“…this technique provides an excellent surface finishing and increases the service life of the cutting tools five times more [9, 26,31]. 7. the welding process of austenitic manganese steel a lot of researche into the welding process of Hadfield steel has been done [14,15,34]. according to m. Sabzi [14], it is first of all important to determine the shape of the welded joints, because it affects the durability of the welded part.…”

“…the latest has higher: toughness, ductility, impact energy and good corrosion resistance because it contains less carbide than the V-shaped chamfer. V. jankauskas [34] reinforced basic Hadfield steel and Hadfield alloy steel with cr, Ni, mo and B by tungsten carbides, that reduced the amount of austenite in the structure and promoted good wear resistance under low applied load, but exhibits moderate wear resistance under high abrasive and erosive conditions. S.m.…”

Forming the structure and the properties of electric arc coatings based on high manganese steel alloyed with titanium and niobium carbides

“…Ключовi [6,7]. Electrode materials of the Fe-Mn-C system demonstrate high performance under working conditions when there are significant dynamic loadings and are widely used in strengthening the parts of earthmoving equipment, milling facilities, mining equipment, etc.…”

“…An increase in wear resistance of such coatings can be achieved by insignificant ~1.2 % by mass of V [6], which ensures an increase in initial hardness up to 35 HRC. In paper [7], the effect of alloying on hardness and impact wear resistance of electric arc coatings based on the Fe-Mn-C system was studied. The results showed that during the transition from the doping system Fe-Mn-C to the Fe-Mn-W-C system (the content of W is 19 % by mass), the hardness of coatings increases from 11 HRC to 36 HRC.…”

“…7) shows that the use of ferro silicomanganese (E1 material) in the charge enables obtaining the coating with almost similar level of properties. Additional alloying of the charge with Ti and Nb carbides leads to a significant increase in hardness both in the welded (12-13 HRC), and deformed state (6)(7)(8). This increase in hardness due to the appearance of carbide phases in the structure leads to a natural increase in abrasive wear resistance by 1.6-1.8 times.…”
