    摘要:

    使用真空電弧爐熔煉出TiZrHf中熵合金和純Ti,利用冷軋及退火得到再結(jié)晶后的等軸晶粒,并采用 X射線衍射方法研究其相組成；使用掃描電鏡和EBSD對TiZrHf合金和純Ti組織進(jìn)行表征并進(jìn)行滑移跡線分析。結(jié)果表明: TiZrHf合金與純Ti都為單相HCP結(jié)構(gòu)且軸比接近,經(jīng)再結(jié)晶后織構(gòu)類型都為基面織構(gòu)。在室溫下沿RD拉伸變形10%時(shí),TiZrHf合金的錐面滑移開動比例為26%,接近純Ti中錐面滑移晶粒占比的兩倍,且生成{10-12}拉伸孿晶的數(shù)量明顯多于純Ti。

    Abstract:

    : TiZrHf medium entropy alloy and pure Ti were prepared in vacuum arc furnace. The equiaxed grains were obtained by cold rolling and annealing, and their phase composition was studied by X-ray diffraction. Scanning electron microscope and Electron back scattered diffraction was performed to study the microstructure and in-grain slip activities of TiZrHf alloy and pure Ti. The results show that both TiZrHf alloy and pure Ti are single-phase HCP structure with approximately the same axial ratio, and their texture are basal texture after recrystallization. The pyramidal slip of TiZrHf alloy occupy a high fraction of～26% at 10% tensile strain along RD, which is twice the proportion of pyramidal slip in pure Ti, and the number of {10-12} tensile twins is significantly more than that of pure Ti.
