“…Therefore, these composites can be used for structural applications in the wear industry. 3 In recent years, researches concerning the influence of the different ceramic particulates (TiB 2 , TiC, Al 2 O 3 , Y 2 O 3 , SiC) on the tribological properties of stainless steels were realized. Also, an improvement in the wear resistance has been observed when intermetallic particles were used as the reinforcement of the steel-matrix composites.…”

Austenitic stainless-steel specimens reinforced with aluminium oxide (Al2O3) nanoparticles added in (0.5, 1.0 and 2.5) w/% concentrations were produced by a conventional casting route. The produced composite specimens were analysed in terms of microstructural properties and wear resistance. The pin-on-disc testing method was used to study the wear behaviour of the composite at room temperature, including steady-state coefficient of friction, the running-in behaviour and wear resistance. A hardened stainless-steel ball (X47Cr14) with a diameter of 10 mm and hardness of 490 HV1 was used as a loading counter-body, sliding against an investigated disk specimen. Microstructure observations revealed that the concentration and size of the particles have an impact on the distribution of the reinforcement within the matrix as well as on the wear behaviour. The Al2O3 particles increased the hardness and consequently led to improved tribological properties of the composites.

“…Although Young's modulus of carbides are high, they are thermodynamically unstable in the iron matrix. Owing to dissolution of iron from the steel matrix by carbides and the production of complex iron compounds, the final product's Young's modulus is significantly reduced [75][76][77][78][79].…”

The present review focuses on the recent development of steel matrix composites and their advancement. Stainless steel has broad application but its critical drawbacks, such as poor hardness and wear resistance, confine its extensive application. Nowadays, steel matrix composites with ceramic particles reinforcement are finding increased interest to researchers owing to the combined effect of hard reinforcement and ductile metal matrix. TiB2 ceramic particles have exceptional properties which makes it more suitable reinforcement for steel matrix. This review summarises the different powder metallurgy assisted methods for the fabrication of steel matrix composites and their mechanical properties, strengthening mechanisms, wear performance. With the help of this review article, researchers and industrial engineers can adopt the appropriate method to meet the demands of industrial applications.

“…Here TiB2 is in equilibrium with Fe containing between 0 and 5.5 at% Ti which is applicable to MA steels The system has been up-dated by Raghavan 41 and recently by Antoni-Zdziobek et al 42 Much of the current interest in the Fe-Ti-B system is due to the development of high strength, high modulus MMC steels containing 10-20 vol.% of TiB2,These are of particular interest to the automotive industry, 42,43 but out-with the scope of MA steels. Little is available on more complex systems containing C and N, except to note that in the Fe-Ti-B-C system, increasing C leads to the formation of TiC in addition to FeB2.…”

For many years titanium has been regarded as a relative minor element in microalloyed steels compared with niobium and vanadium. However, over the past decade or so, titanium compounds in microalloyed steels have been recognized as having a wider role than just involved in austenite grain refinement.This is considered in the present review. The background and brief history are followed by sections dealing with the physical state of titanium and compounds of titanium, including borides, carbides, nitrides, oxides and sulphides characterized in MA steels. Many of the investigations on the solubility of these compounds in iron, and the precipitates they form, are considered, which leads to their functions in controlling the mechanical and toughness properties of MA steels.This now often involves the multiple alloying additions of titanium, niobium and vanadium with both carbon and nitrogen, and the morphologies of the various precipitates characterized in MA steels is presented. Titanium has become an important element in the development of line pipe steels, which for the higher grades have moved to bainite/acicular ferrite microstructures. The influence of Ti in the nucleation of acicular ferrite is an active research area, particularly with regard to the use made of titanium compounds in welding of MA steels. Finally, consideration is given to the influence of titanium on hot ductility and how titanium additions behave during continuious casting and thin slab direct charging processes.
