Iron based cellular structures - status and prospects

Cellular metals based on iron have been intensively investigated during the last two decades. Because of the significant decrease in of the structural density of iron based cellular structures, numerous technologies have been developed for their manufacturing. Besides the tremendous weight reduction a combination with other properties like energy and noise absorption, heat insulation and mechanical damping can be achieved. This contribution will give an overview about the latest state in iron based cellular materials, including technologies in manufacturing, properties and potential applications.
