How to Control the Crystallization of Metallic Glasses During Laser Powder Bed Fusion? Towards Part-Specific 3d Printing of in Situ Composites
Abstract
This paper presents a strategy to create highly oriented crystalline-amorphous composites during the laser powder bed fusion (LPBF) process. The well-known AMZ4 (Zr 59.3 Cu 28.8 Al 10.4 Nb 1.5 ) and equiatomic CuZr amorphous alloys were processed by a novel two-stage melting strategy followed by ultra-high-pressure hot isostatic pressing (HIP).The experiments show that with fine-tuning laser parameters, purely amorphous material, and laminate amorphous-crystalline composites with a part-specific microstructural design, can be created. Novel opportunities for nonequilibrium phase distribution design were provided by controlling local crystallization in the heat-affected zone (HAZ) and avoidance of heat accumulation. Moreover, the porous amorphous material was densified without crystallization using HIP at a temperature near the supercooled liquid region.The distribution of the crystalline phase created during LPBF and crystallization on pre-induced nuclei during HIP was proven to be a critical factor for composite properties. The influence of crystalline-amorphous layers orientation on mechanical properties was revealed in wear and bending tests. Functional components were manufactured, showing outstanding possibilities in the design for additive manufacturing (DfAM) with a microstructure-designed composite.
