Click For Summary
A Frank-Read source generates dislocations by utilizing shear stress to create a dislocation loop. The center of the pinned dislocation moves in the direction of the applied shear stress, which is also aligned with the Burgers vector. This process involves the movement of dislocations that leads to the formation of new dislocation loops. Understanding the relationship between shear stress and the Burgers vector is crucial for grasping how dislocations are generated. Clarifying these concepts can help demystify the mechanics behind Frank-Read sources.

Hey sorry but I've been looking through several online resources and books but I cannot find a dumbed down explanation of how a frank reed source generates dislocations. Like what is the shears doing and the burgers vector?? I am so confused can someone enlighten me please? thanks

Does http://books.google.com/books?id=wh...ge&q="frank read source" dislocation&f=false" help answer your questions? The center of the pinned dislocation (later to become a dislocation loop) moves in the direction of the shear stress. The Burgers vector points in the direction of the shear stress also (for the entire dislocation).

Thread 'Need to anneal 5052 aluminum'

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
