利用自行研制的原位小冲片装置，研究了纯铌金属膜在氢气氛下的氢脆行为。通过一系列的原位小冲杆试验确定了镀钯纯铌的韧脆转变边界。与未涂钯的铌膜相比，测得的边界大大向氢含量较低的区域移动。这一结果为设计抗氢脆的铝基渗透膜提供了线索。(C)2007 Elsevier B.V.保留所有权利。
The hydrogen embrittlement of pure niobium metal membrane was investigated under a hydrogen atmosphere by using a newly developed in situ small punch apparatus. The boundary for the ductile-to-brittle transition of the palladium-coated pure niobium was determined from a series of the in situ small punch tests. The measured boundary was found to be shifted greatly to the lower hydrogen content region as compared to that of palladium non-coated mobium membrane. The present result will provide us a clue to the design of niobium-based permeable membrane against the hydrogen embrittlement. (C) 2007 Elsevier B.V. All rights reserved.
