Industry 4.0 and the Powder Metallurgy industry: Challenges and opportunities ahead
Computers and the internet affect all sectors of our lives and have led to profound changes in industrial production. Through growing digitalisation and the integration of ever more advanced artificial intelligence, the ability for systems to respond to external circumstances without human intervention is just one aspect of what has come to be known as the fourth industrial revolution, or ‘Industry 4.0’.
Just how and to what degree this could affect the Powder Metallurgy industry has been the subject of several recent presentations at technical conferences. In this article, Dr Georg Schlieper offers a look at the challenges that Industry 4.0 brings to the PM industry, and highlights the opportunities that could lie ahead.

New opportunities for master alloys: Ultra-high pressure water atomised powders
Research began on the development of master alloys (MAs) for PM steels some fifty years ago. Over the years, a number of master alloys have shown promise, but the wide adoption of these was prevented due to the need for high sintering temperatures and the excessive tool wear caused by the very hard and angular MA powder particles.
In this article, Dr Raquel de Oro Calderon of the Institute of Chemical Technologies and Analytics at TU Wien, Austria, reports on work that makes use of ultra-high pressure water atomised master alloy powders and could significantly increase the hardenability of commercial steel powders at a very low alloying cost.

Euro PM2018: Powder Metallurgy processing by hot pressing technologies
Several papers presented at the Euro PM2018 Congress and Exhibition, organised by the European Powder Metallurgy Association (EPMA) and held in Bilbao, Spain, October 14–18, 2018, addressed developments to enhance the understanding of process control in hot pressing technologies.
In this report, Dr David Whittaker discusses two papers focused on the numerical simulation of Hot Isostatic Pressing (HIP) using Finite Element Modelling, and a further paper on the impact of W particle size on the diffusion and porosity of hot pressed chromium-based compounds.

Hagen Symposium: How Powder Metallurgy can meet the needs of a changing market
The annual PM symposium at Hagen, Germany, organised by Fachverband Pulvermetallurgie, brings together the German-speaking PM community for two days filled with technical presentations on all sectors of PM technology, an accompanying exhibition of PM raw materials and equipment suppliers and a social event on the eve of the conference.
This year, the Hagen Symposium welcomed 200 participants and 51 exhibitors, and for the first time, a day of practical training with workshops on compaction, sintering and inspection was offered in conjunction with the symposium programme. Dr Georg Schlieper visited the symposium on behalf of PM Review.
