Abstract

In an extruded powder metallurgy superalloy, carbide particles are precipitated at the previous article boundaries. The role of these particles in the recrystallization behaviour has been studied by electron microscopy and hardness measurements. It was found that these carbide particles act as nucleation sites for recrystallization and inhibit growth of new grains.
