Fe-Mn 基阻尼合金的马氏体相变与阻尼性能 Title: The Martensitic Phase Transformation and Damping Properties of Fe-Mn Based Damping Alloys Abstract: Fe-Mn based damping alloys exhibit excellent mechanical properties, especially in terms of their damping capabilities. This paper aims to investigate the martensitic phase transformation mechanism and explore the relationship between the martensite transformation and the damping properties in Fe-Mn based damping alloys. The study reveals the potential applications of these alloys in various engineering fields due to their outstanding damping performance. 1. Introduction 1.1 Motivation The demand for materials with improved mechanical properties has been steadily increasing in fields such as construction, transportation, and energy. Damping alloys play avital role in reducing structural vibrations, thus preventing fatigue and increasing overall system performance. Among these alloys, Fe-Mn based damping alloys have gained significant attention due to their excellent damping properties. 1.2 Objective This study aims to provide an in-depth understanding of the martensitic phase transformation mechanism and its correlation with the damping properties of Fe-Mn based damping alloys. The relationship between the composition, microstructure, and damping behavior will be analyzed. 2. Martensitic Phase Transformation in Fe-Mn Based Damping Alloys 2.1 Martensitic Transformation Martensitic transformation is adiffusionless phase change that occurs in certain alloys. It involves acrystal structure change from austenite to martensite, leading to unique mechanical properties. In Fe-Mn based damping alloys, the martensitic transformation is responsible for exceptional damping characteristics.
