Research progress on damage behavior of tungsten-base materialsunder high heat load

摘要:

钨材料优异的理化性能使其成为面壁等离子体材料的备选材料之一。对纯钨和钨基材料高热负荷作用下的损伤行为进行了比较和分析,在此基础上,介绍了轧制态钨、再结晶态钨、W-La₂O₃、W-TiC、W-ZrC、W-V和W-Ta合金在不同热负荷条件下的损伤行为,讨论了损伤机理,并指出了尚需研究的若干关键问题。

Abstract:

Tungsten is one of the most important candidate materials in plasma surface materials, due to its excellent physical and chemical properties. On the basis of comparison and analysis of damage behavior of pure tungsten and tungsten-base materials under high heat load, such as rolled tungsten, recrystallization tungsten, W-La₂O₃、W-TiC、W-ZrC、W-V and W-Ta. Damage mechanism are discussed. Several key issues which need to be studied hereafter are put forward.
