Abstract

Abstract

An experimental system of high-temperature split Hopkinson pressure bar (SHPB) was developed, and the dynamic properties of one type of antihydrogen steel at temperatures from room temperature to 1 000 ℃ and at strain rates from 500 to 1 000 s1 were studied using this system. The experimental system and the heated specimen were assembled rapidly by using a pneumatic mounting system to minimize the development of temperature gradients in the specimen. The experimental results show that the contact time is shorter than 500 ms. The softening effect of the antihydrogen steel due to heating is large, and the temperature sensitivity decreases quickly with the specimen temperature increasing.
