“Anisotropic Microstructure, Nanomechanical, and Corrosion Behavior of Direct Energy Deposited Ti-13Nb-13Zr Biomedical Alloy” Summary: • The present study investigates the anisotropic microstructure, nanomechanical, and corrosion behavior of Ti–13Nb–13Zr biomedical alloys, which were fabricated using InssTek's DED Technology. •The specimen was additively manufactured under an Ar atmosphere. There are no powder particles on surfaces and shows uniform Ti, Nb, and Zr distribution without any segregation and precipitation, which indicates the as-deposited TNZ alloys are of good quality. •Analysis results of nanomechanical behavior show a very high creep exponent and corrosion resistance was superior to commercial Ti–6Al–4V in the same solution. DED is an effective way to fabricate Ti–13Nb–13Zr biomedical alloy with uniform distributions of elements and fewer defects.

“Characteristics of 3D Printed Functionally Graded Material for Replacement of Dissimilar Metal Weld in Nuclear Reactor” - Summary : • This Study tried to fundamentally remove dissimilar metal welds at the connections between low alloy steel parts and stainless steel piping in a nuclear reactor by replacing it with FGM manufactured by InssTek's Technology. • 5 layer FGM was manufactured using powder mixed in such a way that the fraction of ferritic phase was Reduced by 25% in 4 steps from 100% to 0%. The content of Cr, Ni, and Mo decreased linearly as the ratio of low alloy steel decreased, confirming that the intended gradient composition material was obtained. • It is observed that CTE tended to increase as the austenite content increased in FGM. The gradual change of coefficient of thermal expansion in a FGM showed that the additive manufacturing was effective for preventing an abrupt change in thermal expansion properties throughout their layers.

“Microstructural evolution and mechanical properties of functionally graded austenitic–low-carbon steel produced via directed energy deposition” Highlights: • This study investigated the FGM via InssTek's Technology as an alternative to the existing reactor pipe joining method and designed an FGM comprising austenite SS316L and low-carbon steel. • 5 layers with different compositions were produced. The bottom layer was deposited using 100% low-carbon steel on an S45C carbon steel plate. The following 3 layers were deposited using low-carbon steel and SS316L in weight ratios of 75:25, 50:50, and 25:75. The top was deposited using 100% SS316L powder. Delamination and cracking didn’t occur. • The OM and SEM images of the cross-sectional microstructure of the as-prepared FGM viewed perpendicular to the building direction showed no micro-cracks, delamination, or unmelted powder particles. In addition, EDS analysis indicated that the composition of each layer was relatively uniform, and no major precipitation was observed.

“Material Research with InssTek” - Summary : • This study reports on the rapid alloy screening of Ni–Co–Ti–Al–Mo superalloys with high thermal stability and specific yield stress by using InssTek's Technology. • 50 superalloys of various compositions were produced using InssTek MX-Lab (DED machine with 6 powder feeders) and single elemental powders of Ni, Co, Ti, Al, and Mo. The deposited superalloys were screened for the presence of γ/γ' microstructures and their respective γ' solvus temperatures. • Alloy compositions were controlled by varying each powder feed rate, and deposition time was 8 times faster than the casting process. The newly developed Ni–Co-based superalloy discovered by DED shows the outstanding balance of γ' solvus temperature, microstructural stability, and specific yield stress.

Through this, the industrial applicability of surface coating using HMS powder for maximizing wear resistance has been demonstrated. • Inconel 718 powder was deposited onto the substrate of STS316L, and then HMS powder was deposited according to different DED conditions. Defects such as cracks or delamination were not observed at the boundary between heterogeneous materials. • A wear test was conducted for the deposited HMS specimen, wear characteristics varied depending on load and RPM. Based on these results, the most effective wear conditions for applying HMS coating could be identified.

“Material Research with InssTek” - Summary : • This study compares the regular DED and the application of in-situ ultrasonic vibration to the melting pool to determine the effect of ultrasonic vibration in the process of manufacturing AA7075 with DED. • Experiments were carried out under 2 scenarios – with and without ultrasonic vibration. In the ultrasonic-assisted DED process, in-situ ultrasonic vibration was introduced through an AA7075 substrate, and then AA7075 powders were melted and deposited on the substrate simultaneously. • The improved microstructure contributes to the development of superior mechanical properties. Consequently, the integration of DED with ultrasonic vibration enhances the mechanical performance of AA7075 alloy. Reference: https://www.tandfonline.com/doi/full/10.1080/17452759.2023.2301482
