“…However, the HAZ of the AFSD substrate displayed a significantly higher hardness than that of the L-DED. Similar hardness profiles for a laser-clad AerMet 100 were observed by Aditya et al, with a hardness range of 500 to 520 HV [28]. Likewise, Ran et al reported hardness values ranging from 445 to 536 HV depending on location in an L-DED tower build [26].…”

“…Wrought AerMet 100 has a minimum hardness of 600 HV, exceeding that of the deposited material. However, the work by Aditya et al also observed a 100 HV increase in hardness due to a post cladding heat treatment, suggesting potential increases in hardness capable in the current work [28]. Tensile stress-strain results for quasi-static (0.001 s −1 ) and high-rate (2500 s −1 ) can be seen in Figure 6.…”

“…With high production costs and long lead times through traditional manufacturing, AM can be a great alternative to produce final part geometries of ultrahigh-strength material systems. The resulting microstructural and mechanical performance of AerMet 100 deposited through L-DED and wire arc additive manufacturing (WAAM) have been studied previously along with L-PBF [8,[25][26][27][28][29]. Currently, no work has been performed to better understand how AFSD may change the deposited material system and the AerMet 100 strain-rate dependence.…”

Quasi-static and high-rate tensile experiments were used to examine the strain rate sensitivity of laser-directed energy deposition (L-DED)- and additive friction stir deposition (AFSD)-formed AerMet 100 ultrahigh-strength steel-additive manufactured builds. Electron backscattered diffraction (EBSD) revealed similar as-deposited grain sizes between the two AM processes at approximately 24 μm and 17 μm for the L-DED and AFSD samples, respectively. The strain hardening rate, θ, revealed little change in the overall hardening observed in the L-DED and AFSD materials, with a consistent hardening in the quasi-static samples and three identifiable regions in that of the high-rate tested materials. The L-DED deposited materials displayed average ultimate tensile strength values of 1835 and 2902 MPa for the 0.001 s−1 and 2500 s−1 strain rates, respectively and the AFSD deposited materials displayed ultimate tensile strength values of 1928 and 3080 MPa for the 0.001 s−1 and 2500 s−1 strain rates, respectively. Overall, the strength for both processes displayed a positive strain rate sensitivity, with increases in strength of ~1000 MPa for both processes. Fractography revealed significant solidification voids in the laser DED material and poor layer adhesion in the AFSD material.

“…Other studies focused their works on die repair by depositing harder alloys than the initial die material [7], [8]. Aditya et al [9] tried to clad a Co-Ni secondary hardening steel in readiness for the repairing of components such as pinion housing shafts or gears. In our case, the alloy used for repairing is Inconel718 (IN718).…”
