The optimal conditions for thermal treatments. a Results of simple bending tests after comprehensive thermal treatments were carried out (: the samples break without being able to withstand one bend, : the annealed samples can withstand one bend without breaking, : the annealed samples can withstand two bends without breaking). b Temperature–time map (T-t) summarized through the results of the simple bending tests
