Description
Technical field
The invention belongs to technical field of alloy material, be specifically related to a kind of ferro-manganese-based corrosion-resistant high damping alloy, and relate to the manufacture method of this ferro-manganese-based corrosion-resistant high damping alloy.
Background technology
Along with fast development of modern industry, the power and the speed of various machineries improve constantly, and follow and the also corresponding increase of hazardous noise that is caused by vibration that arrives.Deleterious vibration can cause fatigue of materials, and reduces the working reliability of mechanical part.With the submarine is example, and the propagation of submarine engine vibratory noise and emission not only can be disturbed the works better of navigational instrument, and oneself can be exposed to the other side; Again, be example with the audio/video, the mechanical vibration in the audio/video will be modulated into ground unrest inevitably, the quality and the sound of influence image; And vibration and noise also have a strong impact on the quality of product, the precision of instrument and the work-ing life of mechanical means.
As seen, no matter be to consider from protection people's the physical and mental health and the angle of Working environment, still from industrialized development trend, the technical problem that vibration and noise have become various countries, world today pay attention to day by day and urgently thirsted for solving.
At present, the approach of minimizing and elimination nuisance vibration and noise not only is to adopt rational physical construction design, also depend on the damping capacity that improves material, promptly select material for use with high damping alloy, with the propagation at prevention and reduction vibratory stress peak, thus the generation of elimination and minimizing nuisance vibration and noise.Usually, the method that reduction material or structural vibration are adopted mainly contains following three kinds: the one, and increase quality and improve the inflexible method, design structural part enough huge and firm, to reduce vibration amplitude, though this method can show significant effect, be not suitable for miniaturization, lightweight and high speed; The 2nd, pursue the rational method of structure design, avoid resonant condition with project organization spare cleverly and promptly avoid resonance, but this method only is suitable for the occasion that vibration source is the single vibration frequency; The 3rd, utilize high damping material to make the method for vibration damping, adopt flexible design, that is, make vibration be converted into heat energy and disappear by resilient energy, this method does not increase the quality of member itself and does not reduce the intensity of member, can also play the effect of favorable damping noise reduction simultaneously.
At present, in industries such as space flight and aviation navigation and communications and transportation, high damping alloy particularly anticorrosive high-damping alloy is used for various structural parts more and more.Ferrimanganic base (Fe-Mn) damping alloy such as Fe-15Mn or Fe-17.1Mn because of it has the intensity height, damping capacity is good and cost advantage is used for fields such as space flight and aviation navigation and national defense and military more and more than copper base and Ni-based damping alloy be low etc.But this alloy is restricted to a great extent because of its corrosion resisting property is not ideal enough in special environment for use such as navigation and military affairs.
About the report of damping alloy except aforesaid Fe-Mn base damping alloy, particularly be also shown in the Chinese patent literature all at document, for example application for a patent for invention publication number CN101532114A has disclosed a kind of Fe-Cr-Mo based anticorrosive high-damping alloy, this Fe-Cr-Mo alloy in strain less than 4 * 10
-4The time show damping capacity, and increase, but just reduce after reaching peak value along with the increase of dependent variable along with the increase of dependent variable; Therefore, the Fe-Cr-Mo alloy is mainly used in the less Working environment of vibrational energy, and range of application is restricted.
