What is the most reliable and accurate procedure to calculate the volume fraction (in %) of secondary phases induced in a material due to external conditions like welding, aging etc.
THANKS AND REGARDS.
In my study, I usually take more than 20 SEM or TEM images of the microstructure. Then we can calculate the the volume fraction (in %) of secondary phases using image processing software.
Thank you very much for the contributions sir Jian Peng Yusdel Díaz Ruipeng Guo
Actually I dont have much background and expertise in computational materials science like use of these methods. Ruipeng Guo Sir can you please specifically mention the image processing software? Can EBSD technique do the job as mentioned in the question where different phases can be selectively colored? Thank u.
The secondary phases are usually with small size, EBSD may be not a good choice. You can use Image Pro Plus if available.
