Description

A kind of method for preparing magnetic Fe-Mn-Si base marmem
Technical field
The present invention relates to marmem field, and in particular to a kind of magnetic Fe-Mn-Si base marmem of preparing Method.Compared with the Fe-Mn-Si base marmem of routine, Fe-Mn-Si base marmem prepared by this method possesses magnetic Property and shape memory are difunctional, so as to expand the application field of such alloy, such as magnetic sensor and driver etc..
Background technology
Compared with NiTi base memorial alloy, Fe-Mn-Si base marmem has low cost, and excellent processability The characteristics of energy and weldability, so since the advent of the world is just of great interest.The memory of Fe-Mn-Si base marmem Effect comes from martensite transfor mation and its heating of the austenite of stress-induced face-centred cubic structure during deformation to close-packed hexagonal structure During reverted austenite.It is worthy of note that the austenite of face-centred cubic structure and the martensite of close-packed hexagonal structure are paramagnetic Property, without magnetic.If ferrimanganic silicon-base alloy magnetic can be assigned, then we possess magnetic and shape memory by one kind is obtained The difunctional marmem of effect.In this case, the application of ferrimanganic silicon-base alloy will further expand, such as can For preparing magnetic sensor and driver.Kanada in 1999 etc. is by the method for oxidation on FeMnSiCr memorial alloys surface Form one layer of magnetic Fe3O4Oxide layer, obtain remember with the difunctional ferrimanganic silicon substrate shape of SME and magnetic first Recall alloy（Journal of Magnetism and Magnetic Materials, 1999, 196-197: 349-350）. However, when the FeMnSiCr memorial alloys deformation prepared to this method, magnetic Fe3O4Oxide layer will come off.Todaka etc. is then It is that a series of iron-base marmems with magnetic and memory performance are prepared for using the method for fast melt-quenching, such as FeMnCrNiCoSi strips（Journal of Applied Physics, 91: 7448-7450; Journal of Magnetism and Magnetic Materials, 2003, 254-255: 410-412）, FeCrNiSiMn strips （Journal of Materials Processing Technology, 2007, 181: 217-221）SiFe/FeMnSi is double Layer strip (IEEE Transactions on Magnetics, 2011,47:3184-3187), SiFe/FeMnCrSiB is double Layer strip（IEEE Transactions on Magnetics, 2014, 50: 2501304）.Valeanu etc. also uses melt The method of fast quenching is prepared for magnetic Fe MnSi base marmem strips（Journal of Magnetism and Magnetic Materials, 2008, 320: e164-e167）.It is worthy of note that melt-quenching method is to equipment requirement Height, and strip two-dimensional material can only be obtained, limit to the application of magnetic Fe-Mn-Si base marmem.Therefore, how to use Conventional equipment is current urgent problem to be solved with regard to the magnetic Fe-Mn-Si base marmem that can prepare needles of various sizes.
The content of the invention
It is an object of the invention to provide a kind of method for preparing magnetic Fe-Mn-Si base marmem.
Fe-Mn-Si base marmem mainly contains tri- kinds of elements of Fe, Mn and Si, and comprising Cr, Ni, Ti, Nb, Cu, One or more in Co, V, Mo, Al, C and N element, the weight percent content of each element is in alloy：Mn 12 ~ 32%, Si 4 ~ 7%, Cr 0 ~ 14%, Ni 0 ~ 8%, Ti 0 ~ 1%, Nb 0 ~ 2%, Cu 0 ~ 1%, Co 0 ~ 2%, V 0 ~ 2%, Mo 0 ~ 2%, Al 0 ~ 3%, C 0 ~ 0.2%, N 0 ~ 0.2%, remaining is Fe and inevitable impurity.Obviously, manganese is most heavy in Fe-Mn-Si base marmem One of basic component wanted.It is worth noting that, the vapour pressure of manganese is high, it is caused easily to be waved under vacuum environment Hair.So when carrying out high-temperature process under vacuum conditions, because manganese atom is from a large amount of volatilizations on surface, ferrimanganic silicon-base alloy Surface is substantially less than the poor manganese layer of core by one layer of manganese content is formed.And manganese is austenite former, its reduction will cause Ferritic formation.It is magnetic phase and ferrite is ferromagnetism.Therefore, the present invention just can be obtained by the method for vacuum heat Obtaining surface has one layer of ferritic Fe-Mn-Si base marmem, so as to impart the function of the alloy magnetic.
The specific method that magnetic Fe-Mn-Si base marmem is prepared using vacuum heat is as follows：By mentioned component Fe-Mn-Si base marmem is handled >=30 minutes in the environment of vacuum≤1Pa with 1000 DEG C ~ 1300 DEG C, subsequent air cooling Or oil cooling or water cooling is to room temperature.When heat treatment temperature is less than less than 900 DEG C, Fe-Mn-Si base marmem will have the second phase Separate out, destroy the uniformity of tissue.In addition, heat treatment temperature is higher, the vapour pressure of manganese is also higher, is so more beneficial for vacuum Lower volatilization of the manganese from alloy surface of heat treatment, so as to ensure the ferritic formation in top layer.In order to avoid the second phase precipitation and Be advantageous to the volatilization of manganese, heat treatment temperature of the invention is 1000 DEG C ~ 1300 DEG C.Magnetic ferrimanganic silicon substrate shape prepared by the above method There are one layer of ferrite, and weight percent content≤10% of the manganese in this layer of ferrite in the surface of shape memory alloys.Meanwhile magnetic Average layer thickness >=3 micron of the ferrite lamellae on property Fe-Mn-Si base marmem surface.In order to possess higher magnetic property, Average thickness >=21 micron of the ferrite lamellae on magnetic Fe-Mn-Si base marmem surface.
In order to obtain best ferrite top layer and excellent SME, Fe-Mn-Si base marmem is best In vacuum≤2.0 × 10-1Handled in the environment of Pa；Preferably processing time >=2 hour under vacuum conditions；Preferably in vacuum ring With 1000 DEG C ~ 1250 DEG C processing, subsequent air cooling or oil cooling or water cooling to room temperature under border；With 1250 DEG C preferably under vacuum environment ~ 1300 DEG C of processing, are then air-cooled to room temperature.Patent ZL201410102165.X discloses is changed into Ovshinsky using high temperature ferrite The solid-state phase changes of body prepare the method for exempting to train Fe-Mn-Si base marmem.Therefore, imitated to obtain more preferably shape memory Should, Fe-Mn-Si base marmem is at 1250 DEG C ~ 1300 DEG C preferably at high temperature ferrite monophase field.
The invention has the advantages that：（1）Do not limited by material shape, the Armco magnetic iron of needles of various sizes and shape can be prepared Manganese silicon substrate marmem.（2）Surface ferrite layer is in-situ preparation, therefore very good with basal body binding force, and deformation will not Cause coming off for ferrite lamellae.
