High-energy beam additive manufacturing (HEB-AM) of nickel-based superalloys has shown great application potential in aerospace and other fields. However, HEB-AM of nickel-based superalloys faces serious cracking problems because of the unique characteristics of superalloys, and this has become the most significant bottleneck restricting their application. In this review, the current research status related to the types, formation mechanisms, and suppression methods of cracks in nickel-based superalloys produced by HEB-AM is described. The initiation and propagation mechanisms of cracks and their multiple influencing factors are also analyzed and discussed. Then, several possible research directions to solve the cracking problems in nickel-based superalloys produced by HEB-AM are outlined.

To overcome this challenge, one approach that has received considerable attention is process monitoring accompanied by mitigation strategies to improve the forming accuracy and repeatability. This study outlines the current understanding of the formation mechanism of common geometrical defects and discusses techniques to monitor the process and mitigate defects.

In this study, the effect of the process parameters of selective laser melting (SLM) on the surface morphology, relative density, microstructure, and mechanical properties of Al-Mg-Sc-Zr high-strength aluminum alloys with low <em>Sc</em> content was systematically investigated. The results show that the energy density has an important effect on the surface quality and densification behavior of the Al-Mg-Sc-Zr alloy during the SLM process. As the energy density increased, the surface quality and the number of internal pores increased. However, the area of the fine-grained region at the boundary of the molten pool gradually decreased. When the laser energy density was set to 151.52 J/mm³, a low-defect sample with a relative density of 99.2% was obtained. After heat treatment, the area of the fine grains at the boundary increased significantly, thereby contributing to the excellent mechanical properties. The microstructure was characterized by a unique “fan-shaped” heterogeneous structure. As the energy density increased, the microhardness first increased and then decreased, reaching a maximum value of 122 HV_0.3.

The tensile properties and shape-memory effects of the NiTi alloys prepared using the optimized process were clarified. The relationship between the change in temperature and the shape recovery process of the deformed structure under electrical excitation was investigated. The results show that the suitable processing window for ensuring the forming quality without noticeable distortion and macro cracks depends on the laser parameters. In both the <em>X</em> and <em>Y</em> directions, the measured dimensions increased with an increase in laser power and first decreased and then stabilized with an increase in scanning speed. The XRD results showed that all the as-built samples consisted of B2 austenite and B19’ martensite phases and Ni₃Ti. Mechanical tests suggested that excellent tensile properties with a tensile strength of 753.28 MPa and elongation of 6.81% could be obtained under the optimal parameters of 250 W and 1200 mm/s. An excellent shape-recovery rate of 88.23% was achieved under the optimal parameters. Subsequently, chiral lattice structures were successfully fabricated by laser powder bed fusion (LPBF) under the optimal parameters, and a shape-recovery rate of 96.7% was achieved under electrical actuation for a structure with a pre-compressed strain of 20%.

First, the morphology characteristics demonstrate that the manufacturing errors of sheet-based structures with diverse porosities are comparable, and semi-melting powders as well as the ball phenomenon are observed; in comparison, strut-based samples exhibit cracks and thickness shrinking. Second, the mechanical properties indicate that the sheet-based structures have a greater elastic modulus, energy absorption, and better repeatability compared to strut-based structures. Furthermore, layer-by-layer fracturing and diagonal shear failure modes are observed in strut-based and sheet-based structures, respectively.

This work reviews the recent studies on internal defects in SLM, presenting the main internal defects of SLM as impurities, lack of fusion, gas pores, and micro-crack. These internal defects occur on the various phenomena in the laser-powder-melt pool (LPMP) stage. The formation of SLM internal defects is mainly affected by oxidation, denudation, balling, spatter, and keyholes; here, balling, spattering, and the keyhole phenomenon are the main factors causing internal defects in LPMP. Hence, this paper focuses on reviewing the balling effect, spatter behavior, and keyhole phenomenon, introducing the action mechanism of the above three phenomena under different process conditions. Additionally, the spatter behavior when forming internal defects is proposed. This review also considers the correlation between the spatter behavior and keyhole phenomenon and makes an important contribution to understanding and reducing SLM internal defects.
