Evaluation of Ti-Mn Alloys for Additive Manufacturing Using High-Throughput Experimental Assays and Gaussian Process Regression.

摘要: Compositionally graded cylinders of Ti-Mn alloys were produced using the Laser Engineered Net Shaping (LENS™) technique, with Mn content varying from 0 to 12 wt.% along cylinder axis. The subjected different post-build heat treatments produce a large sample library a-b microstructures. microstructures in studied back-scattered electron (BSE) imaging scanning microscope (SEM), and their mechanical properties evaluated spherical indentation stress-strain protocols. These protocols revealed that exhibited features averaged chord lengths range 0.17-1.78 mm, beta 20-83 vol.%. estimated values Young's moduli tensile yield strengths found vary ranges 97-130 GPa 828-1864 MPa, respectively. combined use LENS technique was facilitate rapid exploration material process spaces. Analyses correlations between conditions, several key microstructural features, measured performed via Gaussian regression (GPR). data-driven statistical models provided valuable insights into underlying these variables.
