METASTABLE CHARACTERISTICS OF β-W

The nature of the oxygen contained in β-W was investigated with DSC,X-ray analysis onquenched samples and Auger spectroscope.It was shown that the oxygen contained innonpyrophoric β-W consists of the reversibly chemisorbed oxygen and the interstitial oxygenwhich could form an interstitial solid solution with β-W.It seems better to consider β-W tobe a metastable phase of tungsten with the interstitial oxygen as stabilizer.
