项目摘要

The containerless processing is preceived as the new process that the able to process the sample under noncontact, without requiring the difference, container from usual melting process. I think the thing that leaves expectation that the above process is able to samples it extremly easily, under the gravit, in other words, microgravity environment which become unweight environment, although I require enormous energy, to cancel the weight of the substance, in the case that I carry out an above new process on the ground especially. Therfore, as for this process the expectation is had to the presentation of the new reseach subject that the apparatus development becomes original case, of couse, as module for the international universe station alpha installation that the operation start is planned in 2003 A.D.However, the present condition is becoming the untrodden reserch range with the interior and exterior and only the exterior and only the experent enforcemeht example for high purity ma … More terials generation does not pass to be reported. Futhermore, the establishment of the base technology including such apparatus development that materials this process is having a big problem even in the stable levitation hold of the levitation sample of course. The application person did electromagnetic force the microgravity experiment that used the parabolic flight of the airplane by using various metals and alloys sample as the hold medium of the levitation sample, into this application research enforcement period. Mastering success in the stable hold of realization and, molten sample of levitation that used a low fusion point sample and suceed in the complete stable nonexistaent big result as all with the interior and exterior. Also, I mastered success to the precise temperature measuring of the undercooling coagulation process of that the application person used the semiconductor photodiode that established independently and succeed in the containerless solidification experiment of a Nd-Fe allys sample. Furthermore, the result that becomes evident to, the generation of the metastable phase that has the new structure and physical properties that are not obtained on the ground bt the large undercooling effect that is expected removal and microgravity environment of the core generation site by an application person original view point, in other words, containerless process was shown.

无容器处理是一种新的处理方法，它能在不接触的条件下处理样品，而不需要与通常的熔融过程不同的容器。我认为，在重力下，也就是说，在变成失重环境的微重力环境下，尽管我需要巨大的能量来抵消物质的重量，但我期望上述过程能够非常容易地对其进行采样，特别是在地面上进行上述新过程的情况下。因此，对于这一过程，期望出现新的研究主题，即设备开发成为原始情况，当然，作为计划于2003年开始运行的国际宇宙站α装置的模块。目前的状况正在成为一个既有内部又有外部、只有外部又只有经验执行的未涉足的研究领域高纯度MA的实施例 ...更多信息材料生成未通过报告。此外，包括材料这种工艺的设备开发在内的基础技术的建立当然即使在悬浮样品的稳定悬浮保持中也有很大的问题。应用人以各种金属和合金样品作为悬浮样品的保持介质，进行了利用飞机抛物线飞行的电磁力微重力实验，进入本应用研究实施期。成功掌握了低熔点样品的悬浮稳定性，并成功实现了悬浮熔融样品的稳定性，取得了内外均不存在的大成果。并在Nd-Fe合金样品的无容器凝固实验中，应用自行研制的半导体光电二极管对过冷凝固过程的精确温度测量取得了成功。此外，结果变得明显，具有新的结构和物理性质的亚稳相的产生，这是在地面上没有得到的，通过应用人的原始观点，换句话说，无容器的过程，预期的大的过冷效应和堆芯产生地点的微重力环境。少
