“…According to the report of T. Z. Kattamis,12) in the solidification process of the FeTiC melt, the average TiC particle size decreases with increasing cooling rate for the same alloy composition. However, the average particle size also depends on the volume fraction of TiC; with increasing volume fraction, the average particle size coarsens.…”

Laser alloying using a carbon steel substrate pre-coated powder mixture of pure titanium and graphite was carried out to form an FeTiC composite surface layer for improving wear resistance. The microstructure of the composite layer was studied in detail using OM, SEM, XRD and STEM to reveal the effect of the laser alloying conditions on the distribution of carbides. Coarse particles (15 µm) and submicron particles of TiC were observed. TiC particles were distributed in a lath martensite matrix, and the area fraction of TiC was about 8 to 25%. The area fraction and size of TiC depended on the laser scanning speed. Under the condition of a high scanning speed, a composite layer with a high area fraction and a coarser size of TiC was obtained. These composite layers exhibit high hardness and superior wear resistance compared with a laser transformation hardened area of the same substrate.

“…For instance, Titanium carbide (TiC) has been recognized as one of the most important reinforcing phase especially in the Fe-base composite due to its excellent properties [3]. Indeed, the incorporation of the TiC particles into ferrous matrix lead to the increasing of wear and corrosion resistance, thermal and chemical stability, modulus of elasticity, as well as shearing and creep of the Fe-TiC composite [4][5][6].…”

Abstract: The aim of this research paper is to fabricate a Fe-TiC composite by a novel and simple manufacturing method. The latter is based on two cumulative processes; a conventional sintering (transient liquid phase sintering) and a hot forging with steam hammer respectively. The blinder phase of the studied simples is varied from carbon steel to high alloy steel using alloying additive powders. The obtained outcomes showed that after the sintering process, the relative density of the performed simples is improved from 86% to 95.8% without any densification process. Otherwise, in order to ensure maximum densification and enhance in addition the solubility of the alloying additives the hot forging process is then applied. Indeed, the final obtained composite product is a TiC-strengthened steel with a relative density around 99% (about 6.5 g/cm3 of density) wherein 30% (wt.) of spherical and semi-spherical TiC particles are homogeneously distributed in the metal matrix.

“…Recently, there has been a great deal of interest in the development of particle reinforced steel or iron matrix composites as structural materials for industrial applications. 1,2) Particle-reinforced steel matrix composites have higher strength and wear resistance than those of its matrix material, because the particle phases can strongly resist abrasive wear. [3][4][5][6][7][8][9][10] Austenitic manganese steel has excellent strength and toughness together with good wear resistance.…”

An in-situ TiC-reinforced Hadfield manganese austenitic steel matrix composite has been synthesized by conventional melting and casting route. The microstructure has been characterized using an optical microscope, a scanning electron microscope coupled with an energy dispersive spectrometer and X-ray diffraction. Hardness and abrasion resistance have also been measured. The microstructure of the as-cast composite consists of austenite, a-ferrite and (Fe, Mn) 3 C together with TiC particles. The microstructure of the solution-annealed (1 273 K for 36 ks) composite contains TiC particles in g matrix. It has been observed that the abrasive wear resistance of the solution-annealed composite is significantly better than that of the solution-annealed austenitic manganese steel.KEY WORDS: Hadfield manganese austenitic steel; in-situ steel matrix composite; titanium carbide; solution annealing treatment; abrasive wear resistance.then the temperature was raised to 1 883 K. The calculated amount of Fe-Ti (70 % purity) and electrolytic manganese (95 % purity) were added to the melt at this temperature. The Fe-Ti was added to iron alloy melt by plunging due to lower density of Fe-Ti with respect to iron alloy melt. The melt was stirred continuously at 1 893 K temperature for 600 s and subsequently cast in a metallic mould. The chemical compositions of the Hadfield manganese austenitic steel and TiC-reinforced composite are presented in Table 1.Metallographic samples of dimension 12 mmϫ12 mmϫ 10 mm were cut from the middle portion of the casting. The specimens were polished according to the standard metallographic technique and finally etched with 2 % nital. The samples were examined using an optical microscope (OM) and a scanning electron microscope (SEM) equipped with an energy-dispersive X-ray spectrometer (EDS). The various phases revealed by metallography were analyzed by the X-ray diffraction (XRD) analyses using the Co K a radiation.The macrohardness was measured using a Vickers hardness tester at an applied load of 30 kgf and loading time of 20 s at room temperature. The samples were first surface finished and then ten measurements were performed randomly in each sample. The average of ten measurements has been represented as the hardness of the specimen.Abrasive wear tests were carried out on 12 mmϫ 12 mmϫ10 mm samples against 220 grit SiC paper affixed to a rotating flat disc of 250 mm diameter. The rotating speed and the track diameter were fixed as 300 r.p.m. and 80 mm, respectively. The sliding velocity was fixed at 1.25 m/s. The experiments were carried out at the load of 24.5 N. As the TiC (2 900-3 200 HV) 20) particles in the composite are harder than SiC (2 850 HV) 20) abrasives, SiC particles get blunted after sliding for only 30 s. To ensure fresh supply of abrasive particles, worn SiC abrasive paper was replaced with a new one after 30 s. Wear rate of the specimens has been computed by the weight loss technique. The wear data has been plotted as cumulative volume loss (converted from weight loss) as a fu...
