Project 1: Laser welding additive manufacturing of materials and structures for marine and offshore applications

Supervisor: Associate Professor Zhou Kun

Description: 

Laser welding presents a particular suitability for joining of metals and their alloys due to high precision, high-energy concentration, small deformation, rapid processing potentials and easy setup for automation. Laser welding-based additive manufacturing has been used to assemble large-scale structures from their components and remanufacture existing parts in automobile, marine engineering, aerospace and biomedical applications. This project focuses on methodologies of laser welding additive manufacturing of metallic materials and structures for marine and offshore applications. The effect of processing parameters on the microstructural features, mechanical and corrosion properties of additively welded joints and printed structures will be investigated. The heat-affected zones of the welded joints will be analyzed to understand the weld pool evolution. The corrosion resistance and mechanical performance (hardness, tensile, fatigue, impact and fracture toughness properties) of the additively welded metals will be compared with the ASTM standard. Numerical modelling will be conducted to understand the temperature distribution and residual stresses during laser welding additive manufacturing for guiding process optimization. A damage mechanics approach-based model will also be established to predict the mechanical behavior and fatigue lifetime of additively welded structures for quality control. This research will provide valuable knowledge on the development of laser welding additive manufacturing in the applications of marine and offshore.


Project 2: Non-destructive characterization of material microstructure from additive manufacturing

Supervisor: Assistant Professor Fan Zheng David
Co-supervisor: Associate Professor Yeong Wai Yee

Description: 

The mechanical performance of structural elements has long been connected with the microstructural features of materials constituting them. Microstructural variations have often been thought to be the reason behind performance variabilities in otherwise identical components. However, controlling the microstructural signature of additive manufacturing is a challenging task. While electromagnetic NDE techniques such as Electron backscatter diffraction (EBSD) and X-ray tomography could potentially yield a very fine insight into the volumetric internal structure of components, they are often expensive, time consuming and not easily implementable on practical samples or environments. In this PhD work, ultrasonic methods, which is portable and cost-effective, will be explored to characterize material microstructure, including texture mapping and grain size distribution.​

NEWRI Graduate Scholarship

Project: 3D printing of multi-porosity ceramic membranes for process intensification

Supervisor: Associate Professor Yeong Wai Yee
Co-supervisor: Assistant Professor Chong Tzyy Haur

Description:
Ceramic membranes are widely used in liquid filtration and waste treatment. Conventional ceramic membranes are homogeneous in microstructure and multiple membrane systems with different porosity and pore size have to be used in a typical process flow. This is usually associated with increased cost and process inefficiency. 

3D printing is new manufacturing technology that allows freeform custom design and low cost fabrication at low production volume. With recent development in 3D printable ceramic materials, there is an opportunity to apply 3D printing to the design and fabrication of new ceramic membranes. Therefore, we propose to 3D print a multi-porosity ceramic membrane for process intensification. In this research, design, simulation, fabrication and characterization of the new ceramic membranes will be carried out.
