Opis:: The results of study of austempered ductile iron using different methods of austempering are presented. Except changing time, temperature of austenitizing and isothermal quenching, direct quenching, two-step quenching followed solution heat treatment (austenitizing) was proposed. The goal of this paper is to discuss the results obtained for ductile cast iron subjected two step austempering. Ultimate tensile strength, elongation, hardness, and fracture toughness, thermal stability were compared. Two-step quenching method of hardening seems to be promising.

Opis:: The results of comparison of the wear resistance of manganese steel X120Mn12, S235IR steel and austempered ductile iron ADI are presented. The aim of this study is to determine the possibility of replacing an item made of X120Mn12 steel with another material. For this purpose, all of the samples were measured for Brinell hardness. The samples were then tested for wear resistance in a specially designed test stand. The test resided in shot penning the surface of the test samples within the shot stream with the defined parameters. The test stand used in the test ensured the shot penning parameter stability. The test samples underwent multiple tests in which shot penning occurred in reccurrent cycles. Three test limits were established for the present study: 60, 120 and 180 cycles. The wear resistance measure in this study was the decrease in the tested sample’s weight expressed in grams and calculated for a unit of the shot-penned surface. The obtained results confirmed the possibility of using ADI as a possible replacement of manganese steels in specific cases. Of the eight types of the samples tested, the two ADI samples exhibited abrasion resistance which was comparable to that of the reference sample, while one exhibited better resistance. What constitutes the optimal chemical composition and the corresponding optimal heat treatment for particular cases remains an issue for further research.

Opis:: Ductile iron casts with a higher silicone content were produced. The austempering process of high silicone ductile iron involving different austempering times was studied and the results presented. The results of metallographical observations and tensile strength tests were offered. The obtained results point to the fact that the silicone content which is considered as acceptable in the literature may in fact be exceeded. The issue is viewed as requiring further research.

Opis:: The results presented in this paper are a continuation of the previously published studies. The results of hest treatment of ductile iron with content 3,66% Si and 3,80% Si were produced. The experimental castings were subjected to austempering process for time 30, 60 and 90 minutes at temperature 300^oC. The mechanical properties of heat treated specimens were studied using tensile testing and hardness measurement, while microstructures were evaluated with conventional metallographic observations. It was again stated that austempering of high silicone ferritic matrix ductile iron allowed producing ADI-type cast iron with mechanical properties comparable with standard ADI.
