The cast ingots prepared using sand mould and metal mould were analyzed to investigate the effect of cooling rates on morphologies and characters of M2C eutectic carbides in M2 high speed steel.
The effect of Nb on the as-cast microstructures and the prespheroidization at elevated temperature of eutectic carbides of M2 high speed steel was studied.
