    Default Path dependence vs. independence

    Does the path one takes matter or is it immaterial. Boy, that's one that everyone in the material science of metals grapples with. I haven't spent much time studying metals but I have studied polymers a good bit and I can tell you that the path that one takes to get from state A to state B seems to be the determining factor in the development of the final properties. From what I've read about metals, the situation is similar. About the only things that I know about that are path independent are Thermodynamic State Functions, in fact, path independence is a requirement for a function to be a TSF. In short, I wouldn't bet the farm that it doesn't matter how one gets from one point to another, in fact the great variability in the results obtained by one honer versus another is probably caused by this path dependence of getting from A to B. It is also probably at the root as why one technique and one set of stones works great with one razor and not with another
