A damage evolution model based on micro-structural characteristics for an additive manufactured superalloy under monotonic and cyclic loading conditions
Source abstract
Abstract
Abstract In the present work the superalloy Inconel 718 manufactured by selective laser melting (SLM) was investigated with focus on micro-structural damage evolution under both monotonic and cyclic loading conditions. Material testing and characterization reveal significantly accelerated damage evolution of the SLM material, in comparing with the forged Inconel 718. An accumulated plastic strain based damage model was proposed to predict the damage evolution in the alloys under both monotonic and cyclic loading. The damage mechanism related to detrimental precipitate particles and porous defects in the material was discussed and considered in the model, which can predict both monotonic and cyclic material degradation processes with agreement.
