Abstract

Despite the potential and promising future of additive manufacturing (AM), the quality and performance of the products from metal additive manufacturing has been susceptible to skepticism. Herein, a nanoindentation method was implemented to compare the hardness, Young's modulus, and fracture toughness in AM and hot-rolled Inconel 718. Results indicated that Young's modulus and hardness of AM IN718 were nearly 25% and 50% smaller, respectively, compared to hot-rolled specimens. Indentation fracture toughness measurements showed that the traditionally fabricated specimens had a fracture toughness close to the reported range, but that of the AM samples was almost 25% smaller.
