摘要
研究了钇含量对Fe-20Cr-4Al-(0—0.73wt-%)钇合金室温力学性质的影响。结果表明,随钇含量增高,拉伸试样的均匀变形能力略微降低,断裂强度和预缩后的变形量显著下降。这些变化与合金中脆性含钇相对变形和断裂过程的影响有关。控制冶金工艺能改变含钇相的形态。
With the increase of Y content in the Fe-20Cr-4Al-Y alloy, the uni-form deformability of tensile specimens was found to be slightly decreased, as wellas, the fracture strength and reduction of area after necking remarkably dropped.This seems to be dependent upon the brittle phase containing Y. The behaviour ofY-containing phase may be improved by adjusting the metallurgical technologicalprocess.
