Speech Title: Microstructure, Tensile Properties and Fracture Behaviour of HPDC Magnesium Alloy AZ91

Abstract: Understanding of tensile and fracture behaviours of die cast magnesium alloys is of importance for proper design of various emerging automotive applications. In the present study, magnesium alloy AZ91 was high pressure die cast into rectangular coupons with section thicknesses of 2, 6 and 10 mm. The effect of section thicknesses on strain-hardening and fracture behaviours of the die cast AZ91 was investigated.  The results of tensile testing indicate that the ultimate tensile strength (UTS), yield strength (YS), elongation (ef), modulus, toughnrss and resilience decrease to 129.17, 110.59 MPa, 0.37%, 25.9 GPa, 0.89 MJ/m3, and 236.10 kJ/m3 from 245.54, 169.26 MPa, 4.07%, 37.8 GPa, 8.34 MJ/m3, and 378.95 kJ/m3 with increasing section thicknesses of die cast AZ91 to 10 mm from 2 mm, respectively.  The analysis of true stress vs. strain curves shows that the straining hardening rates during the plastic deformation of the alloy increase to 5500 MPa from 4600 MPa with decreasing the section thickness to 2 mm from 10 mm, respectively.  The microstructure analyses by the optical microscopy (OM) and scanning electron microscopy (SEM) reveal that the high tensile properties should be attributed the low porosity level, fine dendrite structure, high eutectic content, and thick skin.  The observation via SEM fractography illustrates that the fracture behaviour of die cast AZ91 is influenced by section thicknesses. As the section thickness increases, the fracture of AZ91 tends to transit from ductile to brittle mode due to arising porosity content and coarsening microstructure.

Prof. Sarawut Rimdusit

Chulalongkorn University, Bangkok, Thailand

Biography: Dr. Sarawut Rimdusit is a full professor of the Department of Chemical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok, Thailand. He received his master and doctoral degrees from the Department of Macromolecular Science and Engineering, Case Western Reserve University, Cleveland, Ohio, USA in 1997 and 2000, respectively. He worked as a post-doctoral fellow under a Hitachi research fellowship in 2005 and 2008 at Toyohashi University and Technology and Monbusho research fellowship in 2003 at the Japan Aerospace Exploration Agency (JAXA, formerly ISAS). His research is concentrated on multicomponent polymeric systems based on polybenzoxazines and some network forming polymers. His recent research focuses on the use of polybenzoxazine alloys as functional materials including shape memory materials and thermoreversible light scattering polymers. He has published 1 book on polybenzoxazine alloys and composites (Springer), 10 book chapters in English, 4 book chapters in Japanese and more than 70 international papers related to the alloys and composites of polybenzoxazines.

Speech Title: Functional Materials Based on Polybenzoxazine Alloys

Abstract: An ability of benzoxazine resin to alloy with various kinds of resins or polymers is considered one of its unique characteristics. In this research, an ability of benzoxazine resin to alloy with epoxy and urethane resins to form polymers with shape memory behaviors as well as to give materials with thermo-reversible light scattering (TRLS) characteristics is described. The dual function of benzoxazine resin to act as curing agent of epoxy resin and as a stable or rigid network segment for shape memory epoxy significantly simplifies a formulation of shape memory epoxy systems with enhanced recovery stress. Recovery stress enhancement and light activating capability can also be obtained with an incorporaiton of carbon nanotube in the alloys. Furthermore, the alloys of benzoxazine resin with suitable urethane elastomers render relatively broad glass transition temperature with multiple-shape memory effects. These classes of benzoxazine-urethane alloys also show interesting thermo-optical characteristics namely thermo-reversible light scattering behaviors that the materials can be switched from opaque state (off-state) to transparent state (on-state) by varying temperature. TRLS films have potential applications in thermal sensors, optical devices, recording media etc.
