High-Temperature Materials

Due to their very interesting and often unique properties intermetallics occupy a position between metallic materials and ceramics. Powder metallurgical processing routes are often preferred due to economical reasons but do also show advantages in terms of materials properties or processing (e.g. homogeneous microstructure; preparation of MMC´s or IMC´s). A special patented technique developed at Fraunhofer IFAM Dresden allows the preparation of elemental powder mixtures with high sinterability, the compaction of these powders by conventional techniques (as die pressing or cip) and finally the densification of samples and prototypes by reaction sintering.
