“…Cryotreated alloy shows a lower rate of corrosion than that of tempered and air cooled alloy. Similar improvement in corrosion resistance has been observed by Amini et al in cryotreated tool steel 24) and Vidyarthi et al in destabilized and cryotreated Cr-Mn-Cu white cast iron.…”

“…During subsequent warming up to the room temperature these are acting as preferential sites for further finer carbide nucleation which increases the carbide volume percentage as well as homogeneous distribution. 24,25) Moreover, the increase in the amount of finer secondary carbide precipitates in cryotreatment contributes to the increase in the dispersion strengthening effect. The microhardness values at different tempering time also substantiate these effects as depicted in Table 1.…”

“…There has been a continuing interest to study the effect of cryogenic treatment on particularly die and tool steels and its effect on resulting wear behavior. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] In general, the effect of cryogenic treatment on different types of steels results in an extensive increase in wear resistance. This was attributed to complete transformation of austenite to martensite.…”

The effect of deep cryogenic treatment and air cooling subsequent to sub-critical tempering treatment on the structural evolution and the resulting wear performance of Cr-Mn-Cu white cast iron in sand-water slurry media were studied. The as-cast matrix of Cr-Mn-Cu white cast iron is predominantly austenitic which can be transformed to a martensitic matrix embedded with fine M7C3 carbides, by a sub-critical tempering treatment followed by air cooling. But the retained austenite is not totally converted. Quenching of alloy in liquid nitrogen bath after subcritical tempering enables more amount of transformation of austenite with simultaneous homogeneous precipitation of fine carbides. The phase transformation and corrosionerosion behavior were characterized by optical and scanning electron microscopy, bulk and micro-hardness measurement and x-ray diffraction analysis, measurement of corrosion rate and slurry erosion test. The slurry erosive wear performance has been found to be much better in the cryotreated alloys compared to those with conventional sub-critically tempered alloys.

“…This concept was commonly accepted until newer observations showing that the reduction in the retained austenite content (more complete γ to α′ transformation) also plays an important role in these improvements when the materials are finally low-temperature tempered [3,4,[8][9][10][13][14][15][16][17][18] and that the presence of an enhanced number and volume fraction of SGCs (with a size of several hundreds of nanometres) is the key factor affecting the wear performance [4][5][6][15][16][17][19][20][21]23].…”

“…Mentioned microstructural alterations are reflected in higher as-SZT hardness [1-3, 11, 14, 15], better dimensional stability of components and tools [20,21], and "extra" wear performance [2,3,9,16,22]. e toughness and fracture toughness are, however, worsened [23], except the cases where the steels are high-temperature tempered [24,25].…”

e microstructure, phase constitution, and hardness of Cr-V ledeburitic tool steel Vanadis 6 subjected to subzero treatment at −140°C and for different soaking times have been investigated. e light microscopy, scanning electron microscopy, and X-ray diffraction have been used for microstructural investigations. e hardness has been evaluated by the Vickers method. e obtained results assist to draw that subzero treatment reduces the retained austenite amount and increases the population density of carbides, compared to conventional heat treatment. e extent of decrease in the retained austenite amount makes around 85%, and the increase in population density of small globular carbides was approximately fivefold. High compressive stresses were identified in the retained austenite, and their values follow the increase in carbide count. is makes a serious support to the theory explaining the formation of "extra" carbides as a by-product of more complete martensitic transformation. As a result of the mentioned microstructural changes, the material hardness increased from 875 ± 16 HV 10 up to 954.6 ± 14 HV 10 for conventionally quenched and SZT steels, respectively.
