in this pic you see microstructure of Haynes 188 after produced of it ingot (homogenize in 1200C then water quench). incidentally this pic is for before of it rolling process.what is carbide type in grain boundary and grain? please guide me?
I mentioned the book edited by Henry Chandler in my last answer. The information you want is on page 103. Page 102 has TTP diagram from which you can figure out what carbide you get by cooling at different rates, at what temperatures they form, etc. Attached is information on buying this book if your library does not have it.
In case you have had any difficulty in locating the TTP diagram I have attached it for your convenience. This should help you is planning the annealing in terms of the temperature and time.
dear Malur Srinivasan thank you so much. you give me an important information about heat treatmen of Haynes 188. i have very pleased.
