Abstract The results of the modification of austenitic matrix in cast high-manganese steel containing 11÷19% Mn with additions of Cr, Ni and Ti were discussed. The introduction of carbide-forming alloying elements to this cast steel leads to the formation in matrix of stable complex carbide phases, which effectively increase the abrasive wear resistance in a mixture of SiC and water. The starting material used in tests was a cast Hadfield steel containing 11% Mn and 1.34% C. The results presented in the article show significant improvement in abrasive wear resistance and hardness owing to the structure modification with additions of Cr and Ti.

Wear Time

The high manganese steel surfacing layer was deposited on Q235 steel by flux-cored wire gas shielded welding. The as-welded surfacing layer was heated at 1050[Formula: see text]C and quenched in the water, then was tempered at 300[Formula: see text]C. The microstructure, hardness and wear resistance of as-welded surfacing layer and that after heat treatment were comparatively analyzed. The results showed that compared with the as-welded surfacing layer, a large number of fine carbides dispersed in the austenite matrix for the surfacing layer after heat treatment. Meanwhile, the hardness and wear resistance of surfacing layer were slightly improved. The furrow in the abrasive wear for surfacing layer was shallower. Under the action of work hardening, the hardness of high manganese steel surfacing layer gradually increased while the loss weight decreased with the wear time less than 30 min. The hardness of surfacing layer reached the maximum and the loss weight of wear remained unchanged when the wear time was 30–60 min.

The Impact

Based on the traditional Mn13, the super-high manganese steel Mn18 was melted by means of adjusting the amount of C, Mn, adding a certain amount of alloying elements Cr, Mo etc and modification. The results show that with low-impact energy abrasive wear for 60 minutes, the wear resistance of super-high manganese steel Mn18 was greatly improved by contrast with that of Mn13, and the hardness of wear surface was increased slowly with the elapse of the wear time. However, under the high impact energy, the wear resistance of Mn18 is 1.5 times as high as that of Mn13, and the hardness of wear surface was increased to HB440 in a short time. The main wear forms were: cutting, gouging wear and plastic deformation. Typical TEM morphologies of subsurface wear structure consist mostly of high density dislocations, deformation bands.

The paper investigates the influence of alloying of high manganese steel with various materials on its wear resistance. It describes the results of differential scanning calorimetry and thermo-gravimetric analysis obtained in the process of thermal investigation of high manganese steel alloyed with different materials. The processes taking place in alloyed high manganese steel during heat treatment were considered. Besides, the paper shows the results of investigation of kinetics of oxidation of high manganese steels, temperatures of the start and completion of carbide decomposition and carbon burning; the comparative analysis of these processes was carried out. The research group determined the qualitative characteristics of the steel decarburization process depending on the implemented alloying scheme of high manganese steel. Scientific justification was given to the results obtained in the research work. The technological recommendations, which make it possible to calculate the optimum hardening temperature of high manganese steels, were given. General conclusions were made in the final part of the paper.

High manganese steel is a wear-resisting steel. With the rapidly development of industry, it is very important to improve the wear resistance of high manganese steel. We do some experiments with cold asynchronous rolling technique on austenitic high manganese steel.The results show that hardness and impact abrasion resistance are enhanced greatly with the increase of deformation, and the toughness not decrease to very low.

The effect of destabilization heat treatment on the microstructure, hardness, fracture toughness and abrasive wear resistance of high chromium hardfacing was investigated. The results from the study shows that the hardness, frac­ture toughness and abrasive wear resistance are influenced by temperature of destabilization heat treatment and air and furnace cooling conditions, respectively. Destabilization treatment of materials by furnace cooling caused higher secondary carbides in the dendritic austenite whilst by air cooling it showed smaller particles of secondary carbide. Also, it was found that destabilization temperature at 1,000°C improves hardness compared with hardfacing after weld depositing. The study, however, indicated that Palmqvist fracture toughness method is a useful technique for measuring the fracture toughness of high chromium hardfacing compared to Vicker’s hardness method.

The test used casting process to alloy the traditional high manganese steel with adding Ti. The surface morphology of the high manganese steel sample was observed by the scanning electron microscopy.At the same time, the hardness, the tensile strength and the wear resistance of the sample were tested. Compared with the high manganese steel without alloying, it studied the micro-structure and properties of modified high manganese steel . The results show that the grain of high manganese steel alloyed by titanium alloy is refined, the inclusions is dispersed and their size is reduced. The hardness of high manganese steel is increased by 87 %~263 %, but the tensile strength is reduced. Compared with the sample without added titanium element, the wear resistance of the alloyed high manganese steel is significantly improved.

This paper presents the results of tribological tests performed on a T-11 pin-on-disc type, which made it possible to determine the intensity of abrasive wear of steel 20MnCr5 subjected to selected thermo-chemical heat treatments. The tested steel, after the hardening and tempering process, is characterized by high endurance parameters and is used on heavily loaded machine parts. It is frequently used for elements subjected to intense abrasion. The analysis involved the following: carburizing, boronizing, and various methods of diffusion chromizing. For large loads, it is advisable to apply boronizing or carburizing with hardening. Chrome plating entails a very thin layer of increased hardness, which is characterised by a low abrasive wear resistance at high loads.
