“…Two times more powerful than structural steel the ADI ductile iron classical quality, with other similar mechanical properties, which is primarily related to ductility and toughness. By adding titanium and boron material in the machining process with hard coated tools, it is possible to increase the hardness and abrasion resistance of the tools [25].…”

Experimental research of cutting force components during dry face milling operations are presented in the paper. The study was provided when milling of ductile cast iron alloyed with copper and its austempered ductile iron after the proper austempering process. In the study, virtual instrumentation designed for cutting forces components monitoring was used. During the research, orthogonal cutting forces components versus time were monitored and relationship of cutting forces components versus speed, feed and depth of cut were determined by artificial neural network and response surface methodology. An analysis was made regarding the consistency of the measured cutting forces and the values obtained from the model supported by an artificial neural network for the investigated interval of the cutting regime. Based on the results, an analysis of the feasibility of the application of austempered ductile iron in the industrial sector with the aspect of machinability as well as the application of the models based on artificial intelligence, was given. At the end of the presentation, the influence of the aforementioned cutting regimes on cutting force components is presented as well.

“…The strength of ADI material is up to two times that of the nodular iron of standard quality, with the same value of toughness and ductility [2]. Hardness and wear resistance can be increased by additions of titanium and boron in the hardfacings [4][5][6]. Previous studies have shown that alloying elements such as Cu and Ni influence temperature, initiation time and completion of the austempering reaction, which provides a larger processing window and easy control of the austempering heat treatments [7].…”

The influence of austempering temperature on tribological properties of austempered pearlitic ductile iron (ADI) was investigated. The as-cast ductile iron was subjected to heat treatments consisting of austenitization at 900 • C followed by austempering at temperatures of 250, 300 and 350 • C for 120 min. The austempered samples were subjected to abrasion and adhesion wear resistance tests using steel and ductile iron plates. The abrasive wear testing of the tribo-pair was undertaken with the sanding plate. The results of abrasion and adhesion wear resistance tests are presented, and the effect of austempering temperature is discussed.

“…In general, this may be combatted by either solid solution hardening of austenite or by introduction of hard particles to the steel matrix [12]. As a reinforcement, borides [13], carbides [14][15][16][17] and cermets [18][19][20][21] have been studied. Under the present research, obtaining a WC reinforced PTAW hardfacing with an austenitic matrix is attempted, and sliding wear of the obtained hardfacing is studied under room and elevated temperatures.…”

The present research focuses onto sliding wear of novel plasma transferred arc welded (PTAW) hardfacing with the stainless steel (DIN X3CrNiMo18-13-3) matrix, reinforced with WC/W2C, under the room and elevated temperature. The hardfacing was produced, applying the optimized set of parameters (current – 55 A, reciprocating speed – 1.0 mm/s, oscillation frequency – 0.6 Hz). The average reinforcement content was 29.3 ± 4.0 vol %. The reinforcement consisted of W2C and WC, while M7C3- and M23C6-type (M = Fe, Cr, Mo, W) carbides were the main phases in the matrix. Universal hardness and Young’s modulus were approximately 5.3 and 1.9 times higher, than those of the reference steel (DIN X2CrNiMo18-14-3). The sliding wear of the hardfacing was 4.9 times lower under 20 °C and 3.1 times lower under 300 °C, but 1.8 times higher under 500 °C than the wear of the reference steel. Galling was the wear mechanism of the hardfacing under 20 °C, scoring – under 300 °C and combination of scoring and binder extrusion – under 500 °C
