Tensile and Low‐Cycle Fatigue Behavior of Laser Powder Bed Fused Inconel 718 at Room‐ and High Temperature
Abstract
<jats:p>This study investigates the room‐ and high‐temperature (650 °C) tensile and low‐cycle fatigue behavior of Inconel 718 produced by laser powder bed fusion (PBF‐LB/M) with a four‐step heat treatment and compares the results to the conventional wrought material. The microstructure after heat treatment is characterized on different length scales. Compared to the wrought variant, the elastic and yield properties are comparable at both test temperatures while tensile strength, ductility, and strain hardening capacity are lower. The fatigue life of the PBF‐LB/M variant at room temperature is slightly lower than that of the wrought material, while at 650 °C, it is vice versa. The cyclic stress response for both material variants is characterized by cyclic softening, which is more pronounced at the higher test temperature. High strain amplitudes (≥ 0.7 %) at room temperature and especially a high testing temperature result in the formation of multiple secondary cracks at the transitions of regions comprised of predominantly elongated grain morphology and of columns of stacked grains with ripple patterns in the PBF‐LB/M material. This observation and pronounced crack branching and deflection indicate that the cracks are controlled by sharp micromechanical gradients and local 〈001〉 crystallite clusters.</jats:p><jats:p>This article is protected by copyright.
