Quantification and Statistical Analysis of Microstructural Features in As-cast Ti-6Al-4V Titanium Alloy

摘要：

　　Based on microstructure of as-cast Ti-6Al-4V titanium alloy,an image processing to simplify model of β grain size,α lamella space was developed and a quantitative statistical method of β grain size,α lamella space in two-phase titanium alloys was established,with which β grain size and α lamella space of as-cast Ti-6Al-4V titanium alloy with different plate thickness were analyzed.The relationship between β grain size,α lamellar space and cast plate thickness was discussed.The results show that β grain size and α lamellae thickness nearly linearly increase as plate thickness increasing.β grain size has normal distribution and with cast plate thickness increasing,the dispersion gets larger.
