An undeformed specimen of some alloy has an average grain diameter of 0.04 mm. You are asked to reduce its average grain diameter to 0.010 mm. Is it possible? If so, explain the procedure you would use to and the name the processes involved. If it is not possible then explain, why?.

Jimmy Guzman · Answer 1

It is possible

Explanation:

An alloy is made up by the combination/mixing of two or more metals elements for the purpose of making/producing a stronger metallic element which is often most resistant to corrosion.

An undeformed specimen of alloy can have its average grain diameter reduced from 0.04 mm to 0.01 mm through the process of annealing the Alloy. Annealing is the process of heating a metal or alloy elements at a specific temperature and then allowing it to cool off gradually. this process is used to alter the physical and sometimes the chemical properties of the metal. when the metal is annealed it makes it to become workable and once a alloy is workable its diameter can then be reduced through cold work.

cold work is the work carried out on a metal to either increase or decrease it physical properties (in this case the diameter) when the metal is under ambient temperature

Jaidyn Banks · Answer 2

Yes, it is possible

Explanation:

Yes, it is possible to reduce the average grain diameter of an undeformed alloy specimen from 0.040 mm to 0.010 mm. In order to do this, plastically deform the material at room temperature (i. e coldwork it), and then anneal at an elevated temperature in order to allow recrystallization and some grain growth to occur until the average grain diameter is 0.010 mm
