Abstract—

We have studied the phase composition and texture of a Pd–Cu solid solution with a nearly equiatomic composition in different steps of the preparation of membrane foil by rolling to 300, 175, 100, and 20 μm and 7-μm-thick foil produced by magnetron sputtering of a target having the same composition as the foil. We have identified orientation relationships between the β- and α-phases in the as-prepared two-phase structures and demonstrated that, after heating to 600°C and subsequent cooling, the ordered solid solutions (β-phase) prepared by the two processes, have identical textures, which can be understood in terms of the transformation mechanism.

β↔α相变的可逆性是决定Pd-Cu膜箔结构是否取决于箔制备过程的关键因素

摘要-

我们已经研究了在制备膜箔的不同步骤中，通过轧制成300、175、100和20μm厚7μm的铝箔而制备的具有几乎等原子组成的Pd-Cu固溶体的相组成和织构。具有与箔相同成分的靶的磁控溅射。我们已经确定了所制备的两相结构中β相和α相之间的取向关系，并证明了加热至600°C并随后冷却后，通过两种方法制备的有序固溶体（β相）具有相同的纹理，可以通过转换机制来理解。
