项目摘要

We investigate the relationship between the optical properties to surface morphology and crystal orientations of JIS A1070- and JIS A5020-aluminum alloys, and Cu-3%Al alloys, and then compared the decorative property of Cu alloys having coarsened grains.The following results were obtained as follows.Concerning JIS A1070 aluminum alloys :(1) The etched surface of crystals are classified into two types : one (type A) is the crystal which has smooth surface and shows high regular reflectance ; the other one (type B) is the crystal which has jagged surface such as a wavy pattern.(2) Type A crystals have the (310) or (100) plane and all of type B have the (110) plane.(3) The longish direction of wavy jag is virtually parallel to the <100> direction of type B crystal.(4) Since type B crystals have a properly dispersed direction (<80 degree), the brilliancy of each type B crystal can be shown by a multiform reflection.Concerning to Cu-3%Al alloys :(5) Etched surface of crystals are classified … More into four types : one (type A) is the crystal which has smooth surface ; the second one (type B1) is the crystal having stripe pattern ; the third one (type B2) is the crystal which has jagged surface such as a wavy pattern ; and last one (type C) is the crystal having cuboid unevenness.(6) The stripe pattern of type B1 crystal is created as intersection of crystal plane and etched plane.From these results, it is important for a decorative alloy to have a properly dispersed direction of crystal plane having stripe patterns with a view to showing a multiform reflection. Accordingly, the alloy plates composed of random oriented crystals prepared by proper cold working and heat treatment are found to be suitable for interior materials. Furthermore, the control of etched surface by etchant will be able to create the multiform morphology of crystal surface showing complex reflection. A proper combination of these processes can produce a good decorative material. Especially, Cu-Al and Cu-Zn (Marumo Brass 【〇!R】) alloys can be expected as new materials for crafts or interior products embodying western life style. Less

本文研究了JIS A1070铝合金、JIS A5020铝合金和Cu-3%Al合金的光学性能与表面形貌和晶体取向的关系，并比较了晶粒粗化的Cu合金的装饰性，得到如下结果：（1）JIS A1070铝合金的晶体腐蚀表面分为两类：一种（类型A）是具有光滑表面并显示高规则反射率的晶体;另一种（类型B）是具有锯齿状表面如波浪图案的晶体。(2)A型晶体具有（310）或（100）面，而所有B型晶体都具有（110）面。(3)波形锯齿的长边方向与B型晶体的方向基本平行。<100>(4)由于B型晶体具有适当的分散方向（<80 °），因此每种B型晶体的非晶性可以通过多种形式的反射来显示。 ...更多信息分为四种类型：一种（类型A）是具有光滑表面的晶体;第二种（类型B1）是具有条纹图案的晶体;第三种（类型B2）是具有锯齿状表面如波浪图案的晶体;最后一种（类型C）是具有长方体不平坦性的晶体。(6)B1型晶体的条纹图案是由晶面和蚀刻面的交点产生的，因此，为了显示出多种反射，装饰合金中具有条纹图案的晶面的适当分散方向是重要的。因此，通过适当的冷加工和热处理制备的由随机取向晶体组成的合金板被认为是适合于内部材料的。此外，通过蚀刻剂对蚀刻表面的控制，将能够产生具有复杂反射的多种形式的晶体表面形貌。这些工艺的适当组合可以生产出良好的装饰材料。特别是Cu-Al和Cu-Zn（Marumo Brass [Netherland! R]）合金有望成为体现西方生活方式的工艺品或室内装饰品的新材料。少
