Research Abstract

The material in a high energy intense proton beam field receives damage due to an intense thermal shock and radiation. A shock damage process and influence were investigated experimentally and the easing method was drawn. Moreover, the simulation code which evaluates a radiation trauma theoretically was developed. Furthermore, our grain boundary engineering method has succeeded the four times increase in corrosion resistivity of various austenite stainless steels. New tungsten material developed with a ultra-fine grain powder has four times higher toughness than that of commercial tungsten and does ductility even at a room temperature. The quantitative method using the stress luminescence material in a shock experiment was devised to improve a material dynamics study.
