“…[1][2][3][4][5] The effects of additional alloying elements in high chromium irons have been extensively studied. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Normally, alloying additions such as nickel, manganese, molybdenum and copper are used to increase hardenability and to prevent pearlite formation. 2,6) High chromium irons alloyed with carbide-forming elements such as molybdenum, vanadium and tungsten have been developed for special applications such as hot working mill rolls in the steel industry.…”

Solidification of High Chromium White Cast Iron Alloyed with Vanadium

2011

Experimental results indicate that vanadium affects the solidification process in high chromium iron. Vanadium is distributed between eutectic M 7 C 3 carbide and the matrix, but its content in carbide is considerably higher. Also, this element forms vanadium carbide. TEM observation reveals that vanadium carbide present in examined Fe-Cr-C-V alloys is being of M 6 C 5 type. DTA analysis found that with increasing vanadium content in tested alloys, liquidus temperature is decreasing, while eutectic temperature is increasing, i.e. the solidification temperature interval reduces. The narrowing of the solidification temperature interval and the formation of larger amount of vanadium carbides, as a result of the increase in the vanadium content of the alloy, will favour the appearance of a finer structure. In addition, the phases volume fraction will change, i.e. the primary -phase fraction will decrease and the amount of M 7 C 3 carbide will increase.

The results of studies of the effect of different amounts of the Fe-Ti inoculant on structure and selected mechanical properties of High Chromium Cast Iron (conventionally abbreviated as HCCI) are presented. The main purpose of the inoculation is structure refinement and hence the improvement of casting properties. Generally considered a strong carbide-forming element, titanium is an effective inoculant for the high chromium cast iron. However, there is an optimal amount of titanium addition beyond which the mechanical properties begin to deteriorate. The studies enabled determining the amount of Fe-Ti inoculant optimal for the cast iron of a given chemical composition.

“…These types of microstructures have good wear resistance properties. 2,3) Fe-12$35Cr-C white cast irons are used as hardfacing alloys; these alloys have a high hardness value due to their high M 7 C 3 content. [4][5][6][7] M 7 C 3 is surrounded by austenite, which is relatively soft in comparison to the extremely hard M 7 C 3 .…”

This study investigates the microstructure and wear characteristics of hypoeutectic, eutectic and hypereutectic (Cr,Fe) 23 C 6 carbides in hardfacing alloy cladding by using gas tungsten arc welding (GTAW). Chromium and graphite alloy fillers were used to clad ASTM A36 steel substrates. These coatings were specially designed to vary the size and proportion of the (Cr,Fe) 23 C 6 carbides that are present in the microstructure at room temperature. Depending on the amount of graphite used in the alloy filler, a hypoeutectic, eutectic or hypereutectic microstructure was obtained on the coated surface. The wear behavior indicated that the abrasive wear resistance is not only simply related to the hardness of the deposit but that it is also determined by the carbides and matrix structure of the coating. The hypereutectic carbides have the largest (Cr,Fe) 23 C 6 carbide content and the maximum hardness; however, they show the worst wear resistance due to the large particles were dug out during wearing.
