Abstract

The method of electron-microscopic analysis investigated the structure of the alloy Ti-50.2 at % Ni at different stages of dissolution; low-temperature thermomechanical treatment (LTTT), post-deformation edgy (PDE), and recrystallization. The microstructure of B2-austenite, which is formed in the process of incoordination, was also investigated, including in the conditions of isothermic burning of the original recrystallized structure.

Highlights

The alloy Ti-50.2 at.%Ni of general technical purpose, widely used for actuators, is weak and occupies an intermediate position in the nickel content between the ecvitom and aging alloy of medical use studied in work
According to well-known data, aging in titanium nickel content with a nickel content of less than 50.5% does not go; there is reason to believe that when exposed in the interval of temperatures 400-450° C, it to some extent develops [1-3]
НЗС - elements of nanograined structure; НСС - elements of nanosubgrain substructure Under the conditions of post-deformation annealing at a temperature of 430 ° C, the processes of pre-separation at the zone stage and softening and nanocrystallization of the amorphous component of the austenite structure, proceed simultaneously

Summary

Introduction

The alloy Ti-50.2 at.%Ni of general technical purpose, widely used for actuators, is weak and occupies an intermediate position in the nickel content between the ecvitom and aging alloy of medical use studied in work. According to well-known data, aging in titanium nickel content with a nickel content of less than 50.5% does not go; there is reason to believe that when exposed in the interval of temperatures 400-450° C, it to some extent develops [1-3]. There is no data on the effect of burn-off on the calorimetric effects of martensite transformations in the original crystallized structure
