本文研究了β-W所含氧的性质。研究表明,非自燃β-W所含的氧可分为两部分:可逆化学吸附的氧和可能与β-W组成填隙式固溶体的填隙氧。β-W是金属W的一种亚稳相,而填隙氧的存在使β-W的亚稳晶格较为稳定。
The nature of the oxygen contained in β-W was investigated withDSC, X-ray analysis on quenched samples and Auger spectroscope. It was shownthat the oxygen contained in nonpyrophoric β-W consists of the reversiblychemisorbed oxygen and the interstitial oxygen which could form an interstitialsolid solution with β-W. It seems better to consider β-W to be a metaphase of Wwith theinterstitial oxygen as stabilizer.
