Introduction

laser additive manufacturing is a novel manufacturing technique of layer-by-layer forming according to geometric model, provides a decent option for materials processing. We mainly focus on new materials (including high entropy alloys, superalloys etc.) design and laser additive manufacturing process (including selective laser melting and laser direct energy deposition).
