Today, we showed some admitted female students how awesome Pitt and materials science are. These students have been admitted to Pitt engineering but haven’t committed to a school yet, and also haven’t chosen their major yet. We showed them around the ANSYS Additive Manufacturing Lab, and demonstrated the amazing shape-changing properties of NiTi wire. The […]

“One technology uses magnetic fields to generate mechanical work. The other enhances the magnetic properties of 3D-printed materials. Combined, they could lead to efficient, economical production of magnetic actuators used in everything from sensors, robotics, and mechanical devices to power generation. An award from the National Science Foundation (NSF) has researchers at the University of Pittsburgh playing […]

Another bit of fun we’ve been having is casting metals. We vacuum and backfill to the right pressures: And we melt things! We place significant value on safety, and use all of the necessary personal protective equipment (PPE) to keep us safe!

It’s hard to find people who share a certain familiarity with and fondness for a specific crystalline phase of a material. But one phase that has almost a cult following is martensite! Martensite is characterized by a martensitic transformation – a transformation that is diffusionless. In most phase transformations, the atoms move around within the […]

One of the newer machines within our capabilities is the Transmission Electron Microscope (TEM). Yesterday, Erica and Amir examined some samples for a collaborator with the TEM. Transmission electron microscopy requires an electron-transparent sample, and is capable of resolving individual atoms. Among the information that can be gained from the TEM are atomic structure, dislocation […]
