Metal DED AM HS Modeling and RSA

Heat Source Modeling and Residual Stress Analysis for Metal Directed Energy Deposition Additive Manufacturing - Highlights • This study evaluating heat source model for single and multi-track deposition by using InssTek's DMT Technology • The concentrated heat source does not require melt pool dimension measurement for thermal model simulation. Thus, it reduces the considerable time for preprocessing. • A good agreement was noticed for the concentrated heat source model melt pool, with an experimentally determined melt pool, using an optical microscope. * Written referring to the study

Functionally Graded Material Rocket Nozzle

“Functionally Graded Material Rocket Nozzle” The field of aerospace is an extreme environment. Each part of the Rocket Nozzle requires different characteristics. Recently InssTek successfully manufactured FGM Rocket Nozzle and proceed post-process. We have used our internal technology for the entire process, from testing for each alloy to obtaining process variables to designing and actual printing. ✔️Material: - Top: Al-Bronze - Bottom: SS316L ✔️Size: - Diameter: 420 mm - Height: 552 mm ✔️Deposition Time - 32 Hours

Aluminium Alloy & Aluminium + Ceramic MMC Wear Test

“Aluminium Alloy & Aluminium + Ceramic MMC Wear Test” The possibility of Aluminum manufacturing using InssTek's DED technology was studied. Pure Aluminum, Aluminum Alloy and Aluminum MMC were tested and their characteristics were compared through Wear Test. ✔️Test: - The ball on Disc Test was performed at 5 kgf / 30 min / 50 rpm with InssTek’s DED technology. ✔️Material: Pure Al Al 4000 series Al 6000 series Al + Al2O3 (MMC) ✔️Result: - The Friction Coefficient value of the aluminum + ceramic MMC was similar to the aluminum alloy. - Wear Quantity showed the best results than pure Al and Al-based alloys.

“Processing of Niobium-Alloyed High-Carbon Tool Steel via Additive Manufacturing and Modern Powder Metallurgy – Materials(2023)” - Highlights • This research adopted InssTek`s DED process to fabricate Niobium-Alloyed High-Carbon Tool Steel and compared it with modern method (Spark Plasma Sintering) • This work explores the potential of additive manufacturing for processing Nb-alloyed tool steel with a high content of carbon. • The hardness and wear resistance of the additively manufactured material was slightly higher than the Spark Plasma Sintered one. * Written referring to the study

Wear behavior of aluminum-matrix particle (TiH2 and ZrH2)

“Wear behavior of aluminum-matrix particle (TiH2 and ZrH2)-reinforced composite foam additively manufactured using directed energy deposition – Journal of Materials Research and Technology 25(2023)” - Highlights • This research adopted InssTek`s DED process to fabricate aluminum-matrix particle-reinforced composite form by   adding TiH2 and ZrH2 to AlSi10Mg. • Owing to the intermetallic compound formed upon the reaction between AlSi10Mg and foaming agent,   only a part of the aluminum matrix was removed due to wearing. • Wear test results showed that the deposited AlSi10Mg fabricated with ZrH2 had the best wear resistance.

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.

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.
