Abstract
Antiwear high manganese steel after water-tenacity treatment is mainly heated to after 400~700 DEG C, 20~40min of insulation by a kind of method for improving antiwear high manganese steel hardness, its method under 3~6GPa pressure, and power-off pressurize naturally cools to room temperature.The present invention have the advantages that method be simple and convenient to operate, integral hardness it is uniform and stable；The hardness number of the potassium steel handled by the inventive method is increased substantially, and its hardness number is 484~522HV, and 140%~160% is improved compared with before processing.
Description
Technical field
The invention belongs to field of material technology, more particularly to a kind of processing method of manganese steel.
Background technology
Antiwear high manganese steel has higher intensity and toughness and excellent work hardening ability, thus is used as high-abrasive material
It is widely applied in fields such as mine, metallurgy, railway and electric power.Because the case hardness of potassium steel is relatively low, using just
In the case that phase or shock loading are not high enough, fail to form sufficient drawing hardening effect on its surface, so as to cause larger
Abrasion.In order to improve the service life of potassium steel, using preceding need to potassium steel carry out cure process.At present, potassium steel is hard
Change method mainly includes：The methods such as alloying Metamorphism treatment, surface deformation strengthening, precipitation-hardening and explosion hardening.Using alloy
Change Metamorphism treatment and precipitation-hardening method to improve the hardness of antiwear high manganese steel, it is easy to apply in the industry, but cost it is higher and
Hardening effect is limited.Though can effectively improve the hardness of potassium steel using surface deformation strengthening and explosion hardening method, this is only
It is the case hardness for improving potassium steel, and easily there is uneven phenomenon in case hardness.
The content of the invention
It is an object of the invention to provide a kind of technique it is simple, be easily manipulated and integral hardness it is uniform and stable, can be effectively
The method for improving antiwear high manganese steel hardness.
The method of the present invention is as follows：
Antiwear high manganese steel after water-tenacity treatment is placed on the enterprising horizontal high voltage heat treatment of cubic hinge press, pressure：3~6GPa,
Heating-up temperature：400~700 DEG C, soaking time：20~40min, power-off pressurize naturally cools to room temperature.
Described antiwear high manganese steel, its chemical composition mass percent wt% is：C 0.90~1.30, Mn 11.00~
14.00th, Si.030~0.80, P≤0.10, S≤0.05, its surplus are Fe.
High Manganese Steel of the present invention is single austenite, passes through high voltage driving IC, it is possible to increase the cause of potassium steel
Density, furthermore, potassium steel is internally formed a large amount of deformation twins and dislocation after high voltage driving IC at it, greatly improves in potassium steel
The dislocation density in portion, these highdensity dislocations hinder dislocation motion, harden potassium steel, so as to improve the hardness of potassium steel.
The present invention has the following advantages that compared with prior art：Technique is simple, it is easy to manipulate, and integral hardness is uniform and stable,
On the basis of the primitive component of material is not changed, the hardness of antiwear high manganese steel can be effectively improved, its hardness up to 484~522HV,
140%~160% is improved compared with before processing.
