title: Producing High-Quality Titanium Alloy by a Cost-Effective Route Combining Fast Heating and Hot Processing

authors: Yang, Fei

subjects: Science & Technology

abstract: 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. In this paper, we will discuss a possible cost-effective route, combining fast heating and hot processing, to produce titanium alloys with similar or even better mechanical properties than that of ingot metallurgy titanium alloys. Two titanium alloys, Ti-5Al-5V-5Mo-3Cr (Ti-5553) and Ti-5Fe, were successfully produced from HDH titanium powder and other master alloy powders using the proposed processing route. The effect of the processing route on microstructural variation and mechanical properties have been discussed.

title: Impact of classroom design on interactive whiteboard use in a special needs classroom

authors: Shannon, Grant

subjects: computer science

abstract: The physical environment of a classroom—how space is organized and controlled—impacts the use of technology within that setting. This paper presents the initial rationale for choosing an interactive whiteboard (IWB) as the platform for software designed to encourage play in primary students with Autism Spectrum Disorders. An observational study of normal classroom practice and of an installed version of the software uncovered factors in the physical installation of the IWB and its pedagogical use that negatively affect its potential use.

title: Approaches to benefit sharing

authors: Sterling, Rogena

abstract: This information sheet provides successful examples of different approaches to benefit sharing across a range of industries, from around the world and within Aotearoa. It highlights what works and where challenges and gaps exist in current approaches. Finally, a spectrum of Indigenous sharing approaches is provided, based on the OECD framework of benefit sharing and type of benefit (direct and collective) to Indigenous peoples.
