    • 塊狀金屬玻璃 (BMGs) 在室溫下通常經過非常有限的塑性變形即斷裂，因此限制了其在工程材料上的應用，由於金屬玻璃的變形是由剪切帶及剪切滑移所造成，因此促進剪切帶的生成與傳播來使其塑性變形更為重要。
    在本研究中，於鋯基金屬玻璃的張應力面進行不同方式的表面改質來增加其四點彎曲延展性及疲勞性質。於彎曲延展性實驗中，其表面改質包括人工刮痕、金屬玻璃鍍層及飛秒雷射處理。預先存在的剪切帶由刮痕產生於金屬玻璃表面因而造成剪切軟化，在負載時應力集中於刮痕因而造成多重剪切帶生成與滑移，因此相較於剛拋光的試片，有刮痕的試片呈現至少1.5倍高的塑性應變。鍍有金屬玻璃薄膜的試片也顯著地展現增強的彎曲塑性(增加>2倍)，500 奈米厚的金屬玻璃塗層具有很高的韌性，能夠促進均勻分佈及高密度剪切帶的形成，因此大量剪切帶的分支可以防止局部剪切滑移進而得到增加的塑性應變。此外，經受飛秒雷射處理後的試片顯示出增加的塑性應變(增加>1.8倍)，可能是由於應力分佈集中於凹槽和飛秒雷射產生的雷射誘導週期性表面結構中。
    經彎曲試驗後，我們也研究了金屬玻璃試片剪切帶的間距與滑移，結果顯示，高密度剪切帶與大型剪切帶偏移量形成於表面改質金屬玻璃試片中可以防止局部剪切帶並承受較大的彎曲塑性變形。結果顯示，此研究中不同的表面改質方式成為有潛力的方法來增強大尺寸的塊狀金屬玻璃之彎曲延展性。
    另一方面，我們於金屬玻璃基材度上一層200奈米厚的金屬玻璃薄膜來增加其疲勞性質，相較於無鍍膜的塊狀金屬玻璃，鍍膜試片的疲勞壽命增加至少25倍，並且疲勞限也上升33%，表面光滑、良好附著力及高韌性之金屬玻璃薄膜被認為是增強金屬玻璃基材之疲勞性質重要的角色。

    Bulk metallic glasses (BMGs) are normally fractured with very limited plastic strain at room temperature, severely restricting their application as engineering materials. Since deformation in BMGs is accommodated by shear bands and shear-offsets, it is important to promote homogenous formation and propagation of shear bands in order to obtain plastic strains.
    In this study, various surface modifications were performed on the tensile surface of Zr-based BMG substrates to enhance their four-point bending ductility and fatigue properties. The surface modifications for ductility enhancement include artificial scratch, thin film metallic glass (TFMG) coating as well as femtosecond laser patterning. For the artificial scratch, the pre-existing shear bands are generated and they lead to shear-softening. The stress is concentrated in the scratches upon loading, which causes the multiple shear band formations and offsets. As a result, the scratched samples show at least 1.5 times higher plastic strain than that of as-polished samples. The TFMG coated samples also exhibit significantly enhanced bending plasticity (>2 times improved). A 500 nm-thick TFMG coating with high toughness is capable of promoting the formation of a high density of homogeneously distributed shear bands. Thus, abundant of shear band branches can prevent shear band localization so as to obtain increased plastic strain. In addition, the samples after being subjected to the femtosecond laser patterning show an increased plasticity (>1.8 times improved) which might be attributed to stress redistribution in the grooves and the laser-induced periodic surface structure produced by femtosecond laser.
    The shear band spacing and offsets on BMG samples are also examined after bending test. It is found that a high density of shear bands with large shear band offset formed in surface-modified BMG samples can prevent localized shear banding and accommodate large plastic deformation under bending. The results demonstrate that the various surface modifications in this study become promising methods for bending ductility enhancement of large-scale BMG.
    On the other hand, a 200 nm-thick TFMG was deposited on the BMG substrate to improve the four-point bending fatigue properties. The fatigue life of a coated BMG substrate is significantly improved by at least 25 times and the fatigue limit is increased by 33% compare with the bare one. The smooth surface, good adhesion and high toughness of film are found to play an important role in superior fatigue properties.
