“…6,13,14 The strengthening mechanism responsible for the steels studied mainly comes from the load bearing capacity of TiC reinforcement occurring during elastic deformation. In addition, the tiny particles, acting as barriers to dislocation motion, may also be contributing to this.…”

The microstructure, creep and oxidation properties of TiC particulate reinforced 304 stainless steels prepared using a new developed technology have been investigated. Experimental results show that small amounts of TiC addition to 304 stainless steel results in an increase in yield and tensile strength but a decrease in ductility over the temperature range 600-800uC. A reduction in strength occurs when excessive TiC is introduced. Creep properties of TiC reinforced steels are significantly higher than that of 304 stainless steel without TiC addition at temperatures between 700 and 800uC and under an applied stress of 55 MPa. Addition of TiC particles results in no breakaway oxidation, and a low oxidation rate is maintained in air at 850uC for 96 h oxidation, but oxidation resistance will significantly decrease if excessive TiC is added. In addition, adding TiC causes excellent spalling resistance.

“…The inclusion of TiC in high titanium steel has the characteristics of low density and high hardness, which can be used to improve the wear resistance of materials [ 5 , 6 ]. In addition, if Ti and N in high titanium steel form stable titanium compound TiN during the solidification process, it can hinder the migration of austenite grain boundary, further refine austenite grain and improve the strength and toughness of the steel [ 7 , 8 ].…”

“…TiC precipitates in the form of a eutectic reaction in high Ti steel, so the size of the precipitate is large. Eutectic TiC has the characteristics of low density and high hardness, so it can be used to improve the wear resistance of materials [ 9 , 10 ]. The toughness and plasticity of high titanium wear-resistant steel do not decrease but increase with the increase of strength, which is mainly due to the refinement and homogenization of large-size TiC during rolling deformation [ 11 ].…”

The investigation of precipitation behavior of titanium compounds for high titanium steel based on in situ observation

et al. 2023

The effects of cooling rate, Ti content, and casting temperature on titanium compounds for high titanium steel were investigated. In-situ observation of high titanium steel during remelting and solidification was carried out by using a High Temperature Confocal Scanning Laser Microscope (HTCSLM), and the observed results were in good agreement with the thermodynamic and kinetic calculations. The observation and calculation results both show that the inclusions in high titanium steel first precipitate in the form of TiN, followed by TiC precipitates as temperature decreases, eventually forming TiCxN1-x type inclusions at room temperature. The initial precipitation temperature of the inclusions increases with the increase of Ti content in molten steel, whereas casting temperature has little effect on the initial precipitation temperature of inclusions. In addition, the size of TiN inclusions increases with the increase of Ti content in steel but decreases with the increase in cooling rate.

The corrosion behavior of TiC particle-reinforced 2Cr13 stainless steels prepared by in situ reaction and electroslag remelting (ESR) was investigated using potentiodynamic polarisation measurements and immersion tests. The addition of TiC particles to 2Cr13 stainless steel impeded rapid pit propagation but maintained a high corrosion rate in the whole immersion time investigated. The TiC addition developed finer matrix structure, the formation of Cr-rich carbides and high dislocation density around the TiC particles before corrosion, which results in an increasing corrosion rate and preferential pitting attack at the steel matrix/TiC interface. Although the corrosion resistance of 2Cr13 stainless steel is sharply decreased due to TiC addition, it is significantly improved after the ESR process. This is attributed to the more uniform distribution and smaller size of TiC particles, the increase of value of x in TiCx and the elimination of the porosity in TiC particle-reinforced 2Cr13 stainless steel after the ESR process.
