There is a dependence of grain size (20–11 nm) on milling conditions. The microstructure remained very stable even at temperatures up to 500 °C for 5 h which is a minimum of 76% of the melting temperature. The materials produced by these methods were in the form of powders with particle size ranging from 200 nm to 10 μm. The morphology of the particles varied with the largest being rough and irregular and the smallest being spherical. Preliminary resistivity measurements showed low resistivity, 8.8 μΩ cm, which is comparable to that previously reported for thin films with grain sizes thousands of times larger. Nanoindentation was also performed, yielding an elastic modulus of ∼110 GPa.}, number={3}, journal={Intermetallics}, publisher={Elsevier BV}, author={Darling, Kris A. and Guduru, R.K. and Reynolds, C.

It becomes quite difficult to use conventional testing methods when the material availability is limited. In such instances, miniaturized specimen testing procedures such as shear punch test (SPT) becomes significantly useful for studying the mechanical behavior of materials. Current research deals with a novel SRT method employed on nanocrystalline Cu using SPT to study the deformation mechanism.}, number={10}, journal={Advanced Engineering Materials}, publisher={Wiley}, author={Guduru, R. K. and Wong, P. Z. and Darling, K. A. and Koch, C. C. and Murty, K. L. and Scattergood, R. O.}, year={2007}, month={Oct}, pages={855–859} }

The influence of number of ECAE passes on MgB2 PITs was also analyzed in terms of microstructure, density and mechanical properties. MgB2 PITs with iron tube were processed up to six ECAE passes. X-ray analysis of the compacts showed no other phases, other than MgO, in MgB2 compacts even after large mechanical working and annealing. Simple shear stresses predominant in ECAE constantly rendered compaction of the hard brittle MgB2 powders.}, number={1-2}, journal={PHYSICA C-SUPERCONDUCTIVITY AND ITS APPLICATIONS}, author={Nagasekhar, A.

In order to rationalize the testing methodology it is necessary to understand the effect of different testing procedure parameters such as specimen thickness and die-punch clearance on the evaluated mechanical properties. We present our understanding of the above parameters on the SPT yield strength using finite element modeling studies in conjunction with our previous experimental results.}, number={3}, journal={ADVANCED ENGINEERING MATERIALS}, author={Guduru, Ramesh K. and Nagasekhar, Anumalasetty V. and Scattergood, Ronald O. and Koch, Carl C. and Murty, Korukonda L.}, year={2007}, month={Mar}, pages={157–160} }
