Question

An undeformed specimen of some alloy has an average grain diameter of 0.050 mm. You are asked to reduce its average grain diameter to 0.020 mm. Is this possible? If so, explain the procedures you wo

Answer 1

Answer:

Yes it is possible

Explanation:

Procedures to be taken:

Step 1:

I will deform the specimen, that is, I will subject the specimen to plastic deformation at room temperature.

Step 2:

Also, I will anneal the deformed specimen at a high temperature.

Step 3:

Then, recrystallize the annealed specimen

Step 4:

Finally, I will facilitate the grain growth until the average grain diameter becomes 0.02mm.
