Hi ...

I have a question about a job in the material science courseWe give the hall petch type that denotes the dependence of the strength on the average grain diameter d, also has a value close to 1mpa. I have to show in a diagram σ-d ^ 1/2 the transition from type 2 crash to crank type 3 cogometry function for a space-centric cubic metal

In the future, homework must be posted in a homework forum, and you must fill out the template. Threads also need a more informative title than, "homework help"

Most important, the helpers aren't allowed to just give the answer. You must show your attempt at solution first, and then they'll give hints.

So please begin by showing us how you would try to solve the problem.
