1A Newly Developed Non-Destructive Tritium Measurement Technique and Its Application to V-4Cr-4Ti Alloy显示文摘A non-destructive and in-situ technique for the measurement of tritium in materials,namely β-ray-induced X-ray spectrometry (BIXS),has been developed recently.In the presentstudy a V-4Cr-4Ti alloy was pre-heated at 1000℃ for 2 h to form a recrystallization structurebefore the tritium absorption experiments were conducted.Firstly the hydrogen isotope gas wascharacterized by means of a quadrupole mass spectrometer (QMS) and a small-sized ionizationchamber.Then hydrogen isotope absorption tests of V-4Cr-4Ti alloy were performed at 400℃and the atomic concentration of hydrogen isotope in V-4Cr-4Ti alloy was estimated as 0.17%with a tritium content of approximately 2.5 ppm.Experimental results indicate that BIXS is aquite useful tool for quantitatively measuring the tritium content and tritium distribution in thesurface layers of vanadium alloys and no strong trapping effects of tritium exist in the pre-heatedV-4Cr-4Ti alloy.刘翔 陈学 H.HOMMA Y.HATANO M.MATSUYAMA 2006Plasma Science and Technology2006,8,6:0
