| 摘 要： | 用扫描俄歇探针（ＳＡＭ）结合真空热处理试验，研究了９５Ｗ-Ｎｉ-Ｆｅ合金的脆化 机理，发现烧结态合金中散布着氧的高浓度富集区，这是钨合金脆化的重要因素。１０００℃以 上的真空热处理可以消除氧高浓度富集区和降低界面氧浓度，使合金延性、韧性显著提高。

| Abstract: | The embrittling mechanism of 95W - Ni - Fe alloy has been researched by using Scanning Auger Microprobe(SAM) combined with heat treatment in vacuum. It has been found that high oxygen con- centration coalescent zones(HQCCZ) scattered in sintered state alloys. HOCCZ is an important embrittling fac- tor of the tungsten alloy. Heat treatment in vacuum over 1000℃ can eliminate OHCCZ, decrease oxygen con- centration at interfaces and allow evident enhancement of elongation and toughness of the alloy. |
