A material strength depends on its microstructure, which in turn, is controlled by an
engineering process. Strengthening mechanisms like work hardening, precipitate, and grain …

There are abundant studies on deformation mechanisms in metallic materials dominated by
grain boundaries and twin boundaries. In comparison, the influence of stacking faults on …

Mechanical robustness, electrical and chemical reliabilities of devices against large
deformations such as bending and stretching have become the key metrics for rapidly …

Nanotwinned metals are attractive in many applications because they simultaneously
demonstrate high strength and high ductility, characteristics that are usually thought to be …

This paper reports the quantitative measurement of a full spectrum of mechanical properties
of fivefold twinned silver (Ag) nanowires (NWs), including Young's modulus, yield strength …

Solidification cells and a high density of dislocations are two common features of additively
manufactured (AM) alloys that are processed using techniques such as laser powder bed …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

We show that slowly sheared metallic nanocrystals deform via discrete strain bursts (slips),
whose size distributions follow power laws with stress-dependent cutoffs. We show for the …

Linear defects in crystalline materials, known as dislocations, are central to the
understanding of plastic deformation and mechanical strength, as well as control of …

To ascertain the role of the solidification cell structures on the mechanical performance of Al-
Si-(Mg) alloys processed using the laser powder bed fusion (LPBF) technique, micropillar …
