“…The morphology of the printed parts can vary significantly from top to bottom, indicating the nonuniformity of the surface finish throughout the part (Pelzer and Hopmann, 2021). The morphology, being a crucial factor, can negatively affect the AM parts’ thermos-physical characteristics (Agrawal et al , 2021). As a result, further steps are used to enhance the morphological characteristics of AM parts (Joseph et al , 2018).…”

“…phase further enhanced the fatigue limit to 325 MPa in the stress-controlled fully-reversed bending fatigue tests. [225] Kuzminova et al [215] scrutinized the effect of annealing and machining on the stress-controlled fatigue of LPBF-fabricated CrFeCoNi alloy. The annealing process decreases the yield strength, thereby increasing the ratio of the ultimate tensile strength (σ UTS ) to yield stress (σ YS ), i.e., k ¼ σ UTS σ YS , from 1.2 in the as-built state to 1.4 after annealing.…”

“…Based on the economic and technical perspectives, MAM is adjudged to have opened up new opportunities for liquid rocket engine designs [5] and fabrication of turbine engine components like turbine blades with unique cooling designs/channels [6,7] in the power generation, aerospace and aviation industries. Currently, there is a concerted effort to maximise the full potential of this versatile technology by extending its usage to produce aerospace components/parts with or without functional grading [8]. The major barriers to the optimal utilisation of metal additive manufacturing technologies have been identified as the nonexistence of standard procedures on powder recyclability (required for direct cost reduction), meeting surface quality requirements and finishing features like internal lattices/pathways [9].…”
