WELCOME TO MOSTAFA HASSANI'S RESEARCH GROUP WEBPAGE

In-situ observations of high-velocity impact rebound (top) and bonding (bottom) for Al particle/substrate at micron-scale with nanosecond-level temporal resolution

Gradient plastic strain and extreme grain refinement down to nanoscale generated by severe shot peening of steel.

Micron-scale impact (~1000 m/s) causing melting in a ductile metal (left) and fracture in a brittle one (right).

Fatigue fracture in a not surface-treated (left), surface-hardened (middle), and surface-coated (right) alloy.

About Us

The EM3 Lab uses experiments, analytical theory, and computer simulations to understand the structure-property relation in structural materials, with particular emphasis on the extreme conditions of plastic strain, deformation rate, pressure, temperature, energetic particle/photon fluxes, etc. The EM3 Lab also exploits such extreme conditions for advanced processing and solid-state additive manufacturing.

EM3 Lab in the spotlight

In his interview with MIT News office, Mostafa explains what happens when tiny particles traveling at high speeds impact materials. High speed particles can bounce away, stick, or knock material off the surface and weaken it. New fundings can help us design erosion-resistant materials and develop more efficient coating and cutting processes.

Opening

There are currently several openings for MSc and PhD students with interests in mechanical behavior of materials, structural materials, and additive manufacturing. Postdoctoral Fellows, Visiting Researchers and Professors with relevant research interests and their own funding are always welcome to spend time in the EM3 Lab at Cornell.
