Is the Normal of the Slip Plane the Same as the Slip Direction?

The discussion revolves around confusion regarding the angles involved in slip planes and slip directions in materials science. Participants clarify that the angle between the normal of the slip plane and the axis of the rod is indeed related to the angle between the slip direction and the axis of the rod. It is emphasized that the slip direction is normal to the slip plane, which helps reconcile the apparent contradictions in the teacher's notes. The two relationships mentioned are equivalent, but they do not imply that the slip direction and the normal of the slip plane are the same. Overall, understanding these relationships is crucial for grasping the concepts of slip in materials.

Can someone tell me what you get from that law, getting confused by my teacher notes; they tend to contradict themselves somehow.
 
Engineering news on Phys.org
He said, that one of the angel of that this formula, is the angel between the normal of the slip plane and the axis of the rode, later he said that the same angel is the angel between slip direction and the axis of the rod, but this contradict itself seen we have got task’s were the slip direction isn’t in the slip plane.
 
The slip direction is normal to the slip plane. So the two relations that you mentioned are equivalent. It is not saying that the slip direction is the same. You said the normal of the slip plane and the slip direction: these are the same.
 
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...
