1、前言为了使飞机在性能上达到99.99％以上的安全性并且最大限度的达到轻量化的要求,对所使用的原材料进行广泛的研究和对研究的材料进行积累是必要的。日本近三十年来在飞机制造领域中,材料工业几乎没有进行开发,因此和一些外国相比大大落后了。然而在这个领域中,五十岚和北原两位博士在发明超硬铝(ESD)方面却有着光荣的历史和传统。如果今后日本也以开发高强度材料作为继续研究的目标,那么有可能走
1, Foreword In order to make the aircraft more than 99.99% in safety and meet the requirements of light weight to the maximum, it is necessary to conduct extensive research on the used raw materials and to accumulate the studied materials. In the past 30 years in the field of aircraft manufacturing in Japan, the material industry has hardly been developed and has lagged far behind some foreign countries. However, in this area, the two Ph.D. Arashi and Kitahara Ph.Ds have a glorious history and tradition in inventing super-hard aluminum (ESD). If Japan in the future also to develop high-strength materials as the goal of continuing research, then it is possible to go
