“…Hence, it can be concluded that both cryogenically tempered electrode and workpiece has their respective role to play in enhancing the MRR and their coupled effect results in additional improvement in MRR. The fact that cryogenic tempering of AISI D2 steel increases its hardness is very well documented in published research [11,12,[17][18][19][20][21][22][23][24][25][26]. In present study also, the average hardness value of cryogenically tempered AISI D2 steel was checked and found out to be 63HRC which is 3HRC (5%) more than the untempered sample.…”

“…In present study also, the average hardness value of cryogenically tempered AISI D2 steel was checked and found out to be 63HRC which is 3HRC (5%) more than the untempered sample. The other major change in metallurgy of AISI D2 steel after cryogenic tempering is transformation of relatively soft retained austenite into harder martensite [11,12,[17][18][19][20][21][22][23][24][25][26]. Hence, the improvement in hardness of the cryogenically tempered AISI D2 steel to the untempered ones is attributed to the near absence of retained austenite and more homogeneous distribution of a larger number of finer secondary carbides in the former specimens.…”

“…The temperature of liquid nitrogen at ambient pressure is 77 K. An overview is given in [5]. CT has mainly been used with steels, such as high speed steels, to improve their hardness or wear resistance [6,7]. CT promotes the transformation of the retained austenite into martensite and additionally precipitates very fine carbides.…”

Magnesium alloys have been used in the automotive industry and 3C (computer, communication, and consumer electronics) for many years. Their room temperature properties combined with their low density offer a wide range of applications, especially when processed by High Pressure Die Casting (HPDC). The use of magnesium alloys at higher temperatures is well-studied; special creep resistant alloys containing the rare earth elements silver or yttrium are needed. However, when it comes to very low temperatures, only a few studies have been performed to determine the property-microstructure relationship. The possible fields of application at low temperatures are aerospace and satellite parts and tanks for liquefied gases. This review shall not only examine mechanical properties at low temperatures, but also the permanent effects of cyclic or long-lasting cryogenic treatment on the microstructure and mechanical properties. It was found that cryogenic treatment is able to influence the precipitate concentration and grain orientation in some magnesium alloys. Reduction in the number of brittle phases is improving ductility in some cases. It is well-known that high speed tool steels, in particular, can be influenced by cryogenic treatment. Whether this is possible with magnesium alloys and what the mechanisms are shall be reviewed.

“…Among all of the properties which wear resistance has been reported to be dependent upon, not only type, morphology, amount and distribution pattern of the carbides precipitated from the melt, but the type of matrix structure is also another important research subject. Several authors [6][7][8][9][10] have concluded that the modified microstructure with high nickel and/or chromium content followed by subsequent hardening heat treatment played a significant improvement in wear resistance of white cast iron. However, the high nickel and/or chromium contents of the white iron inevitably makes the price of casting parts relatively high, especially in conjunction with high temperature hardening heat treatment involved in the high chromium irons.…”

This work analyses the wear behavior of a modified white cast iron (MWCI) with moderate chemical composition using 1.77Ni, 1.42Cr, 0.26Mo and 1.59Cu in comparison to a conventional white cast iron (CWCI). The wear test has been carried out for alloys in the as cast condition using a pin-on-disc test in the loads of 80, 100, 120 and 140 N. Microstructural characterization, hardness, frictional coefficient and the total weight loss have been assessed in each alloy. For a low load of 80 N, the total weight loss of MWCI (0.5 mg) is much less than that of CWCI (1.3 mg). The total weight loss has been increased to 2.8 mg for MWCI, while it is still less than that of CWCI (~3.7 mg) with increasing the load to 140 N. Investigation shows that the wear resistance of the specimens is strongly depended on the hardness derived from their microstructures. More plastic deformation and detachment of the tribolayers are observed on the surfaces with a lower hardness. The wear rate of specimens has been increased with increasing the load especially in the specimens with lower hardness. It has been found that the specimen with a higher hardness shows a lower frictional coefficient under the range of applied loading.
