The morphological and structural changes of two different dual-phase tungsten alloy (either 3% or 5% of an added mixture of Fe and Ni) are investigated after deuterium plasma irradiation. Heat flux factor of deuterium plasma pulses is comparable to transient events in ITER. This study compares the changes in tungsten alloy materials between two different regimes with a different number of plasma pulses. Fe and Ni as a binder play an essential role in absorbing plasma shocks to decrease the morphological and structural changes. These results are compared to changes of pure single and double forged tungsten irradiated in similar conditions.

脉冲氘等离子体辐照对双相钨合金的影响

在氘等离子体照射后,研究了两种不同的双相钨合金(Fe和Ni的添加混合物的3%或5%)的形态和结构变化。氘等离子体脉冲的热通量因子与ITER中的瞬态事件相当。这项研究比较了两种不同状态下具有不同数量等离子脉冲的钨合金材料的变化。铁和镍作为粘合剂在吸收等离子体冲击以减少形态和结构变化方面起着至关重要的作用。将这些结果与在类似条件下辐照的纯单锻造和双锻造钨的变化进行比较。
