Plasticity and fracture behavior of high-strength steels at low temperatures

High-strength steels with a body-centered cubic (bcc) crystal structure are generally expected to exhibit limited ductility at low temperatures due to the ductile-to-brittle transition. In this talk, we show that some high-strength bcc steels can nevertheless display unexpectedly large macroscopic ... [more]

Sintering Fundamentals of Nano-Metallic Particle Interconnects

Sintered copper (Cu) nanoparticles have emerged as a promising substitute for sintered silver (Ag) nanoparticles in power electronics packaging, offering comparable electrical and thermal conductivities, superior mechanical strength, and lower cost. However, the complex interactions between ... [more]

Ancient craft, new perspective: Recovery and recrystallization of deformed metal nanoparticles

Metallic nanoparticles are utilized in a growing number of applications due to their unique and tunable properties. However, one of the primary tools used to tune bulk metals properties, recrystallization, is yet to be used in the case of nanoparticles. We studied pristine, single crystal platinum ... [more]
