Effect of TiC on the high-temperature oxidation behavior of WMoTaNbV refractory high entropy alloy fabricated by selective laser melting

Lan Chen et al.

Summary: Refractory high-entropy alloys are expected to be a new generation of high-temperature materials due to their high melting points and excellent high-temperature properties. In this study, selective laser melting (SLM) was used to prepare WMoTaNbV and TiC/WMoTaNbV-based alloys, and the influence of SLM process parameters on the alloy's surface morphology, internal defects distribution, and microstructure was thoroughly analyzed. The study also investigated the long-term high-temperature oxidation behavior of the two alloys at 600 degrees C. The results showed that process parameters significantly affected the surface quality and internal defects of the refractory high-entropy alloys. Optimizing the process parameters improved the surface roughness and reduced cracks in the TiC/WMoTaNbV alloy. The two alloys had different microstructures, and the main oxidation products were identified. The addition of TiC particles effectively prevented the alloy from serious oxidation, and the TiC/WMoTaNbV-based alloy exhibited improved oxidation resistance due to its cellular structures, carbides, and TiO2 phase.

Tuning the mechanical properties of powder bed fusion printed CoCrFeNiMn high-entropy alloys by annealing and hot isostatic pressing

Gongwen Gan et al.

Summary: Powder bed fusion (PBF) and other additive manufacturing (AM) techniques have potential for research and processing industry. Two post thermal treatment approaches, based on annealing and hot isostatic pressing (HIP), are proposed to enhance the mechanical properties of CoCrFeNiMn HEA printed using PBF technology. Both approaches result in almost fully dense structures with over 98% relative density. The post treatments significantly improve the plasticity of PBF printed HEAs, leading to an increase in elongation and tensile properties, attributed to the synergistic effect of dislocation and nano-twin crystal deformation. In conclusion, these post thermal treatments are of great significance for the development of HEA with excellent mechanical properties, with HIP offering optimal structure and performance.

Exploring multicomponent eutectic alloys along an univariant eutectic line

Xi Jin et al.

Summary: This work proposes a method to design multicomponent eutectic alloys with disordered face-centred cubic (FCC)/disordered body-centred cubic (BCC) structures along the univariant eutectic line. Based on this method, four FCC/BCC-structured MCEAs in Co-Cr-Fe-Ni-V systems with similar lamellar microstructures but different tensile properties have been successfully designed and prepared. The Cr41Ni39Co10V10 alloy exhibits the highest 0.2% offset yield strength of 591 MPa, ultimate tensile strength of 1076 MPa, and considerable elongation of 10%. Nano-indentation tests reveal that the difference in yield strength is mainly attributed to the strength difference of the FCC matrix, while the BCC/ FCC strength ratio R* accounts for the difference in strain-hardening capability. This work is significant for the exploration of novel MCEAs with excellent properties.

Summary: 316L/CuCrZr functionally graded materials with grain size gradients and heterogeneous microstructures were prepared by laser powder bed fusion. The samples exhibited a gradient microstructure with ultrafine equiaxed grains sandwiched between micron-scale columnar grains. The dual-scale heterogeneous microstructure consisted of the BCC-alpha-Fe and FCC-epsilon-Cu phases, ensuring high shear and tensile strength of the samples. The formation mechanisms of the grain-size gradients and heterogeneous microstructures were discussed, and the additive manufacturing strategy for fabricating functionally graded materials with grain size gradients and heterostructures may open up new possibilities for materials design.

Selective laser melting of IN738 superalloy with a low Mn plus Si content: Effect of energy input on characteristics of molten pool, metallurgical defects, microstructures and mechanical properties

Luo Zhang et al.

Summary: IN738 superalloy has excellent high-temperature performance, making it attractive for aerospace applications, but its additive manufacturing via SLM faces challenges due to high crack susceptibility. By strictly controlling Mn + Si content in raw powder and optimizing the process, crack-free and nearly fully dense samples of IN738 with excellent mechanical properties were successfully obtained. High laser power was found to be more effective in shaping large melting depth and depth-to-width ratio under the same linear energy density, while different morphologies of the molten pool were observed throughout the entire LED range.

Displacive transformation as pathway to prevent micro-cracks induced by thermal stress in additively manufactured strong and ductile high-entropy alloys

Rui-di Li et al.

Summary: The study systematically investigated the micro-cracking behaviors and residual stresses of two high-entropy alloys prepared by selective laser melting. The equiatomic HEAs exhibited micro-cracks with tensile stress, while non-equiatomic HEAs were crack-free with compressive stress due to the displacive transformation during cooling. These findings provide useful guidance for designing strong, ductile, and crack-free alloys in additive manufacturing by tuning phase stability.
