Additive manufacturing of Ti-6Al-4V with added boron: Microstructure and hardness modification
(Trans Tech Publications, 2018)Titanium alloy composites with titanium boride (TiB) discontinuous reinforcement have shown improved performance in terms of strength, stiffness, and hardness. Producing this composite through selective laser melting (SLM) ... -
The effect of heat treatments on microstructure and mechanical properties of as-extruded Ti-6Al-4V alloy rod from blended elemental powders
(Trans Tech Publications, 2018)In this study, Ti-6Al-4V bars were first prepared by extrusion of powder compacts from blended powder mixtures in the beta phase region, then the as-extruded bars were heat-treated following four different conditions: beta ... -
On microstructural evolution and mechanical properties of Ti-5Al-5V-5Mo-3Cr alloy synthesised from elemental powder mixtures
(Elsevier, 2018)In this paper, we explored to prepare a multi-compositional titanium alloy, Ti-5Al-5V-5Mo-3Cr (Ti-5553), by powder compact extrusion from elemental powder mixtures, and investigate the microstructure variation during the ... -
Effect of minor titanium addition on copper/diamond composites prepared by hot forging
(Springer Verlag, 2018)Copper/diamond composites have great potential to lead the next generation of advanced heat sink materials for use in high-power electronic devices and high-density integrated circuits because of their potential excellent ... -
Producing High-Quality Titanium Alloy by a Cost-Effective Route Combining Fast Heating and Hot Processing
(Springer, 2018)Powder metallurgy is a very attractive method for producing titanium alloys, which can be near-net-shape formed and have freedom in composition selection. However, applications are still limited due to product affordability. ... -
Evaluation of reactive induction sintering as a manufacturing route for blended elemental Ti-5Al-2.5Fe alloy
(Elsevier, 2018)This work focuses on gaining a better understanding of the feasibility of using reactive induction sintering to obtain the alloy Ti-5Al-2.5Fe using Ti, Al and Fe powders (i.e. via a blended elemental approach). For this, ... -
Effect of microwave sintering parameters on the physical and mechanical properties of pure Ti and blended elemental Ti alloys
(Trans Tech Publications, 2018)Microwave sintering (MWS) was used to consolidate hydride de-hydride Ti powder and blended elemental Ti6Al4V, Ti5Fe and Ti5Al5Mo5V3Cr (Ti5553) powder mixtures. The amount of powders used to prepare the powder compacts was ... -
Joint effect of steel addition and press-and-sinter on the properties of low-cost PM Ti Alloys
(Trans Tech Publications, 2018)Cheap alloying elements and creative processing techniques are a way forward to open up more industrial opportunities for Ti in sectors where it is not extensively applied yet, rather than in aerospace and biomedical ... -
Microstructure and mechanical properties of Ti-5Al-2.5Fe alloy produced by powder forging
(Trans Tech Publications, 2018)Blended elemental powder metallurgy is a cost effective approach to produce near net shape titanium alloy parts; however, the residual pores remaining in sintered parts are detrimental to the mechanical properties. In this ... -
No Effect of Muscle Stretching within a Full, Dynamic Warm-up on Athletic Performance
(Lippincott Williams & Wilkins, 2018)Purpose: This study aimed to examine the effects of static and dynamic stretching routines performed as part of a comprehensive warm-up on flexibility and sprint running, jumping, and change of direction tests in team sport ... -
Promoting community socio-ecological sustainability through technology: A case study from Chile
(Springer, 2017)The importance of community learning in effecting social change towards ecological sustainability has been recognised for some time. More recently, the use of Information and Communication Technology (ICT) tools to promote ... -
Collective writing: An inquiry into praxis
(2017)This is the second text in the series collectively written by members of the Editors' Collective, which comprises a series of individual and collaborative reflections upon the experience of contributing to the previous and ... -
2017 External monitoring report of the Te Paritūtanga o Te Reo – Bachelor of Māori Advancement programme offered by T.W.O.A.
(2017)In 2017, I was asked to return as an external monitor to conduct a follow-up monitoring visit of the Te Paritūtanga o Te Reo Bachelor of Māori Advancement programme, T.W.O.A. On the day of the visit, my role as external ... -
Kia kāpuia te reo o Tāmaki ki te Tonga: Tāmaki Makaurau ki te Tonga

Beyond the Screen: Emerging Cinema and Engaging Audiences. [Book Review]
(Sage Publications Ltd, 2016)This article reviews the book “Beyond the Screen: Emerging Cinema and Engaging Audiences”, by Sarah Atkinson. -
Chocolates for me or chocolates for you? The impact of a learning experience outside the classroom on the technological practice of two five-year-old students
(2015)Knowledge of expert practice is a key element of Technology Education (Ministry of Education, 2007), and this paper which is part of a larger study, is a brief comparative study which investigates the impact a learning ... -
Generalised domain and E-inverse semigroups
(Springer, 2018)A generalised D-semigroup is here defined to be a left E-semiabundant semigroup S in which the \overline{\mathcal R}_E-class of every x\in S contains a unique element D(x) of E, made into a unary semigroup. Two-sided ... -
An ecological approach to Understanding assessment for learning in support of student Writing achievement
(Frontiers Media S.A., 2018)In this paper, we report on a project conducted in a New Zealand primary school that aimed to enhance the writing achievement of primary school boys who were achieving just below the national standard for their age or level ... -
Obesity and breast cancer outcomes in chemotherapy patients in New Zealand - a population-based cohort study
(BMC, 2018)Background: Obesity has been reported as an adverse prognostic factor in breast cancer, but inconsistently, and under-treatment with chemotherapy may occur. We provide the first assessment of obesity and breast cancer ... -
