Materials World November 2019

This month we look at upscaling and improving upon essential materials, including magnetics, for instance, getting to grips with using a gelcasting process to produce ferric magnetic cores.

Some believe the production of wide bandgap width semiconductors could be significantly improved by a transition from manufacturing individual elements that need to be assembled, to manufacturing fully integrated units including sensitive components such as power devices and sensors. Magnetic materials have acted as the current limiting factor in this switch, but research into soft ferrites has suggested a way to overcome this. Read more on page 28.

On the same theme, we learn about new magnetic materials being developed using polarised X-ray imaging technology, and speak to an instrument scientist about how research into the behaviour of iron under high pressure is helping inform undersandings about the properties of planets.

We also look into a new grade of duplex stainless steel that’s improving performance of plate heat exchangers, the intricacies of growing industrial diamonds for very heavy-duty cutting tools, the benefits of deploying mobile solar plants at remote mining sites for energy security, and how composites and welding techniques can help reduce electric vehicle weights.

Enjoy!
