127. ‘One layer at a time’: Unlocking Novel Materials and Structures for Neutron Radiation Environments through Additive Manufacturing

Jonathan Knott (University of Wollongong)

Oral

The fact that neutrons can penetrate deeply makes them an excellent tool for probing the inner
structures of materials, however this property also means that effective management of neutron
radiation is a central challenge in nuclear engineering, neutron beam science and in the
electronics industry. Neutrons also form a significant proportion of space radiation, and therefore
novel,...

112. The effects of Bi addition on the mechanical properties of eutectic Sn-Ag-Cu lead-free solder alloy

Oral

Sn-Ag-Cu (SAC) solders are gaining momentum as the choice of Pb free electrical interconnect materials because of the legislative restrictions on the use of hazardous materials in electronic devices. However, SAC has high melting temperatures around 217oC. The role of Bi substitution to lowering solder joint processing temperatures are widely considered because of the low-temperature Sn-Bi...

91. Austenite formation kinetics from multicomponent cementite-ferrite aggregates by in situ neutron powder diffraction

Dr Yuxiang Wu (Monash University)

Manufacturing & Engineering

Oral

The development of third generation advanced high strength steels (AHSS) as the next generation sheet steel grade is driven by the automotive industry. The key processing step is called ‘intercritical annealing’ at temperatures in the region of the ferrite and austenite two-phase field. The transformed austenite during intercritical annealing will be retained at a metastable state in the final...

86. Thermal and Mechanical Analyses of Dental Composites for Class II Cavity Restoration in a Molar Tooth: A Finite Element Study

Mr Jerrin Thadathil Varghese (School of Mechanical and Manufacturing Engineering,)

13/11/2020, 15:54

Manufacturing & Engineering

Oral

Flowable dental resin composites have substituted mercury-based amalgam as dental restorations over the past decade due to amalgam’s biological adverse effect. The flowable dental resin composites are more preferred due to their material properties, aesthetics, and minimal invasiveness. Therefore, the effect of thermal and mechanical stimuli on resin dental composites is an area of active...

35. Current high-pressure capabilities at ACNS and future plans

Helen Maynard-Casely (Australian Nuclear Science and Technology Organisation)

Manufacturing & Engineering

Oral

High-pressure (>1 Kbar) is a marvellous variable, which can reveal mechanical properties, structural transitions and exotic behaviours. This pairs very well with neutron scattering, where the highly penetrating nature of neutron beams is idea for accessing sample within complex sample environments. The Australian Centre for Neutron Scattering (ACNS) has developed a number of capabilities...
