研究目的
Investigating the fabrication of 3D metallic glass (MG) structures using laser-induced forward transfer (LIFT) under ambient conditions, focusing on ZrPd-based metallic glass microstructures.
研究成果
The study successfully demonstrates the LIFT printing of high-resolution 3D MG structures under ambient conditions, with over 95% amorphous metal phase. The method's high resolution and noncontact nature make it a valuable technique for additive manufacturing of MG-based devices.
研究不足
The study is limited to ZrPd-based metallic glass and does not extensively explore the mechanical properties of the printed structures or the potential for other MG compositions.
1:Experimental Design and Method Selection:
The study employs LIFT for the fabrication of 3D MG structures, utilizing the inherent high cooling rates of the process to achieve amorphous metal phase formation.
2:Sample Selection and Data Sources:
ZrPd-based metallic glass is chosen for its superior mechanical properties and resistance to corrosion.
3:List of Experimental Equipment and Materials:
A nanosecond pulse duration fiber laser with emission at 532 nm is used for LIFT printing.
4:Experimental Procedures and Operational Workflow:
The printing involves focusing the laser on a metal layer interface to jet microdroplets onto a receiver substrate, forming 3D structures.
5:Data Analysis Methods:
X-ray diffraction (XRD) and transmission electron microscopy (TEM) are used to analyze the amorphous content and structural properties of the printed MG.
