非晶态金属的原子排列是无规密堆的,没有长程序,只是局域地保持一定的短程序。由于这种特殊的微观结构,块体非晶合金的机械物理性能都有极大的变化。Ti基非晶合金延续了块体非晶合金的以上优点,除了具有较高的抗拉强度、和高的抗腐蚀性能,此外,由于主合金元素Ti的低密度(

Abstract:
The effect of Sn substitution for Cu on the glass-forming ability was investigated in Ti41.5Zr2.5Hf5Cu42.5−xNi7.5Si1Snx (x = 0, 1, 3, 5, 7) alloys by using differential scanning calorimetry (DSC) and X-ray diffractometry. The alloy containing 5% Sn shows the highest glass-forming ability (GFA) among the Ti–Zr–Hf–Cu–Ni–Si–Sn system. Fully amorphous rod sample with diameters up to
