“…This is attributed to the precipitation of TiCs, which served as heterogeneous nucleation sites for liquid steel. The present result is consistent with the findings that the addition of titanium in high-carbon high-chromium steel or cast iron could refine the eutectic carbides M7C3 and the grain size of the steel as reported by other researchers [26,27,29].…”

Abstract:The effect of titanium on the carbides and mechanical properties of martensitic stainless steel 8Cr13MoV was studied. The results showed that TiCs not only acted as nucleation sites for δ-Fe and eutectic carbides, leading to the refinement of the microstructure, but also inhibited the formation of eutectic carbides M 7 C 3 . The addition of titanium in steel also promoted the transformation of M 7 C 3 -type to M 23 C 6 -type carbides, and consequently more carbides could be dissolved into the matrix during hot processing as demonstrated by the determination of extracted carbides from the steel matrix. Meanwhile, titanium suppressed the precipitation of secondary carbides during annealing. The appropriate amount of titanium addition decreased the size and fraction of primary carbides in the as-cast ingot, and improved the mechanical properties of the annealed steel.

“…It was reported that the friction heat promotes the formation of oxide layer of Fe 2 O 3 or Fe 3 O 4 when the surface temperature increases over 130°C. 18) These oxides reduce not only the friction but also the wear loss because of the effect of solid lubricant. At the low temperature, however, the wear behavior is dominated by the abrasive wear.…”

“…At the low temperature, however, the wear behavior is dominated by the abrasive wear. 18,19) In this experiment, the temperature of test specimen is increased a little from the room temperature, say, at most 50°C. From this viewpoint, it can be safely said that the effect of friction heat on the wear behavior in Suga wear test is very less.…”

Hypoeutectic 26 mass% Cr cast irons with 03 mass% Mo were prepared in order to investigate their abrasive wear behavior. The annealed test pieces were hardened from 1323 K and then tempered at three levels of temperatures between 673 and 823 K for 7.2 ks, the temperature giving the maximum hardness (H Tmax ), lower temperature than that at H Tmax (L-H Tmax ) and higher temperature than that at H Tmax (H-H Tmax ). The abrasive wear resistance was evaluated using Suga wear test (two-body-type) and Rubber wheel wear test (three-body-type). It was found that hardness and V £ in the heat-treated specimens varied depending on the Cr and Mo contents. A linear relation was obtained between wear loss and wear distance. The lowest wear rate (R W ) was obtained in both the as-hardened and H Tmax specimens. The highest R W was mostly obtained in the H-H Tmax specimens. Under the same heat treatment condition, the R W in Suga wear test was much greater than that in Rubber wheel wear test. The R W decreased with increasing hardness. The lowest R W obtained in the specimen with a certain amount of retained austenite, 1015%V £ . The R W decreased with increasing Mo content in Suga abrasive test and it decreased little by Mo addition in Rubber wheel wear test.

“…Here, additions of alloy elements have been used to form the NaCl type carbides, such as Ti, Nb, V etc. [2][3][4][5][6][7][8][9] For Ti additions, it was reported that the NaCl type carbide such as TiC carbide can act as heterogeneous nuclei for the precipitation of M7C3 type carbides during the cooling and solidification of the melt. [2][3][4] This, in turn, results in significant refinements of the final carbides size.…”

Effect of Cooling Rate and Ti Addition on the Microstructure and Mechanical Properties in As-cast Condition of Hypereutectic High Chromium Cast Irons

The effect of cooling rate and Ti additions on the mechanical properties and carbides characteristics such as morphology, size distribution and composition was studied in high-chromium cast irons containing Fe-17 mass%Cr-4 mass%C. Based on the size distribution, composition and morphology, M7C3 type carbides were roughly classified into "primary M7C3 carbides" and "eutectic M7C3 carbides" with a 11.2 μm border size. Thereafter, the change of the solidification structure and especially the refinement of carbides size were determined. It was found that both the size and number values should be summarized systematically for primary M7C3 carbides and eutectic M7C3 carbides, respectively. Also, TiC carbides with a high formation temperature can not only act as a nuclei of M7C3 carbides, but they also contain a Ti(C, N) core. In the as-cast condition, the bulk hardness of the cast irons increases with an increased Ti content. In addition, the wear loss increases with an increased Ti content. Neither the bulk hardness nor the wear loss did change too much with an increased cooling rate.
