Docentföreläsning

Teknologie doktor Magnus Wessén, Material och Tillverkning - Gjutning håller docentföreläsning med titeln "SSM - Semi Solid Metalö casting - "The future casting process over the last 40 years".

Summary:

Casting is often found to be the most cost‐efficient production method for shaped metal components. For more than 5000 years molten metals have been poured into some kind of cavity to produce shaped castings. In the early 1970’ies it was found that metals in a semi‐solid state, hence consisting of solid particles distributed in a liquid, can be used in shaping operations, and that this could give several technical advantages as compared to traditional liquid casting processes.

Large resources have been spent over the last 40 years to investigate the possibilities with semi solid metal (SSM) casting, but also to develop commercial techniques based on the new ideas. Today there are even international scientific conferences entirely dedicated to SSM technologies.

Due to the large benefits observed, SSM has ever since its discovery been referred to as the “Future casting process”. However, this is still the situation of today, and there are relatively few breakthroughs in the area. The lecture will give a technical background and a state‐of‐the‐art overview of SSM applications in general, and a somewhat more in‐depth description of the Rapid S process, developed at the School of Engineering, Jönköping University, during the last 5 years.

Could the Rapid S process help to change the situation, and to

establish SSM as one of the state‐of‐the‐art techniques for production of high integrity castings?
