Damage Evolution Simulations

“Damage Evolution Simulations via a Coupled Crystal Plasticity and Cohesive Zone Model for Additively Manufactured Austenitic SS 316L DED Components – Metals 2022” - Highlights • This study represents damage simulation for SS316L using DED additive manufacturing using InssTek's DMT Technology. • Regarding the impact of the number of melt pools on the tensile properties, melt pool size controlling can be prone as a significant way to achieve the required features. • The proposed methodology is expected to yield satisfactory outcomes in dealing with the grain morphology and melt pool size effects on the mechanical behavior, and it is believed that it will provide complementary insights into the material design concept and pave the way for the broader use of DED in the industry. Reference: Metals is an international, peer-reviewed, open access journal published monthly online by MDPI.

C-103 (Nb-based alloy) Deposition Test

InssTek has developed process parameters of the C-103 Nb alloy, which is widely used in the aerospace industry. Based on material research and AM process parameter, we are continuously challenging in the aerospace applications. - 1 ton Rocket Nozzle Extension Propoerties Test - The possibility of C-103(Nb-based alloy) deposition in an atmospheric environment

Blue Laser Cladding Test – Inconel 625 cladding on Cu alloy

Blue Laser Cladding Test – Inconel 625 cladding on Cu alloy The possibility of IN625 cladding on Cu alloy using blue laser was confirmed. We tried to find optimal process parameter for these combination of materials and try to apply this combination of materials to the final product in real application.

TiAl (Ti-48Al-2Cr-2Nb alloy) Deposition Test & Challenge

TiAl (Ti-48Al-2Cr-2Nb alloy) Deposition Test & Challenge ◇ Material (TiAl) Feature - It has excellent mechanical properties (tensile strength 500 MPa at 800°C)at a high temperature (600°C or higher), oxidation resistance, and corrosion resistance. - Due to its low density (about 4.0 g/㎤), it is possible to reduce the weight of parts. - This material is used especially for power generation turbine blades, aviation LPT blades, and automotive turbocharger wheels. ◇ AM Research We were able to identify crack-free microstructure through the Hot isostatic pressing (HIP) process. We will challenge complex shapes and huge sizes through the study of additive manufacturing processes.

Stabilize of Blue Laser Deposition Technology

InssTek is able to stabilize Blue Laser Deposition Technology in short time. - This research was able to done in very short time because InssTek has in-house Optic Module. - Blue Laser's potential is unlimited when combined with InssTek`s PCM-Multi (Accurate & Hexa Powder Feeder) and MIXO Pro (5Axis AM CAM software)

Recyclability of Metal Powder in Direct Energy Deposition

Recyclability tests with three different metal powders. - As a result, there was no significant difference between recycled powder and virgin powder in various indicators. (Powder was recycled after sieving) - The mixing ratio of recycled powder and virgin powder did not cause a significant difference in the results. - More than 95% of powder after DED process can be used as a recycled powder.

Pure Aluminum Deposition Test

Manufacturing possilbility confirmed : Pure Aluminum with both IR laser and Blue laser - Deposition tests of Pure Aluminum (UNS A91070) material were conducted with IR Laser and Blue Laser. - In general, aluminum is difficult to manufacture with an IR laser. InssTek secured the process parameter of Pure Aluminum through a delicate process (Both IR Laser & Blue Laser). - There was no defect inside of both samples and we are planning to do further research with two laser sources to adapt industrial cases.
