Abstract
Technical features and examples of the practical use of technology of combined hardening treatment of steel tools are presented, which includes (1) hardening thermal cycling treatment (HTC) of tool blanks and (2) thermo-hydro-chemical treatment (THCT) of the finally manufactured instruments. THCT creates volumetric hardening of tools by thermal cycling with incomplete solid-phase α ↔ γ transformations, followed by quenching and tempering. HTC creates surface hardening of tools by boiling refractory compounds in hydrosols followed by tempering. As a result of combining THCT + HTC, the service life of cutting steel tools increased by 2–20 times, and that of die tools by 1.9–2.1 times compared to traditionally hardened tools.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
