Coble doctoral thesis at General Electric

Tom recounts that Coble was Ashby's student at Harvard who did his doctoral thesis at General Electric, invented Coble creep, and came back to MIT as a faculty member during Tom's student years. Nabarro identified as a South African metallurgist. Not a developed case — purely biographical anchor for the creep mechanisms.

He had a student when he was at Harvard do a doctoral thesis at General Electric — Coble, who graduated from MIT, went to General Electric research, invented Coble creep, and came back as a faculty member when I was a student. And Nabarro creep — Nabarro was a South African metallurgist who came up with an explanation of grain boundary creep. So Nabarro creep is grain boundary creep, Coble creep is a variation on Nabarro creep with a different type of diffusional mechanism. And dislocation creep is movement of dislocations within the crystal rather than at the grain boundary. So there are different ways to look at the dislocations.
