Hoeganaes Innovation Centre: Technical support and powder development for the next generation of PM applications
Hoeganaes Corporation is one of the world’s largest manufacturers of metal powders, supplying an ever wider range of materials and grades to a growing customer base. Earlier this year the company invited Powder Metallurgy Review to visit its Innovation Centre in Cinnaminson, New Jersey. PM Review’s Paul Whittaker reports on how the company not only develops powders for the next generation of PM processes, but also offers support to customers in the development of new PM applications and troubleshooting production issues.

The master alloy route: Introducing attractive alloying elements in Powder Metallurgy steels
The use of Cr, Mn and Si as alloying elements could offer improved properties in sintered steels whilst at the same time reducing powder costs. Successful sintering of these powders is, however, a challenge that requires deep knowledge of the chemistry behind the sintering process. Dr Raquel de Oro Calderon describes work undertaken by her and colleagues at TU Wien that identifies the master alloy route as a promising solution to address the challenges of applying these elements.

Powder Metallurgy fundamentals: An introduction to the principles of sintering metal powders
Understanding the principles of sintering is essential for all who work with metal powder based technologies. In this overview of the sintering process Professor Randall M. German looks at the interplay between temperature, particle size and heating time and explains how these factors impact on the final products. Many combinations of these adjustable parameters provide similar levels of sintering, reflecting how the process required to sinter a powder can be delivered in many forms. Options range from short times with small particles at high temperatures to long times with large particles at modest temperatures.

Improving quality control through effective particle characterisation of metal powders
Advances in Powder Metallurgy production technologies are generating an increased demand for tailored and tightly controlled powders with distinctive properties. The control of particle size distribution, as well as particle shape, is an important step in the quality control process. In this article Jörg Westermann, Retsch Technology GmbH, compares the three most commonly used methods for powder characterisation and highlights the pros and cons of each process.
