Description
Technical field
The present invention relates to Mn-Cu damping alloy technologies, specifically, it is related to a kind of Mn-Cu damping alloys additive.
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.The research and industrialization of noiseless alloy, at present throughout iron
Base, copper-based, aluminium base, the alloy system such as titanium-based and magnesium-based.But it is most promising for current comprehensive mechanical performance and damping capacity
Be twin type Mn-Cu damping alloys.
The reason for twin type damping alloy has damping capacity high is the boundary or parent phase of thermoelastic martensitic transformation twin crystal
With the boundary of martensitic phase, the movement under stress causes stress relaxation.It is clear that Mn-Cu based alloys produce geneva
Body is the prerequisite that such alloy has high-damping.The Martensite temperature of such alloy is associated very greatly, for example with the content of Mn
Containing Mn amounts for 90% alloy transformation temperature is 150 degree, that is, when alloy is cooled to below 150 degree, just have substantial amounts of
Twin is generated.As long as thus temperature just has good effectiveness in vibration suppression less than 150 degree.The amount containing Mn is 80% alloy, phase transformation
Temperature is but below 0 degree, thus such alloy is at normal temperatures just without effectiveness in vibration suppression.By after certain heat treatment（Such as 450
Degree 4 hours of insulation）, martensitic transformation temperature also can be only sustained at 90 degree or so.And, measure alloy shortcoming higher very containing Mn
Substantially, in solidification, solidification temperature range is more tolerant is easily caused casting flaw, easily hot-working character difference and cracking.Thus, such as
It is current Mn-Cu that Martensite temperature is improved by effective alloying means in the Mn-Cu alloys that 40-60% is where measured containing Mn
One problem demanding prompt solution of damping alloy.
