项目摘要

During the two-year period of this project, the following achievements have been made.1. A new deposition apparatus with better vacuum has been constructed using the equipment budgets of this Grant-in-Aid.2. Copper and iron were chosen, one as a deposit crystal and the other as a substrate crystal. (1) Familiar orientation relationships, such as the Kurdjumov-Sachs (K-S) relationship, were found between deposit and substrate crystals when low-index substrate planes were used. On the other hand, several new orientation relationships were found to exist on some higher-index substrate planes. (2) Iron deposited on copper as thin film layers with domain structure. However, copper deposited on iron as many fine islands.3. Iron was deposited on an [001]-oriented needle-like specimen of copper. The semi-spherical tip of the specimen was examined on a field-ion microscope (FIM). It has been found that four separate regions of iron film exist around the [001] pole and each region shows the K-S relationship to the copper substrate.4. In the light of the experimental results, the following three factors have been identified critical in determining epitaxial relationships on given substrate orientations: (1) the Bain correspondence between the two crystals, (2) the good matching of the two crystals at the interface, and (3) minimization of misfit strain energy.5. Using the infinitesimal-deformation approach, the crystallography of martensites or precipitates in a bulk material has also been discussed theoretically.

在该项目的两年期间，已经取得了以下成就1。使用此补助金的设备预算构建了一种具有更好真空的新沉积设备2。选择铜和铁，一种作为沉积物晶体，另一个作为底物晶体。（1）当使用低索引底物平面时，发现了熟悉的取向关系，例如kurdjumov-sachs（K-S）关系。另一方面，发现在一些高索引底物平面上发现了几种新的定向关系。（2）铁作为具有域结构的薄膜层沉积在铜上。但是，铜沉积在铁上和许多细岛上。3。铁沉积在[001]面向铜的针状标本上。在野外离子显微镜（FIM）上检查了标本的半球尖。已经发现，在[001]极周围存在四个独立的铁膜区域，每个区域都显示了K-S与铜底物的关系。4。鉴于实验结果，在确定给定底物方向上的外延关系时已经确定了以下三个因素：（1）两种晶体之间的贝恩对应关系，（2）界面上两个晶体的良好匹配，（3）（3）不合适的应变能的最小化。5。从理论上讨论了无限构造方法，在散装材料中的晶体材料或沉淀物的晶体学也进行了讨论。
