About this episode

Sophia Chen interviews Bharat Gwalani and Mert Efe about their innovative single-step method for fabricating samarium cobalt magnets.

In this podcast episode, MRS Bulletin’s Sophia Chen interviews Bharat Gwalani from North Carolina State University and Mert Efe from Pacific Northwest National Laboratory about their single-step, energy-efficient method for making a samarium cobalt magnet. Using a process they call “friction stir consolidation,” the researchers apply heat and pressure simultaneously to fuse the two powders together. Their method results in low porosity to make a magnetically stronger, higher quality material ...
