Abstract:
The study is devoted to the effect cryoprocessing has on the stabilization of VK6 (hard alloy) after irradiation with fast electrons with energy of 5 MeV. To investigate samples with a close microstructure characteristics, a measurement of a structure-sensitive property -- co-effective force -- was held. It was shown that the treatment of VK6 hard alloy with fast electron irradiation increases its microhardness by 30 % in comparison with the original samples without any irradiation. It was found out that the microhardness of VK6 hard alloy samples after treatment with fast electrons depends on

Abstract:
The hyper productive surface plastic deformation processing technology called as wide burnishing (WB) was developed in Russian Federation. The mechanics of new WB technology is different from the classic SPD technologies (rolling or burnishing). For example applied force during processing of burnishing is 150-300 N, of WB is 2500-5000 N due to condition of process implementation in mass production with limited processing time (3-4 turnovers of workpiece). WB also has a high degree of deformation due to a multiple deformation passes. The purpose of the study was to determine the durability of a

The influence of hard lubrication on the processes of diamond grinding (DG) and diamond spark grinding (DSG) of hard-working materials - hard alloy VK6, titanium alloy VT22 and heat-resistant stainless steel 10H11N23T3MP was studied. The conditions of the performed experimental researches are described. The evaluation was performed according to the parameters of the surface roughness parameter Ra of the postcontact temperature Tpk. It was found that the use of solid lubricants (SL) based on stearic acid (65%) and molybdenum disulfide (35%) reduces 1.4… 2.1 times post-contact temperature and ro

It is shown that the structural organization and properties of hard alloys VK6, VK8, VK10 upon radiation treatment with a power density of 175 MW/m2 are determined by state of the zones which are formed around carbide inclusions due to the various kinds of stresses appearance at the “carbide-bond” composition boundaries, including thermostrictive and phase stresses.

This is a template and guidance for how to write letters in high poetic Hebrew. Perhaps it is a page from a bigger collection of samples of letters. Such a book was in some places called an ʾIgron (from ʾiggeret, a letter). Although this is only a template, which has never been sent, it is an important historical source, because it is based on a real letter (or letters). The original letter on which at least part of this text was based was sent to the community of Cairo, as it says in f1/13: “the community of Cairo, that he who dwells in heaven may save them.” Another clue that the original le
