Question
Why Heat Treatment of casting is done?To improve micro-structureTo Reduce Grain boundary segregationNoneBoth A & B
Solution
Heat treatment of casting is done for several reasons, including improving the microstructure and reducing grain boundary segregation. The process helps to refine the grain structure, making it more uniform and reducing the presence of defects such as porosity and shrinkage. This leads to improved mechanical properties, such as increased strength and toughness. Additionally, heat treatment can help to relieve residual stresses in the casting, which can improve dimensional stability and reduce the risk of cracking or distortion. Overall, heat treatment plays a crucial role in enhancing the quality and performance of castings.
