Abstract

This study examines how spark plasma sintering (SPS) temperature and heating rate (in the presence of zirconium element) affect the densification behavior, microstructure, mechanical properties, and tribological behavior of Fe₇₅Si₁₅B₅Zr₅ metallic glass. Sintering took place in the supercooled liquid region of the metallic glass powder. The Archimedes method measured densification behavior. Scanning electron microscopy (SEM) provided detailed microstructural information and allowed qualitative evaluation of fracture toughness. X-ray diffraction handled phase analysis and quantified crystallization in the amorphous phase. Ball-on-disk wear testing evaluated tribological behavior, and Vickers microhardness testing assessed mechanical properties. Results revealed that higher sintering temperature increased both the crystallization degree of the amorphous phase and the densification rate. In contrast, heating rate produced mixed effects on crystallization and densification. The sample sintered at the highest temperature with the lowest heating rate exhibited the best fracture resistance and achieved the highest microhardness value of 1096 HV1. Across all samples, delamination of the tribological oxide layer was determined as the main wear mechanism.

火花等离子烧结固结铁基大块金属玻璃的显微组织演变、力学性能和耐磨性

本研究考察了火花等离子烧结（SPS）温度和加热速率（在锆元素存在的情况下）对Fe75Si15B5Zr5金属玻璃的致密化行为、微观结构、力学性能和摩擦学行为的影响。烧结发生在金属玻璃粉末的过冷液区。阿基米德方法测量致密化行为。扫描电子显微镜（SEM）提供了详细的微观结构信息，并允许定性评价断裂韧性。x射线衍射处理物相分析和非晶相的定量结晶。球盘磨损测试评估摩擦学行为，维氏显微硬度测试评估机械性能。结果表明，烧结温度越高，非晶相的结晶程度越高，致密化速度越快。加热速率对结晶和致密化的影响是混合的。在最高温度和最低加热速率下烧结的试样具有最佳的抗断裂性能，显微硬度达到最高的1096 HV1。在所有样品中，摩擦学氧化层的分层被确定为主要的磨损机制。
