  1. Beryllium powders with the same particle size and various contents of beo were prepared by pre - sintering - acid washing processes initiatively and the influence of beo alone on o mys of beryllium was observed and some new results have been obtained - compared with the content of beo, the distribution of beo in beryllium has more critical influence on mys ; finely dispersed beo along the grain boundaries and in the matrix results in the dispersion strengthening of beryllium matrix and thereby the higher mys value ; on the contrary, the coarser beo particles clustering on the grain boundaries results in negative influence on o mys
