Research
Research areas and external collaborators
Research Areas
Within the broad field of materials engineering, Dr. Cheng Yan and his research team have undertaken the research in the following areas:
- Deformation and fracture of nanocrystalline and amorphous alloys
- Mechanical behavior of thin films in micro- and nano-devices
- Microelectronic and photonic packaging
- Characterization of Light Alloys
- Polymer nanocomposites
- Mechanical behaviour of photonic crystal optical fibres
- Synthesis of novel materials via mechanical milling
- Effect of constraint on fracture of materials
Deformation and fracture of nanocrystalline and amorphous alloys
Comparison of yield strength in various Mg alloys
Interest in development of advanced materials has been excited by microstructural refinement and modification of structure through the formation of nonequilibrium phases (amorphous, quasicrystalline and nanocrystalline), due to their superior mechanical, magnetic and electronic and transport properties which can not be obtained from conventional crystalline metals. The developments emphasize the need to explore, at a fundamental level, the progress associated with deformation and fracture of nanocrystalline and amorphous metals. In this project, deformation and failure of nanocrystalline and amorphous alloys will be investigated via mechanical testing, numerical modelling and advanced microanalysis.
Mechanical behaviour of thin films in micro- and nano-devices
FE simulation of nanoindentation of multilayer thin film
Many of the components used in modern products are becoming smaller and smaller. Standard integrated circuit (IC) and other emerging micromachining techniques have enabled the creation of a new generation of microsystems, such as MEMS and NEMS systems. However, poor system reliability, due to the lack of fundamental understanding of materials behaviour at micro- or nano-scale, is a well-known potential technical barrier to the advance of these technologies. This project aims to investigate the deformation, failure, wear and adhesion mechanisms of metallic, ceramic (e.g. silicon) or polymer layers at micro- and nano-scales.
Microelectronic and photonic packaging
Finite element analysis of a ball grid array package
The project is aimed at conducting experimental and theoretical investigations to establish theories and techniques for characterising thermal-mechanical performance of microelectronic and photonic packages and other microsystems. The effects of materials mismatch, constraint and defects on failure mechanisms will be investigated to build up sophisticated life prediction models. The outcomes can be used to create a knowledge base of materials properties and failure mechanisms for design, reliability evaluation and life prediction in micro-devices.
Characterization of Light Alloys
Microstructure of AZ91 Mg alloy
Light alloys (Al, Mg and Ti), because of their superior stiffness-to-weight ratio, have been increasingly used in aerospace and aircraft structures as well as for structural components in ultra-lightweight communication systems. Australia is poised to because a world leader in light metals and the supply of relevant products into the global marketplace. However, lower strength and poor resistance to corrosion; wear and creep have slowed their development and industrial use. In this work, mechanical properties of light alloys will be characterized to understand the structure-property relationships.
Polymer nanocomposites
Carbon nanotubes in polymer matrix
Polymeric materials have been widely used in almost every sector of industry. It is known that substantial enhancement in physical and mechanical properties of polymeric materials can be achieved by blending them with micro- or nano-sized particles to form nanocomposites. For example, a commonly accepted view on the role of rubbery particles is that the rubber inclusions alter the stress state in the materials around the particles and induce extensive plastic deformation in the matrix, thereby increasing the ductility and fracture toughness. Recently, various fillers and carbon nanotubes have been added into polymers to improve their electrical conductivity and mechanical properties. The objective of this project is to fabricate polymer nanocomposites using nanosized particles and carbon nanotubes. The mechanical and electrical properties will be evaluated and simulated. The attention will be also focused on the structure-property relationship in these novel nanocomposites.
Mechanical behaviour of photonic crystal optical fibres
Fracture surface of silica photonic crystal optical fibre
Recently, photonic crystal fibres (or more specifically, holey fibres and air-material fibres) are of interest since they offer a simple alternative to controlling the index profile of optical waveguides other than using expensive dopants. Although many types of optical fibres and cables have been developed to meet the needs of communication service providers for long-term performance and reliable operation, the brittle nature, mechanical damage and failure of silica fibres, remain to be the key materials issues. In this project, the mechanical behavior of photonic crystal fibers and its dependence on microstructure and environmental condition will be investigated.
Synthesis of novel materials via mechanical milling
Schematic of ball milling
It has been demonstrated that many materials can be produced via mechanical milling in conjunction with other processing routines, such as nanocrystalline alloys, nanomaterials and novels polymers. Recently, Mg-based hydrogen storage materials have been successfully produced via reactive milling. In this project, mechanical milling will be used to produce amorphous alloys, nanocomposites or novel polymers.
Effect of constraint on fracture of materials
Effect of notch on fracture of Mg alloy
It has been demonstrated that geometrical constraint plays a critical role in failure of various engineering materials. One of the central objectives of fracture mechanics is to establish a relationship between constraint and failure behaviour of materials so that the failure of a given engineering structure can be predicted from laboratory testing. Extensive investigation has been conducted by Dr. Yan to gain a better understanding of the effects of constraint on failure of metals, polymers, composites, welded and adhesive joints, thin films, nanostructured materials and microsystems.
