Drillability of titanium alloy 6246
(Auckland University of Technology, 2018)Titanium alloys are relatively new materials that have been used extensively, especially in aerospace applications. The main properties are: a high strength to weight ratio (three times that of steel), an ability to maintain ... -
The Effect of Scan Speed on Lack of Fusion Formation During Electron Beam Melting of Ti-6Al-4V Alloy and Crack Growth Behaviour of the Alloy Under Impact and Fatigue Loading
(Auckland University of Technology, 2019)Electron beam melting (EBM) is a powder-bed fusion additive manufacturing process suitable for fabricating metallic parts with a high degree of shape complexity, opening EBM’s application potential with the Ti-6Al-4V alloy ... -
Formability of Magnesium AZ80
(Auckland University of Technology, 2016)Economical and fuel-efficient vehicles are a current topic of interest worldwide, due to increasing fuel costs and environmental concerns. The most strident demand from various auto-sector stakeholders is to reduce emissions ... -
Machinability and microstructural studies on phase transformations in Austempered Ductile Iron
(Auckland University of Technology, 2012)Austempered Ductile Iron (ADI) is a type of nodular, ductile cast iron subjected to heat treatments - austenitising and austempering. The heat treatment gives ADI its unique ausferrite microstructure through which ADI gets ... -
Robust Livestock Detection and Counting Using an Unmanned Aerial Vehicle (UAV)
(Auckland University of Technology, 2022)Fast pasture growth makes pastoral farming low-cost, sustainable and efficient for New Zealand. However, in recent years, sheep farming has declined due to the extra labor needed in handling these farms. One of the main ... -
Understanding Material Flow at the Interface of Friction Stir Lap Welding (FSLW) of Al-to-Cu Plates
(Auckland University of Technology, 2019)Aluminium to copper bimetal parts have seen wide use in electrical componentry. A continuous interface between the two alloys is necessary in order to have unhampered electron path. Friction stir welding, especially in a ...
