“…This confirms the previous findings of Sugishita and Fujiyoshi [39]. Several researchers have also stated the role of graphite as a lubricant at low applied loads [23,40,41]. Research carried out by Zum Gahr and Eldis [42] supports our findings as their results indicate that approximately 28 vol.% carbide provides the best abrasion resistance for white cast irons.…”

The influence of chill thickness and applied load were studied on wear behaviour of a carbidic austempered ductile iron containing Cu and Ni. Ductile iron with chemical composition Fe-3.6C-2.6Si-0.53Cu-0.51Ni (in wt.%) was cast into standard moulds with copper end chills of different thicknesses. Wear test samples were prepared from the chilled surface of the blocks. Austenitizing heat treatment was carried out at 870 • C followed by austempering at 270, 320, 370 and 410 • C in electrically heated salt bath furnaces for optimum times. A block-on-ring testing machine was used to carry outwear tests in dry sliding condition under applied loads of 100 and 150 N. Scanning electron microscopy was used to examine the worn surface of the samples. The results indicated an improvement in wear resistance of austempered ductile iron by introducing carbides into the matrix compared to that of non-carbidic samples. Best wear performance in carbidic austempered ductile iron was achieved for a matrix containing about 30 vol.% carbides.

“…Tests also cover ADI with single additions of: -chromium [8] -manganese [9,10] -boron [11] On the other hand, the literature lacks the data on the ADI with nickel added as a single element. Studies of this subject have been undertaken in the present work and are expected to make a contribution and fill at least partially the existing gap.…”

The results of examinations of microstructure and an analysis of its impact on selected mechanical properties of austempered ductile iron (ADI) were presented in the paper. The ADI was produced from the ductile iron containing 1.56% Ni only alloying addition. The effect of the austempering time and temperature on the microstructure and mechanical properties of the examined cast iron was considered. Constant conditions of austenitizing were assumed and six variants of the austempering treatment were adopted. The studyof mechanical properties included a static tensile test, Charpy impact strength test and Brinellhardness measurement.This work complements the knowledge about alloying additions effect on microstructure and mechanical properties of ADI and focuses on the impact of a single alloying element (Ni).
