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。 -
The research results show that, from the viewpoint of second phase morphologies, there exist quite differences between the grain - type materials ( such as wc / bcu brazing deposit material, wrs1000 and 1zt tungsten carbide strengthening overlaying material, as well as the wear - resistant material of polymer adhesive coating etc. ), and the aggregation - type as well as dispersion - type ones ( such as zg35simn, wrd - 1 and khc - k2 depositing material ) in the wear - resistance and sand slurry abrasion mechanism. the sand slurry abrasion mechanisms are brought forward, of new wear - resistant materials with the features of grain - type second phase morphologies
研究發現，與聚合型、彌散型第二相的材料（如zg35simn 、 wrd ? 1和khc ? k2熔敷材料等）相比，顆粒型第二相的材料（如wc bcu釬焊熔敷耐磨材料、 wrs1000型耐磨材料、 1zt碳化鎢顆粒增強熔敷材料及ktc ? 1耐磨膠粘塗層材料等）在耐磨性能和磨損機理等方面均有不同，總結提出了以「顆粒型第二相」為特徵的耐磨新材料泥沙磨損機理。
