一、前言目前遥感探测技术迅速发展,空防体系日趋完善,飞航式导弹的突防受到了愈耒愈严重的威胁。为了提高导弹的突防能力,要求导弹在更广泛的空间活动,具有更高的速度,更大的机动性和更隐蔽的飞行特性。因此导弹的设计师自然对材料技术提出更高的要求。新型导弹的发展必然要为材料 I. Introduction At present, the rapid development of remote sensing detection technology and the improvement of air defense systems are increasingly threatening the penetration of airborne missiles. In order to improve the penetration capability of missiles, missiles are required to move in a wider space with higher speed, greater maneuverability and more subtle flight characteristics. Therefore, the missile designer naturally put forward higher requirements for material technology. The development of new missiles must be made of materials
