acid wash 酸洗〔一種用氯溶液洗滌牛仔褲等的方法〕。

acid-fast

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在鈹中的分布狀態對_ ( mys )的影響更大。沿晶界、晶內彌散分布的較細小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。
