Graphene nanosheet (GNS)/ Al2O3 composite powder with homogeneously distributed GNSs has been fabricated from wet ball milled expanded graphite and Al2O3, and then followed by the rotary evaporator at relatively low temperature to dry the mixture and the residual solvent was removed in atmosphere-vacuum pipe-type furnace accessing mixed gases of Argon and Hydrogen at 600 for 6h. During the process, homogeneously dispersed and mixed GNS/ Al2O3 composite powders with quite few damage of GNSs structure and properties have been obtained. The microstructures and grain sizes of GNS/ Al2O3 composite powders have been investigated. The results showed that the addition of GNSs had diminished the size of Al2O3 particles and also the as-prepared GNSs/ Al2O3 composite powders can be dispersed and mixed more homogeneously remarkably with the presence of GNSs.

<p class="AMSmaintext"><span lang="EN-US">The new method for hardening ready-made steels, hard alloys and diamond tools is developed: low-temperature process for producing thin-film solid lubricant coatings by hydro chemical treatment in specially prepared aqueous media of nanosized hard refractory compounds and subsequent tempering. The main advantages of the method over known processes are presented. The principles for dispersion of refractory materials are formulated. The structure and properties of the obtained coatings are examined. <br /></span></p>

Studies of dilatometry, DSC, hardness and XRD have shown that a low temperature cryogenic treatment immediately after supersaturation affects changes of structure and properties taking place during ageing after supersaturation. The third peak visible on DSC diagrams for samples conventially treated disappears on DSC diagrams for deep cryogenically treated samples, and the intensity of the two first peaks on DSC diagrams of deep cryogenically treated samples is a few times lower than on diagrams for conventionally treated samples. The dissolution process for precipitation of Al2Cu in conventionally treated samples progresses faster. Hardness of samples aged after a deep cryogenic treatment within the range of 175-220 oC for more than 60 minutes was higher than of those conventionally treated; at higher ageing temperatures (275-350 °C) the differences in hardness were smaller.
