Abstract. The production of composite materials using Hot Isostatic Pressing (HIP) technology is finding more and more applications. Composite parts for co-rotating twin screw extruders have been introduced in practice for years and are indispensable. Further applications in the roller sector for the processing of high-quality sheet metal and wood pellet production contribute to quality improvement and service life extension and can be tailored precisely to the demands. Composite material is particularly advantageous for large dimensions. Requirements such as high hardness in the rim zone and high strength in the load-bearing core can be combined with different materials. In the present work, HIP composite materials and HIP solid materials were compared with melting metallurgically produced solid materials. The differences in hardness and strength in the rim zone and in the core after heat treatment are presented, showing the advantages and disadvantages of both systems. The choice of composite material depends on the requirements and can cover contrary needs such as corrosion, wear resistance and high strength.
