Description
Technical field
The present invention relates to technical field of alloy, specifically, it is related to a kind of high damping alloy.
Background technology
The development of modern industry is maked rapid progress, and the value volume and range of product of all kinds of machineries is all towards high-power and high speed direction hair
Exhibition.But the vibration and noise problem that machinery is produced in the process of running are increasingly protruded, and cause the extensive of association area
Concern.Vibration and noise can not only reduce the service life of equipment, can also carry out noise pollution to ecological environment, serious infringement
The physical and mental health of the people.In traffic, the energy, the field such as communication and electric power, control vibration and reduction noise have become and urgently solve
Engineering problem certainly.The improvement of mechanicalness noise is not only the urgent task in labour protection and environmental protection work, is also to improve
The important solutions of mechanical product quality.
The solution such as traditional sound insulation and sound absorption, increases space and the weight of equipment.The latest development of vibration and noise reducing becomes
Gesture is started with source.The part use of vibration and noise will be produced can be absorbed vibration and the energy of vibration is converted into heat energy
Material is made, it is possible to by mechanical vibration control after just producing, reach the effect of vibration and noise reducing.Quickly grow in recent years
High damping alloy is exactly this kind of material that can absorb vibrational energy.Common high damping alloy has the high-damping of iron-based according to classification
Alloy, it is Fe-Cr-Al systems, Fe-Mn systems and Fe-Si-Al systems etc. to represent type；Aluminium base high damping alloy, represents class
Type is Al-Zn systems, Al-Mg systems and Al-Si systems etc.；Manganese base high-damping alloy, the system that represents is Mn-Cu, Mn-Fe and
The systems such as Mn-Ni.Wherein, intensity highest, be suitable as load load member is iron-based high damping alloy.Building is disliked in environment
Slightly ocean petrochina platform, can undergo various load that can cause Platform Vibration and destroy, and such as wave, wind-force and ice are carried.
In order to reduce platform dynamic load, platform life span and reliability are improved.Plant equipment on platform can produce punching to platform in the running
Hit and vibrate, reduce the reliability of platform.It is before very having reality that iron-based high damping alloy is applied into ocean platform construction
A kind of method on way can not only reduce wave, and wind-force and ice carry the vibration for causing, improves ocean platform job stability,
High damping alloy can be applied to the equipment part on platform, for the raising of equipment resistance to shock.It is contemplated that with me
The further raising of state's industrialization degree, and the growth to vibration and noise reducing requirement, iron-based high damping alloy application Yu Haiyang are put down
Platform construction can obtain huge social and economic benefit.
Iron-based high damping alloy is closed the characteristics of cheap because with high intensity, damping property is superior in various vibration dampings
Come out top in golden series but Fe-Cr-Al and Fe-Si-Al systems in iron-based high damping alloy, produced by ferromagnetic domain
Damping, uses under annealed state, and the mechanical property of material only has the level of mild steel, and yield strength only has 250MPa, much
May not apply to the structural member of ocean platform.The high damping alloy of Fe-Mn systems is moved by the geneva body interface produced after quenching
Movable property gives birth to damping, carries out effective vibration and noise reducing, and mechanical property has reached the level of mild steel, but decay resistance is too
Difference.It is easy to produce electrochemical corrosion to be used so as to reduce the security and platform of ocean platform under the high corrosion environment of ocean
Life-span.Therefore, additive during a kind of alloy smelting for Fe-Mn is developed, the effect of the additive has except that can make product
Outside the mechanical property and damping capacity of existing alloy, it is also possible that Fe-Mn alloys have outstanding corrosion resistance, Ke Yiguang
It is general to be applied to marine environment and other extreme environments.
