稀土夹杂物对D6AC超高强度钢力学性能的影响

Effects of Rare Earth Additive on Sintering of Diamond Sawblade Segments

本文研究了稀土夹杂物含量对Ｄ６ＡＣ钢强度和塑性的影响，得出了夹杂物的体积百分率与断面收缩率的定量关系式。从夹杂物尺寸和数量方面探讨了对Ｄ６ＡＣ钢韧性的影响。并提出了改善性能的途径。

Influences of rare earth additive on the sintering of diamond sawblade segments have been discussed from the retention of bond to diamond crystals and effects of sintering on diamond property and bond mechanical properties. The experimental results reveal that rare earth additives have a role of pre oxidation and activation during sintering diamond sawblade segments, so the wear performance of sawblade segments was increased greatly by using rare earth additives and these additives will be more important for sintering segments used in multiblades.
