“…Different aspects concerning behavior of M 7 C 3 carbides in steels were considered recently (Ref [11][12][13][14][15][16][17][18][19][20][21][22]. Stacking faults within iron-chromium carbide of the type (Fe,Cr) 7 was to establish what carbides are formed during 2-h tempering of D3 (or 217H12WF) steel hardened after austenitizing at 1050°C throughout 30 min time.…”

The studies were performed on D3 tool steel hardened after austenitizing at 1050°C during 30 min and tempering at 200-700°C. Based on the diffraction studies performed from the extraction replicas, using electron microscopy, it was found that after 120-min tempering in the consecutive temperatures, the following types of carbides occur:Apart from higher mentioned carbides, there are also big primary carbides and fine secondary M 7 C 3 carbides occurring, which did not dissolve during austenitizing.

“…Carpenter et al [9][10][11] found a large number of crystal defects such as dislocations in the interior of the M 7 C 3 carbide. Chang et al [12] and Coronado et al [13] reported that the abrasion resistance of the hypereutectic Fe-Cr-C alloy was increased with the increase of C and Cr content.…”

The aim of this study was the investigation of the effect of different Y 2 O 3 additives on wear resistance of the hypereutectic Fe-Cr-C hardfacing coatings. The microstructures were observed by optical microscopy, field emission scanning electron microscopy and transmission electron microscopy, respectively. Meanwhile, the hardness was measured and the wear resistance was evaluated. Finally, the role of Y 2 O 3 was discussed. The microstructures of the coatings consist of the primary (Cr, Fe) 7 C 3 carbide and eutectic structure [austenite ? (Cr, Fe) 7 C 3 carbide]. Moreover, Y 2 O 3 can refine the M 7 C 3 carbide and improve the wear resistance of coatings obviously. Y 2 O 3 can absorb at the surface of the M 7 C 3 carbide and improve the wear resistance of the hypereutectic Fe-Cr-C hardfacing coatings.

“…less than that. There are many sources available concerning behaviour of M 7 C 3 carbides in steels [10][11][12][13][14][15][16]. Prolonged low-temperature gas-phase carburization of AISI 316L-type austenitic stainless steel can cause intragranular precipitation of the carbide M 7 C 3 (M: randomly dispersed Fe, Cr, Ni); the effect was observed by Ernst et al [16] .…”

The paper presents the study results on chemical composition of the coarse primary M 7 C 3 carbides occurring in the soft annealed NC11LV/D2 tool steel consisting of: 1.53% C; 11.65% Cr; 0.01% W; 0.81% Mo; 0.068% V; (balance iron plus admixtures), used for cold operation. The microanalyzer of type SEMPROBE Su-30, French made by CAMECA Co., equipped with two WDS X-ray spectrometers and an EDS VOYAGER 3 100, NORAN Instruments Co., made in USA. It was found that out of the three alloying elements occurring in the big carbides of the annealed NC11LV/D2 steel, i.e. Cr, Mo, and V, the chromium appears to be the most uniformly distributed. The big carbides vary concerning C, Cr, Mo, V; the greatest differentiation degree of the contents of Mo and Cr, and the least -of vanadium. The average chemical composition of the big/coarse carbides is as follows: C = 9.42±1.28%; Cr = 44.17±2.95%; Mo = 4.48±3.52%; V = 4.53±0.31%; balance Fe.
