Why nitrogen gas is good in the annealing process of a

Nitrogen is good choice for annealing process,however unregulated flow of nitrogen can leads to nitride formation and can lowers the ductility of the materials.Gases sch as Argon can be another Whats the difference,and possible come out,of annealing Furthermore,after annealing in vacuum,it is possible to cool with overpressure nitrogen or argon so that a faster cooling compared to the annealing under Argon can be realised.Cite 2 What is Annealing Process and Why it is done? - Mechanical Aug 28,2018 Nitrogen Annealing#0183;Most of the time,annealing is carried out in the presence of endothermic gases.Endothermic gases are the mixture of hydrogen,nitrogen and carbon monoxide.Sometimes annealing is carried out in the presence of the forming gas.A forming gas is nothing but the mixture of hydrogen and nitrogen.Annealing is done inside the massive ovens.
