在ITER设计中，选择CuCrZr作为第一壁和分流器部件的散热材料。本工作的目的是利用放置在590mev质子加速器中的原位试验机，检查CuCrZr合金在辐照同时循环变形时的材料疲劳性能。在100℃、应变控制、总应变范围为0.8%的条件下，进行了3次疲劳试验。梁内试件寿命最长。辐照后的试样寿命最短。梁内试件所测得的总塑性应变大于静态辐照或未辐照试件所测得的塑性应变。
In the ITER design, CuCrZr has been selected as the heat sink material for components of the first wall and the divertor. The objective of this work is to check the material fatigue performance when the CuCrZr alloy is cyclically deformed concurrently with irradiation, using an in situ testing machine placed in a 590 MeV proton accelerator. Three fatigue experiments have been conducted at 100 °C, under strain control, at a total strain range of 0.8%. The in-beam specimen reached the longest life. The post-irradiation tested specimen had the shortest life. The total plastic strain measured in the in-beam specimen was larger than the plastic strain measured in the statically irradiated specimen or in the unirradiated specimen.
