| 7. | And we also discovered there is no decreasing of the hardness on the surface of cr12 steel . it is due to dispersion harden by plentiful of alloy carbide and decreasing of residual austcnitc . these research work should provide some useful references for technicians in practice . at last , the program was also introduced
但在高合金钢cr12中发现硬度回落现象并不明显，这是因为本身该钢种的激光加工硬化带硬度并不大，另外高合金含量产生的弥散强化以及残余奥氏体的减少也是硬度回落小的一个原因。 |

| 9. | 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
开创性地用预烧结? ?酸洗工艺制备了相同粒度、不同beo含量的铍粉，从而开展了beo含量单独对铍材_ ( mys )影响的研究，得出一些新的结果：与beo含量相比， beo在铍中的分布状态对_ ( mys )的影响更大。沿晶界、晶内弥散分布的较细小beo对基体铍有弥散强化作用，使_ ( mys )即较高；如果beo较粗大地成簇状聚集在晶界，反而对_ ( mys )有不良的影响。 |
