The present work has been performed to develop intelligent materials which have strong resistance to both beam impact (or shock-wave) and radiation damage. They are required for the beam target of an intense accelerator and space applications. Main results are as follows : (1)For the tungsten target, radiation-resistant, ultra-fine grained tungsten materials was successfully developed with a mechanical alloying method, dispersing TiC into tungsten. (2)The GBE (grain boundary engineering) controlled stainless steels were developed for the purpose to overcome an inter-granular corrosion which occurs in a heat affected zone of a weld material. (3)As a coating technique for tungsten target, CrN film formation with the molten salt method has been attained to be several micro-meter thickness. (4)For liquid mercury target, synergistic effect of C and N plasma surface treatment to suppress pitting damage was prominent. High-speed camera clarified bubble behavior near mercury/glass window surfa … More ce and gave a clue of pitting problem. (5)To space application, we developed the tough AIN-TiN composite material and the intelligent material composed of niobium and aluminum that has an intelligence to stop propagation of micro-cracks created by debris attack. (7)Rapid cooling test of tantalum-clad tungsten plate fabricated with the HIP method for MW-class spallation target showed that the plate was not broken and will be endurable even in case of loss-of-coolant accident. (8)Positron lifetime measurement clarified no effect of GBE to defect formation, and did irradiation effects. (9)Post irradiation experiments for STIP-II samples which had been irradiated at the spallation target of the SINQ facility at Paul Scherrer Institut showed that the JPCA, stainless steel (SS) produced in Japan had elongation above 3 dpa, while the SS-316 irradiated at LANSCE lost elongation above 3 dpa. Future tasks are to collect more experimental data of damages, to progress a theoretical investigations and develop the simulation code system, and to develop essentially strong materials. Less

目前的工作已经进行了开发智能材料，这些材料对光束冲击（或冲击波）和辐射损伤具有强烈的抗性。它们是强度加速器和空间应用的光束目标所必需的。主要结果如下：（1）对于钨靶，使用机械合金方法成功地开发了耐辐射，超细的颗粒钨材料，将抽动分散到钨中。 （2）开发了GBE（晶界工程）受控的不锈钢，目的是克服颗粒间腐蚀，该腐蚀发生在焊接材料的热影响区域中。 （3）作为钨靶的涂料技术，用熔融盐法的CRN膜形成已连接为几个微米的厚度。 （4）对于液态汞靶标的，C和N血浆表面处理对抑制点损伤的协同作用是显着的。高速摄像头澄清了水星/玻璃窗窗口附近的气泡行为…更多的CE，并给出了解决问题的线索。 （5）到达太空应用，我们开发了坚硬的Ain-Tin复合材料和由Niobium和Aluminum组成的智能材料，该材料具有智能，可以停止碎片攻击产生的微裂缝的传播。 （7）用髋关节方法制造的坦塔塔勒式钨板的快速冷却测试用于MW级剥落靶标，表明该板没有破裂，即使在造成冷却剂事故的情况下，也可以持久。 （8）正电子寿命测量未阐明GBE对缺陷形成的影响，并产生了辐照效应。 （9）在Paul Scherrer Institut的SINQ设施的散布靶标辐射的STIP-II样品的辐照实验显示，日本生产的JPCA，不锈钢（SS）的伸长延伸于3 DPA以上，而SS-316则在Lansce失去的SS-316在Lansce Lost foss fosited Loss nofded eLongation Losse eLongation eLonongation eLonongation e那高于3 dpa。未来的任务是收集更多的损害实验数据，进行理论研究并开发仿真代码系统，并开发基本强大的材料。较少的
