摘要

摘要：研究了经β区退火后（α + β）区淬火的VT16合金试样的组织特征和热力学行为。为达到形状记忆效果，将试件的残余变形量调整为2.2 ~ 3.8%。结果表明，在45 ~ 250℃的温度范围内加热，由于马氏体相变，试样的形状部分恢复（1.1 ~ 0.8%），当温度超过270℃时，由于β相的扩散分解，变形逐渐积累。

Characteristics of Shape Memory Effect in Commercial Titanium Alloy VT16

Abstract—The structural features and thermomechanical behavior of VT16 alloy specimens subjected to annealing in the β-region followed by quenching from the (α + β)-region are investigated. To achieve the shape memory effect, the test specimens were upset by the amount of residual deformation from 2.2 to 3.8%. It was found that when specimens are heated in the temperature range from 45 to 250°C, a partial shape recovery (from 1.1 to 0.8%) occurs due to reverse martensitic transformation and when the temperatures exceeds 270°C, deformation accumulates due to the diffusive decomposition of the β phase.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
