Processing and Behavior of Fe-Based Metallic Glass Components via Laser-Engineered Net Shaping Metallurgical and Materials Transactions A B. Zheng1, Y. Zhou1, J. E. Smugeresky2 and E. J. Lavernia1 (1) Department of Chemical Engineering and Materials Science, University of California, Davis, CA 95616, USA (2) Sandia National Laboratories, Livermore, CA 94551-0969, USA Abstract In this article, the laser-engineered net shaping (LENS) process is implemented to fabricate net-shaped Fe-based Fe-B-Cr-C-Mn-Mo-W-Zr metallic glass (MG) components. The glass-forming ability (GFA), glass transition, crystallization behavior, and mechanical properties of the glassy alloy are analyzed to provide fundamental insights into the underlying physical mechanisms. The microstructures of various LENS-processed component geometries are characterized via scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and transmission electron microscopy (TEM). The results reveal that the as-processed microstructure consists of nanocrystalline α-Fe particles embedded in an amorphous matrix. An amorphous microstructure is observed in deposited layers that are located near the substrate. From a microstructure standpoint, the fraction of crystalline phases increases with the increasing number of deposited layers, effectively resulting in the formation of a functionally graded microstructure with in-situ-precipitated particles in an MG matrix. The microhardness of LENS-processed Fe-based MG components has a high value of 9.52 GPa. [ Last edited by hslining on 2009-9-21 at 23:23 ] |
