Post 15 Response

1) Grain boundaries are what are considered the weaker points of a metal crystal structure. This is usually caused by some impurities in the metal from the process of formation or where some of the crystals did not form properly. In manufacturing these boundaries can be influenced on how the metal is processed in ways such as heating cooling and special practices.

2) This can be done by the FFC Cambridge process or molten salt electrolysis. Basically the element is cooled very slowly to promote single crystal structures.
