In this work ADI-iron has been studied with a main focus on fatigue properties. ADI is a rather new set of materials with in many cases improved properties as compared to standard iron, and may in some cases even replace wrought materials. The composition range, as well as heat treatment parameters is rather narrow so a careful production control is necessary. In the experimental part of this work the fatigue properties of an ADI treated iron (austenetised at 880°C and ADI treated at 400°C) has been tested on hour glass shaped specimens. The material exhibited a fatigue strength at 106 cycles of ~480 MPa (stress range, R=0), see figure A2. The fatigue initiation was controlled by defects, i.e. pores, in the material.
