Martensitic Transformations and Inelastic Properties of TiNi Alloy Undergoing abc Pressing at 300°C
The effect of multi-axis forging (abc pressing) at 300°C on the temperatures of martensitic transformations and inelastic properties (effects of superelasticity and the shape memory) is explored in Ti49.8Ni50.2 (at %) alloy samples. It is found that the temperature of the onset of direct martensitic transformation B2 → R remains virtually the same after abc pressing. This temperature is equal to 63 ± 1°C. At the same time, the temperature of the end of the direct martensitic transformation to the B19′ structure decreases by 41 ± 1°C. The temperatures of the beginning and the end of the reverse martensitic transformation B19′ → B2 decrease by 18 and 13°C, respectively. It is found that, after abc pressing at 300°C, the alloy samples retain inelastic properties, having values (regardless of the given true strain e) comparable with the value of the inelastic properties of the coarse-grained samples. In all samples under study, the maximum value of the reversible inelastic strain reaches ~18% and is observed at 16–24% of the determined plastic torsional strain.
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.
