“…In the metallurgical literature, Ti 2 SC is usually referred to as Ti 4 C 2 S 2 , since it has long been found as an inclusion phase in steels and superalloys. [198][199][200] The strain induced precipitation of Ti 2 SC and its possible self-lubricating properties 199,200 are fruitful areas of the study of other MAX phases. It is interesting to note that Ti 2 SC is the hardest among the MAX phases reported to date and also possesses the highest stiffness (Table 1).…”

The MAX phases are a group of layered ternary compounds with the general formula M nz1 AX n (M: early transition metal; A: group A element; X: C and/or N; n51-3), which combine some properties of metals, such as good electrical and thermal conductivity, machinability, low hardness, thermal shock resistance and damage tolerance, with those of ceramics, such as high elastic moduli, high temperature strength, and oxidation and corrosion resistance. The publication of papers on the MAX phases has shown an almost exponential increase in the past decade. The existence of further MAX phases has been reported or proposed. In addition to surveying this activity, the synthesis of MAX phases in the forms of bulk, films and powders is reviewed, together with their physical, mechanical and corrosion/oxidation properties. Recent research and development has revealed potential for the practical application of the MAX phases (particularly using the pressureless sintering and physical vapour deposition coating routes) as well as of MAX based composites. The challenges for the immediate future are to explore further and characterise the MAX phases reported to date and to make further progress in facilitating their industrial application.

“…13,26,28,29,30) The present system follows the same trend as the one found in Ti IF steels and it is presented as an alternative route to stabilize interstitial elements. Owing to the formation of titanium nitride and titanium carbosulfide precipitates, it makes sense to suggest that those secondphase particles have removed carbon and nitrogen interstitial free elements from dislocations and explains the continuous yielding found in the engineering stressstrain curves of the TiO 2 inoculated low carbon steel.…”

Mechanical Properties and Phases Derived from TiO<sub>2</sub> Nanopowder Inoculation in Low Carbon Steel Matrix

The effect of TiO 2 nanoparticle addition on mechanical properties of low carbon steel and the phases originated from this inoculation were investigated. Equilibrium phases were estimated by means of thermodynamic modeling and the results were compared with further microscopy characterization. Both techniques confirmed the dissolution of TiO 2 nanoparticles in the molten steel which derived in TiN and Ti 4 C 2 S 2 nanometric reaction products. The formation of these nanometric phases, were found to result in ferrite grain refinement and consequently in the enhancement of mechanical properties. In addition, the formation of these phases led to C and N depletion from the iron matrix and to a continuous yielding behavior in tensile stressstrain curves.

“…This fact suggests that the deformation helps the nucleation of Ti 4 C 2 S 2 in the γ matrix. Recently, the precipitation behavior of the strain-induced Ti 4 C 2 S 2 was carefully observed by Regone et al [29]. The decrease in the annealing temperature brings about the increase of the driving force for precipitate of Ti 4 C 2 S 2 , although TiS precipitates in the matrix.…”

“…These precipitates have significant effects on both texture and mechanical properties of IF steels. Therefore, many studies have been carried out on precipitation behavior of sulfides, carbides and carbo-sulfide [19][20][21][22][23][24][25][26][27][28][29]. Furthermore, evaluations of the solubility products of TiS and Ti 4 C 2 S 2 in the γ phase have been conducted to predict the precipitation behavior [25,27,[30][31][32].…”

A database for thermodynamic information of sulfides and carbo-sulfide in steels has been developed, where the thermodynamic properties of the relevant constituting sub-system of the complex system have been assessed by the CALPHAD (Calculation of Phase Diagrams) approach. The utility of this database is demonstrated in examples of phase diagram calculations of low carbon steels and stainless steels. The calculated results are in good agreement with experimental data. The developed thermodynamic database would be useful in predicting the formation of sulfides and carbo-sulfides in the commercial steels.
