摘要

Sn-Bi合金微观组织形貌中Bi相的晶粒尺寸、数量、形状等特征参数对焊料的力学性能和焊接性能有较大影响

有必要对其进行定量分析。在LabVIEW平台下开发了金相图像的增强、滤波、阈值分割等预处理程序

并实现了金相组织的颗粒度、占比、轴长等参数的统计分析。结果表明

该系统能够快速、高效地对Sn-Bi合金及其他材料的金相组织进行筛选和定量分析

为焊料的韧化机制研究提供参考。

Abstract

The grain size

quantity

shape and other characteristic parameters of Bi phase in the microstructure of Sn-Bi alloy have great influence on the mechanical properties and welding properties of solder

so it is necessary to carry out quantitative analysis. The preprocessing program of metallographic such as image enhancement

filtering and threshold segmentation was developed under the LabVIEW platform

and the statistical analysis of the particle size

ratio and axial length of the metallographic structure was realized. The results show that the system can screen quickly and efficiently and analyze quantitatively the microstructure of Sn-Bi alloy and other materials

providing a reference for the research of toughening mechanism of solder.
