粗晶粗粒
英文
coarse grains-
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
開創性地用預燒結? ?酸洗工藝制備了相同粒度、不同beo含量的鈹粉，從而開展了beo含量單獨對鈹材_ （ mys ）影響的研究，得出一些新的結果：與beo含量相比， beo在鈹中的分佈狀態對_ （ mys ）的影響更大。沿晶界、晶內彌散分佈的較細小beo對基體鈹有彌散強化作用，使_ （ mys ）即較高；如果beo較粗大地成簇狀聚集在晶界，反而對_ （ mys ）有不良的影響。Effect of microalloy element on the grain coarsening behavior of q345 steel
