation of additional cycles without constraining the sample length, resulting in desired strength and elongation.
