Hello,
I'm a bit confused here about this topic. I can't seem to find a proper book on it so reading loads of papers of try and get a grip on it. I had come to the understanding that the high tensile and yeild strength developed here was due to the subgrain/micrograin size and the partial dislocations that they emitted.
But I read this paper that says that the high strength doesn't always come with the decrease in grain size and that the increase in strength is due to dispersion hardening. And another that explains that the good ductility experienced is due to annealing during the process and that this doesn't affect the strength.
Could someone set me straight please. Does this process just apply to nanocrystalline structures or to SPD in general?
Thanks
