In this study, nanocrystalline TiAlV alloys were synthesized using the mechanical alloying technique with a high-energy planetary ball mill from pure Ti, Al, and V powders. Various methods, including Vibrating Sample Magnetometry (VSM), Scanning Electron Microscopy and Energy Dispersive Spectroscopy (SEM-EDS), and X-ray Diffraction (XRD), were employed to characterize the synthesized alloys and study their magnetic behavior, morphology, microstructural and structural properties, respectively. Following the XRD analysis, new phases were confirmed, and a significant reduction in crystallite size from 48.73 to 9.38 nm was observed. Moreover, an increase in lattice strain from 0.15% to approximately 0.81% was noted after 60 h of milling. The EDS analysis gave remarkable results, showing the lack of magnetic iron particles before milling. However, after milling, the EDS spectrum revealed the presence of these magnetic iron particles with varying concentrations. This important observation highlights the profound impact of the mechanical alloying process on the sample composition. It emphasizes the sensitivity of EDS analysis by detecting even subtle changes in the elementary composition of a material. A sensitive approach was employed to monitor the progression of the nanocrystalline alloy and identify any potential defects arising during the mechanical milling. A vibrating sample magnetometer was utilized to achieve this objective. This method is highly effective at capturing even subtle changes that may occur during milling, allowing for an accurate evaluation of the chemical composition and integrity of the alloy. This technique made it possible to detect the presence of magnetic particles whose magnetic properties varied from time to time, indicating a change in magnetic behavior due to the reduction in the size of these particles caused by the collision between the steel balls and the milled powder particles. The results suggest that non-destructive magnetic testing using a VSM can be used to monitor the state of the nanocrystalline alloy.

在这项研究中，采用机械合金化技术和高能行星球磨机，由纯 Ti、Al 和 V 粉末合成了纳米晶 TiAlV 合金。采用振动样品磁力测定 (VSM)、扫描电子显微镜和能量色散光谱 (SEM-EDS) 和 X 射线衍射 (XRD) 等多种方法来表征合成合金并研究其磁性行为、形貌、微观结构和分别是结构特性。XRD 分析后，确认了新相，并观察到微晶尺寸从 48.73 nm 显着减小至 9.38 nm。此外，研磨 60 小时后，晶格应变从 0.15% 增加到约 0.81%。EDS 分析给出了显着的结果，显示研磨前缺乏磁性铁颗粒。然而，研磨后，EDS 光谱显示存在不同浓度的磁性铁颗粒。这一重要的观察结果凸显了机械合金化过程对样品成分的深远影响。它通过检测材料基本成分的细微变化来强调 EDS 分析的灵敏度。采用灵敏的方法来监测纳米晶合金的进展并识别机械铣削过程中出现的任何潜在缺陷。利用振动样品磁力计来实现这一目标。该方法可以非常有效地捕获铣削过程中可能发生的细微变化，从而可以准确评估合金的化学成分和完整性。该技术可以检测磁性颗粒的存在，其磁性随时间变化，表明由于钢球和研磨粉末颗粒之间的碰撞导致这些颗粒尺寸减小，从而导致磁性行为的变化。结果表明，使用 VSM 进行无损磁力测试可用于监测纳米晶合金的状态。
