    摘要:

    鈦具有高強(qiáng)度，低密度，耐腐蝕等特性，并在多個(gè)領(lǐng)域得到應(yīng)用。多年來，鈦的同素異構(gòu)體的晶體結(jié)構(gòu)和結(jié)構(gòu)轉(zhuǎn)變受到了學(xué)者的廣泛關(guān)注。除了密排六方結(jié)構(gòu)的平衡相（α-Ti），面心立方結(jié)構(gòu)的高溫相（β-Ti）和六方結(jié)構(gòu)的高壓相（ω-Ti）外，學(xué)者通過各種方法嘗試在極端條件下制備鈦的其他亞穩(wěn)相結(jié)構(gòu)。在過去的幾十年中，人們?cè)诔邏簵l件下發(fā)現(xiàn)了γ-Ti和δ-Ti，并通過高壓扭轉(zhuǎn)實(shí)驗(yàn)、激光沖擊實(shí)驗(yàn)和超薄薄膜實(shí)驗(yàn)等方法制備了在室溫條件下可以穩(wěn)定存在的ω-Ti和fcc-Ti。綜述了鈦的同素異構(gòu)體（不包括合金）的晶體結(jié)構(gòu)和結(jié)構(gòu)轉(zhuǎn)變類型，并介紹了不同結(jié)構(gòu)鈦的穩(wěn)定性以及結(jié)構(gòu)轉(zhuǎn)變機(jī)理。

    Abstract:

    High strength, low density, and excellent corrosion resistance are the main properties making titanium attractive in a variety of applications. The crystal structures and structural transformations of titanium allotropes, which are of tremendous scientific and technological interest, have attracted a great deal of attention for many years. In addition to hexagonal close packed α-Ti, high temperature phase β-Ti with body-centred cubic structure and ω-Ti with the hexagonal structure, researchers have tried to find other metastable structures which can be maintained under extreme conditions through various methods. During the past decades, the ultrahigh pressure structures γ-Ti and δ-Ti are observed, and the room temperature ω-Ti and fcc-Ti can be obtained by high pressure torsion, laser shock, ultra-thin films, etc. The research progress of crystal structures and structural transformations of titanium were introduced. The structural stability and mechanism of structural transformations on titanium were elaborated.
