• The present investigation was carried out to make clear the relation between the growth of grey cast iron due to the abnormal expansion at Ar transformation and that due to the oxidation. Various kinds of dilatometer were used for this purpose. According to the authors' results, when grey cast iron is repeatedly heated at a high temperature in air, growth takes place principally due to the oxidation and the growth of this kinds is much larger than due to the abnormal expansion at Ar transformation. It is acceptable that grey cast iron becomes susceptible to oxidation by passing through its Ar critical range, hence its growth is accelerated by the oxidation. The authors cannot, however, agree with the investigators who believe that the abnormal expansion at Ar tranformation in a direct cause of growth in every case, the effect of exidation being indirect.
