Metallic glasses are promising materials for engineering applications due to their high elastic limits and high hardness. One of the major drawbacks of metallic glasses is their brittle nature. One approach to improve their ductility is to utilize a metallic glass – crystalline nanocomposite. In this work, we investigated the mechanical properties of nanolayered CuTi metallic glass – nanocrystalline Ti thin films. The nanolayered structure has the potential to offer higher ductility, and CuTi-Ti is a biocompatible model system that has potential to be used as wear and corrosion resistant coatings for medical implants. We prepared thin films of CuTi-Ti with fully amorphous CuTi and nanocrystalline Ti layers. The multilayers show comparable hardness to that of single phase CuTi metallic glass coatings. Combination of high strength and ductility make nanolayered metallic glass – crystalline composites promising materials for wear resistance applications.

Metallic glasses are metallic alloys with disordered atomic structures and desirable mechanical properties such as high hardness, high elastic limits, and wear resistance. These properties make metallic glasses promising materials for wear-resistant, corrosion-resistant, and biocompatible coating applications. On the other hand, metallic glasses are brittle, which is a major disadvantage for their use in practice. This thesis study aimed to tackle this problem through the development of nanostructured metal...
Mechanical behavior of metallic glass / HCP nanolayered coatings
Özerinç, Sezer; Motallebzadeh, Amir (null; 2019-09-01)
Introduction/Purpose High hardness, large elastic limits and grain-boundary free structure of metallic glasses (MG) make them promising materials for wear resistant, corrosion resistant and biocompatible coatings [1]. However, the brittle nature of MGs in monolithic form is a major disadvantage. MG/crystalline nanolayered composites can overcome this problem by impeding the catastrophic propagation of shear bands [2]. Most studies so far on these nanocomposites have focused on MG/FCC crystalline structures ...
Optimization of metalization in crystalline silicon solar cells
Demircioğlu, Olgu; Turan, Raşit; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2012)
Production steps of crystalline silicon solar cells include several physical and chemical processes like etching, doping, annealing, nitride coating, metallization and firing of the metal contacts. Among these processes, the metallization plays a crucial role in the energy conversion performance of the cell. The quality of the metal layers used on the back and the front surface of the cell and the quality of the electrical contact they form with the underlying substrate have a detrimental effect on the amou...

In biomedical applications, the conventionally used metallic materials, including stainless steel, Co-based alloys and Ti alloys, often times exhibit unsatisfactory results such as stress shielding and metal ion releases. Secondary surgical operation(s) usually become inevitable to prevent long term exposure of body with the toxic implant contents. The metallic biomaterials are being revolutionized with the development of biodegradable materials including several metals, alloys, and metallic glasses. As suc...

Erdem, Mermer; Akdeniz, Mahmut Vedat; Mekhrabov, Amdulla O.; Department of Metallurgical and Materials Engineering (2013)
Copper based bulk metallic glasses (BMG’s) are one of the promising advanced materials due to their unique mechanical properties, high glass forming ability (GFA) and low cost. In this thesis, the aim is to synthesize Cu-Hf based BMG’s and to investigate the crystallization behavior. Moreover, the crystallization kinetics by means of activation energies, critical cooling rate, nanocrystallization and Avrami exponents have been studied. Cu70Hf30 and Cu50Hf50 binary alloys were produced via arc melting with s...
