| Abstract Scope |
This work proposes a method to combine the variation in composition of a Ti-Cr graded material in one axis, along with the change in thermal history in the other axis. A Ti-Cr gradient sample was produced using a LENSŪ AM system with a specific geometry, followed by a heat treatment in the thermo-mechanical simulator Gleeble to generate different thermal histories at specific locations within the sample. The sample was characterized with spatially resolved acoustic spectroscopy (SRAS) to map the surface acoustic wave velocity across the entire sample. SEM imaging and image analysis software were used to characterize the microstructure at different locations throughout the sample and compared to SRAS data. Microhardness data was obtained from the 2D sample. Finally, a finite element model was created to simulate the Ti-Cr graded sample going through the differential heat treatment process, and to correlate all experimental data with their thermal histories. |
