The purpose of the thesis was to develop a novel laser metal deposition process by combining
both wire and powder deposition techniques. The process was developed in order to locally
modify the properties of microstructure of H11 hot-work tool steel  i.e.  hardness and grain
size refinement. The modified material was later deposited on the surface of H11 hot forging
dies to improve local properties to mitigate the local dominant failure mechanisms  i.e.  wear
and heat checking.
