Machinability of austempered ductile iron (ADI)

 


The limited strength of conventional ductile cast iron and the constantly growing requirements on cast parts in combination with the demand on consequent weight reduction, require the use of new materials. An important development is represented by austempered ductile iron (ADI). By a special heat treatment of conventional ductile cast iron a material with particular microstructure is made. This microstructure improves the mechanical properties. A wider industrial use is hindered by a lack of knowledge about machining this material. As capable partner the WZL can hearken back to numerous industrial and research projects on machining of ADI. The current area of research range from basic research of cutting properties of ADI materials over tool, cutting material and coating characterization to a integral optimization of tool geometry.
