In the National Research Technology University “Misis” held the fourth international conference “Alloys with the memory of form-2021”. The purpose of the conference is an overview of the areas of modern research and development in the field of alloys with the memory of the form and related phenomena.
Keldysh Center (Roskosmos State Corporation structure) presented their work as part of the section “New materials. Production technologies and the use of alloys with form memory.”
The field of applying alloys with the effect of the memory of the form is very diverse and constantly expanding, first of all, these are aircraft and space technologies, instrument and engineering, medicine, robotics. Developed in the center of Keldysh Center “Materials based on Tinicu alloy, can be used, in particular, to create micromechanical operational devices, such as: micro-actuators, actuators, micropintstes.
In its poster report, the Researcher Irina Záletova told about the study of the process of forming a crystal structure in the electrical processing processing of the TINIcu rapidly damned amorphous alloy. To this end, a sample with heterogeneous crystallization in the longitudinal direction of the tape was investigated. From the data obtained, it can be seen that in case of electrical processing, in the case of insufficient heating, it does not complete the crystallization of the sample, different sections along the tape can have a different degree of crystallization. It is noted that the crystallization of the amorphous phase comes from the surface into the inner part due to the growth of surface columnar crystals, and with an increase in thermal energy due to the formation and growth of grinding from the inside.
Deputy Head of the Department of Nikolai Sitnikov presented a report on the topic: “Investigation of the processes of crystallization of rapidly rolled high-alloy alloys of the TINI TiCu quasi-injection system after large plastic deformations.” The work has studied the effect of intense plastic deformation under conditions of twisting under high pressure on the structural properties of the raised alloys of the TINI-TICU quasi-ticu system with a copper content of 30 to 38 atomic percent. It is shown that the tint of the high pressure of the amorphous alloys of the TINI-TICU system leads to partial nanocrystallization of the amorphous state. The work was completed with the support of the grant by the Russian Scientific Fund.
The center for the use of nanotechnology in the power engineering and power supply of the SPTC Celdysh SPTA space systems at the same time as a center for collective use, which provides access to research and technological equipment to researchers performing developments in the field of nanoindustry Roskosmos as part of the activities of various specialized federal targeted programs. , as well as organizations of other industries.
