Study on the Microstructure and Property of Manganese Steel Composites Strengthened by Ceramic

Abstract

The high manganese steel composites were successfully developed by different processes. The connection of high manganese steel-ceramic, the microstructure and abrasion performance of the composites were researched by SEM, mainwhile the connection mechanism and wear mechanism were studied. The results show that the grains of the matrix are refined; the connection is fine; the connection mechanism is diffusional bond; The wear surface had relatively shallow gully; Typical TEM morphologies of super-high manganese steel was high density dislocation, deformation bands, twin.

Changes in Abrasion Resistance of Cast Cr-Ni Steel as a Result of the Formation of Niobium Carbides in Alloy Matrix

“…A review of the literature discussing problems of the wear behavior of various materials indicates that current research and development activities mainly focus on the study of dual-phase and multi-phase alloys, including cast austenitic steel whose matrix is reinforced with carbides and nitrides [ 11 , 12 , 13 , 14 ]. More and more often, precision castings for use as parts of industrial machines exposed to rapid wear are expected to keep their dimensions within narrow tolerances; otherwise, the efficiency of the entire device decreases and parts must be replaced with new ones.…”

Changes in Microstructure and Abrasion Resistance during Miller Test of Hadfield High-Manganese Cast Steel after the Formation of Vanadium Carbides in Alloy Matrix

“…The use of improved grades of high-manganese cast steel with primary and secondary vanadium carbides should additionally increase the abrasion resistance, which is very important for the working conditions of the entire set, because shanks are also prone to wear during operation of the whole set of both components, Figure 1 b. To achieve this purpose, a lot of attention has been paid to other processes [ 3 , 4 , 5 ] or techniques of synthesis [ 2 , 6 ]. The aim of the present study was to obtain the required microstructure and hardness of cast parts, and to compare their properties with those of Hadfield cast steel.…”

“…Most high-manganese grades ( Table 1 ) are characterized by a high degree of strain-hardening due to the transformation of austenite into ε—martensite or α’—martensite, or due to the occurrence of mechanical twinnings [ 6 , 7 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. However, current research and development activities mainly focus on dual-phase alloys [ 2 , 4 , 6 ], including high-manganese cast steels, whose matrix is reinforced with carbides and nitrides [ 2 , 4 , 5 ]. Castings for industrial applications become parts of machines that need to be replaced, even if they only suffer a loss of a few millimeters.…”
