Erratum to: Effect of Tempering on the Structure and Coercive Force in the AISI D3 (217H12WF) Ledeburite Chromium Steel

Abstract

The main purpose of the studies was to establish the effect of the tempering temperature on the changes of carbide and retained austenite contents. It has been found that the course of changes of the coercive force of hardened steel after austenitizing is qualitatively similar to the hardness changes. That means in practice it is possible to determine the 217H12WF steel hardness based on the measurement of the coercive force.

Transformations of Carbides During Tempering of D3 Tool Steel

“…Method of heat treatment, microscopic studies on an optical microscope, the studies of hardness and determination of retained austenite contents by a magnetic method, and carbides by electrolytic extraction method were given in previous publications (Ref [9][10][11][12][13][14].…”

“…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.…”

Fluctuations in Chemical Composition of M7C3 Carbides in the Soft Annealed Nc11lv/D2 Steel

“…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] .…”

Effect of High-Temperature Heating on Chemical Changes in M₇C₃ Carbides of AISI D2 Tool Steel

“…Sato et al [3,4], Głowacki [5,6], Kowalski [7], and with the additives of tungsten, molybdenum and vanadium by Gulajev and Sanczyk [8], Kałuża [9], Nykiel [10], Hryniewicz and Nykiel [11,12], Nykiel and Hryniewicz [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30], Haberling and Schruff [31], Grman et al [32]. It results from the works that the chromium contents in M 7 C 3 carbides occurring in the mentioned steels under annealed state are in the range of about 43 % [3,4] up to 52 % [5,6].…”
