Methods of microyield strength testing are described. The results of microyield strength measurements on hot isostatically pressed beryllium are presented as well as preliminary TEM examination of material in the as-pressed condition. Error trend data from instrument test is compared to errors predicted from a postulated microcreep law and uniaxial microcreep data. Results of creep analysis on a simple structural shape are presented.
