“…It can perform best in gouging abrasion conditions such as in dragline brackets, gyratory rock crushers, roll crushers, jaw crushers and among others, where toughness is a prime requirement. The machining of this type of steel is difficult because of its hardness, low thermal conductivity and strain hardening behavior [1][2][3][4].…”

The gouging abrasion resistance, hardness and microstructural properties of austenitic manganese steel were investigated as influenced by the varying amount of titanium addition. The gouging abrasion of the steel sample with 0.1 % titanium had the least amount of material loss and showed the highest work hardening effect. The alloying process to 0.2 % was detrimental to its mechanical properties. There was an increase in the hardness from 0 to 0.1 % titanium addition and a decrease at 0.2 % titanium content. Metallurgical surface examination of the unmodified austenitic manganese steel revealed the formation of manganese sulfide micronodules and grain boundary carbide. The titanium modified austenitic manganese steel showed titanium-containing precipitates, which increases the strength and toughness of the steel material as well as the resistance of the material to slip and plastic deformation through the precipitation hardening and grain size refinement mechanisms.

“…Because of its unique properties such as hardness, wear resistance, strength and low thermal conductivity, this material has recently been commonly utilized in many engineering operations involving mining equipment, excavators, railways, pumping equipment, rolling-mill parts for steel factories and wear-resistant components of machining elements 18,19 . Test samples in the size of 10 mm × 20 mm × 200 mm were prepared.…”

In this study, a new system for drilling deep micro-holes was designed for Hadfield steel (which is difficult to process with classical methods) with the electro-discharge-machining method (EDM) and the system was experimentally examined. The tests were carried out at three different discharge currents (6, 12 and 24) A, three different electrode-tool rotational speeds (200, 400 and 600) r/min, three different dielectric spray pressures (40, 80 and 120) bar, a constant pulse duration (12 μs) and a constant pulse interval (3 μs). After the tests the effects of the processing parameters on the basic performance outputs (the material removal rate -MRR), the electrode wear rate (EWR) and the relative wear (RW)) were investigated. Additionally, an analysis of variance (ANOVA) was also applied to identify the most significant factor. Optimum operating parameters were determined using the desirability-function analysis through the response surface methodology (RSM). It was found that the most effective variable affecting the MRR, EWR and RW was the discharge current. The discharge current was found to be the most significant control factor influencing the performance of the machining process. Keywords: deep micro-EDM, hole drilling, Hadfield steel, multi-response optimization, ANOVA V tej {tudiji je bil postavljen nov sistem za vrtanje globokih mikrolukenj v jeklo Hadfield (ki se te`ko obdeluje z navadnimi metodami) z metodo elektroerozije (EDM) in bil tudi eksperimentalno preizku{en. Poskusi so bili izvedeni s tremi razli~nimi tokovi (6, 12 in 24) A, pri treh razli~nih hitrostih vrtenja orodja (200, 400 in 600) r/min, pri treh razli~nih dielektri~nih tlakih razpr{evanja (40, 80 in 120) bar, pri konstantnem trajanju impulza (12 μs) in konstantnem intervalu impulza (3 μs). Preiskovani so bili u~inki procesnih parametrov na zmogljivost (hitrost odvzema materiala (MRR), stopnja obrabe elektrode (EWR) in relativna obraba (RW)). Dodatno je bila uporabljena analiza variance (ANOVA) za ugotovitev najpomembnej{ega faktorja. Optimalni obratovalni parametri so bili dolo~eni z analizo funkcije odziva na metodologijo odziva povr{ine (RSM). Ugotovljeno je bilo, da je razelektritveni tok najpomembnej{i kontrolni faktor, ki vpliva na zmogljivost procesa obdelave.
