| 摘 要： | 采用铜模铸造法制备了不同直径的Ti40Cu34+xNi16-xZr10(x=0,2,4,5,6)系列合金,并利用X射线衍射(XRD)、扫描电镜(SEM)、差氏扫描量热仪(DSC)研究了合金的相结构、显微组织、热稳定性.结果表明:只有Ti40Cu39Ni11Zr10合金成分可制备出2 mm的全非晶结构,增加制备尺寸到3 mm、4 mm后,有TiCu晶体相析出;玻璃转变温度Tg、晶化温度Tx分别为665 K和712 K,过冷液相区ΔTx为47K.压缩实验表明:Ti40Cu39Ni11Zr10块体非晶合金具有高达1 931 MPa的屈服强度,并伴有0.3%左右微量压缩变形量,塑性变形以锯齿形式出现;Ti40Cu34Ni16Zr10合金具有1.3%的压缩变形量,TiCu相的析出提高了该合金压缩变形量.

| Abstract: | Ti-based bulk amorphous alloys with different diameters from 2mm to 4mm were formed in Ti40Cu34+xNi16-xZr10(x=0,2,4,5,6) system by copper mould casting.Their phase structure,microstructure and thermal stability were investigated by X-ray diffraction(XRD),scanning electron microscopy(SEM) and differential scanning calorimetry(DSC).The results show that 2mm in diameter for glass formation is obtained only for the Ti40Cu39 Ni11Zr10 alloy.The TiCu phase was distributed in amorphous matrix for increasing size to... |
