承担科研项目情况:

  

  图1 (a) 图解说明定向凝固过程晶粒竞争长大机制的Walton-Chalmers模型, (b) 汇聚生长双晶纵截面上的组织演化, (c) 发散生长双晶纵截面上的组织演化.

  通过定向凝固可以获得柱状晶组织,其机制遵循Walton-Chalmers模型,如图1(a)。该模型认为,汇聚生长晶粒A1和B的晶界和择优取向晶粒A1的枝晶生长方向平行。发散生长晶粒A2和B的晶界从择优取向晶粒A2向非择优取向晶粒B倾斜。非择优取向晶粒B左面被晶粒A1锁住,右面晶粒A2不断扩展过来,定向凝固一定距离后会消失,最终剩下择优取向晶粒A1和A2。但是近年来的研究发现,大量高温合金的实验结果不遵循Walton-Chalmers模型。在图1(b)所示的汇聚生长双晶高温合金中,其晶界并不与择优取向晶粒A的枝晶生长方向平行,而是从非择优取向晶粒B向择优取向晶粒A倾斜。竞争长大的结果是择优取向晶粒A消失,非择优取向晶粒B保留下来。在图1(c)所示的发散生长双晶高温合金中,其生长机制遵循Walton-Chalmers模型,晶界从择优取向晶粒A向非择优取向晶粒B倾斜。

  

  2 (a) 不同C含量单晶高温合金熔体与陶瓷型壳材料润湿角的原位测量, (b) 合金熔体冷却凝固后与陶瓷型壳材料接触面的宏观组织形貌.

  随着C含量的提高,合金熔体与陶瓷型壳材料的润湿角逐渐降低,合金与型壳材料发生界面反应的可能性增大。对于本工作中的合金,当C含量超过0.1%后,本来不与陶瓷型壳材料发生界面反应的合金也会出现界面反应。并且,界面反应的发生存在一个临界润湿角值。当润湿角大于该临界值时,合金与陶瓷型壳材料不发生界面反应;当润湿角小于该临界值时,合金与陶瓷型壳材料发生界面反应。

  

  3 不同Pt含量单晶高温合金在1100℃长期时效处理100h 后的TCP相析出情况(a) 5%Re+0%Pt, (b) 5%Re+1.5%Pt, (c) 5%Re+3%Pt.

  一般认为在含Re量较高的三代单晶高温合金中添加Pt族元素(如Ru、Ir、Pt)可以提高合金高温下长期时效组织的稳定性,抑制有害TCP相的析出。但是对一种含5%Re的三代单晶高温合金的研究结果表明,在该合金中添加Pt并不能提高其组织稳定性,反而会加快TCP相的析出。
