Why are the superalloys sometimes subjected to secondary
melting processes?
Answer / madiha
In order to get homogenized composition. Secondary melting process is usually vacuum arc remelting which involves the melting of electrode drop by drop and solidification occure layer by layer as a result homogeneous composition is obtained.
