Case Study.17_Multi-Material Research[AlBronze+IN718]

“Multi-Material (Al Bronze + IN718) test with MX-Lab” In this case study, a multi-material sample of Ni-based alloy and Copper-based alloy was manufactured by 3D printing (MX-Lab), and mechanical properties were tested to confirm the possibility of using multi-material of both materials. Al Bronze + IN718 multi-material specimens could be easily manufactured using the MX-Lab. Ni-based alloy is widely used in extreme environments such as aerospace, power generation, and the oil & gas industry. However, the restricted thermal conductivity constrains the application of Ni-based alloys in high heat flux cases. The joining of materials with high thermal conductivity such as copper alloy to Ni-based alloys can improve upon this limitation to adapt for temperature-sensitive requirements. The specimens were subjected to a tensile test according to ASTM E8 after machining. As a result of the tensile test for specimens, no fracture occurred at the bonding interface. The fracture was occurred in the Al Bronze part because of the lower tensile strength of Al Bronze than IN718.

Case Study.16_FGM Research [Stellite6+SS316L]

Material research report with MX-Lab(CVM powder feeding system) The component analysis of five Stellite6 + SS316L FGM(Functionally Graded Material) samples stacked at once shows a similar compositional distribution. Through this test, we confirmed that the feeder of MX-Lab can supply and control powder consistently. By producing FGM through the CVM powder feeding system of MX-Lab, samples of various compositions can be simultaneously manufactured, which can reduce the opportunity cost by reducing alloy design and verification time. In addition to FGMs(Functionally Graded Materials) methodologies, it is possible to implement other multi-material composition methods such as MMCs (Metal Matrix Composites), and HEAs(High Entropy Alloys).

Case Study.12_FGM Research [Albronze + SUS316L]

See the additional new powerful features of MX-Lab. These new functions will help your material research to be easier and faster. ✔Auto Z Automatically adjusts the distance between the sample and nozzle to 9 mm in real time during deposition. Keeps the working distance constant for constant Bead growth. ✔Laser Power Control Function Sets the appropriate laser power for the material at the desired location based on the NC-Code when producing a multi material sample. Try researching new materials more easily and quickly with the new MX-Lab. This FGM demo shows how easy it is to study new materials with the MX-Lab equipment. In this demonstration, we started with a SUS316L base and gradually deposited the material to change to Albronze. After deposition, the sample was analyzed with SEM & EDS and have confirmed that the composition of the material gradually changed.

Case Study.6_FGM Research [IN625 + T800]

Technological limitations in this process are susceptibility of T‐800 to brittle fracture as well as significant thermal stresses due to rapid  cooling, which is an inherent attribute of laser techniques. Therefore, in this work, a number of steps that optimized the LENSTM process  and improved the metallurgical soundness of coatings are presented. Employing volume and local substrate pre‐heating resulted in the formation of high quality coatings devoid of cracks and flaws.
