近十年来国外学者对某些合金(尤其是 Ni-Cr 合金)新型组织结构转交(K-状态)进行了不少的研究工作,但对 K-状态的本质并未得到肯定的一致看法.本文作者主要采用高温电阻方法研究证明,在 Fe-Gr-Al-Co 合金中也存在上述新型的组织结构转变,并研究了淬火处理和冷加工形变对80/20型 Ni-Cr 合金及 Kanthal 型 Fe-Cr-Al-Co 合金形成 K-状态动力学的影响.研究表明这些外界条件对 Ni-Cr 合金和 Fe-Cr-Al-Co 合金 K-状态形成的影响有所不同.本文就 K-状态的结构状态,形成过程以及外界条件对这个过程的影响进行了讨论.
In recent ten years, foreign scholars have done a lot of research work on the new K-state transfer of some alloys (especially Ni-Cr alloy), but have not got a positive consensus on the nature of K-state. The author mainly uses high-temperature resistance method to prove that there is also the above-mentioned new structure transformation in Fe-Gr-Al-Co alloy. The effect of quenching and cold working on the deformation of 80/20 Ni-Cr alloy and Kanthal Fe- Cr-Al-Co alloy formed K-state kinetics.The results show that these external conditions on the Ni-Cr alloy and Fe-Cr-Al-Co alloy K-state formation is different.In this paper, K- The influence of structure state, formation process and external conditions on this process are discussed.
