Engmoh, I reccomend you take a look in www.matweb.com there is a database with a lot of materias and their properties at least mechanical. But for Recrystallization, the best way is searching in papers. Also for recrystallization the Humpreys (book) is an excellent reference.
if you do not find the answer from researching .you have to do experiment test by tensile test and take the log for stress and strain to determine n and k
