Abstract
The invention discloses a manufacturing method of a sword body. Alloy adopted by the sword body comprises the following chemical components in percentage by weight: 1.2%-1.4% of C, 0.5%-0.7% of Si, 0.10%-0.20% of Mn, 23.0%-24.0% of Cr, 0.3%-0.5% of Ni, 0.30%-0.50% of Ca, 0.15%-0.25% of Mo, 0.2%-0.4% of V, 0.4%-0.6% of nano-diamond and the balance of Fe and not more than 0.1% of impurities. The manufactured sword body is hard to rust and corrode and better in elastic bending ability and hardness.
Description
Technical field
The invention belongs to field of metallurgy, in particular to a kind of sword body making method.
Background technology
In very long social development process, the medium carbon steel of employing substantially of traditional sword body or high carbon steel make, and the double-edged sword of production gets rusty easily corrosion in the process used and preserve.There is such problem too in the manual exactly folding riffled iron forged.Double-edged sword is in this process of use collection, and the often sword body of meeting because playing or go to touch with hand double-edged sword, sweat on hand easily makes double-edged sword get rusty.Simultaneously in use run into plum rain season and wet weather easily causes sword surface oxidisation.In addition, existing double-edged sword has an obvious feature, is exactly that its bending resistance is often lower when its hardness is very high; And when its flexural strength is very high, its hardness is lower again.How can improve hardness and the bending resistance of double-edged sword simultaneously, double-edged sword can be prevented again to be subject to the impact of human factor and natural climate and to cause the quality problems such as damage of getting rusty, be those skilled in the art's technical problems urgently to be resolved hurrily.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of double-edged sword simultaneously having high bending strength and high rigidity, the double-edged sword making method of not easily corrosion again.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of sword body making method, it is characterized in that the chemical composition of the following degree of alloy tool that sword body adopts: C 1.2-1.4%, Si 0.5-0.7%, Mn 0.10-0.20%, Cr 23.0-24.0%, Ni 0.3-0.5%, Ca 0.30-0.50%, Mo 0.15-0.25%, V 0.2-0.4%, Nano diamond 0.4-0.6%, all the other are the impurity that the Fe of surplus and total composition are no more than 0.1%.
The alloy of above-mentioned chemical composition makes double-edged sword not easily corrosion, and has good sharpness, elasticity camber and hardness.
As preferably, the formula of alloy is C 1.25-1.35%, Si 0.55-0.65%, Mn 0.12-0.17%, Cr 23.5-24.0%, Ni 0.35-0.45%, Ca 0.35-0.45%, Mo 0.18-0.22%, V 0.25-0.35%, Nano diamond 0.45-0.55%, all the other are the impurity that the Fe of surplus and total composition are no more than 0.1%.
As preferably, described Nano diamond refers to that median size is between 200-500nm, preferably between the diamond particle of 300-400 nanometer.
The present invention also relates to the making method of above-mentioned sword body on the other hand, it is characterized in that: comprise the following steps:
A. select the alloy of above formula as raw steel;
B. raw steel is heated to 1100-1300 DEG C, carries out forging or roll extrusion formation steel plate;
C. steel plate is heated to 900-1100 DEG C to forge;
D. carry out quenching, thermal treatment and polishing, namely form the sword body needing proterties.
According to technical scheme of the present invention, obtain one one kinds of unsuitable corrosions, intensity is high, good toughness, hardness are high double-edged sword; Produced not easily corrosion, and sharpness, elasticity camber, hardness are more excellent, have the sword of natural figure obvious and attractive in appearance simultaneously.
Embodiment
Below the present invention is described in further detail:
embodiment:
A making method for sword body, the formula selecting alloy is C 1.25-1.35%, Si 0.55-0.65%, Mn 0.12-0.17%, Cr 23.5-24.0%, Ni 0.35-0.45%, Ca 0.35-0.45%, Mo 0.18-0.22%, V 0.25-0.35%, Nano diamond 0.45-0.55%, all the other are that the Fe of surplus and total composition are no more than the alloy of the impurity of 0.1% as raw steel, Nano diamond median size is between 300-400nm
A. raw steel is heated to 1100-1300 DEG C, carries out forging or roll extrusion formation steel plate;
B. steel plate is heated to 900-1100 DEG C to forge;
C. carry out quenching, thermal treatment and polishing, namely form the sword body needing proterties.
Above-mentioned Rockwell Hardness experimental technique is: adopt the hardness that 150Kg load and diamond cone injector are tried to achieve, sword body carries out above-mentioned Rockwell Hardness experiment, and result is 53.Carry out flexural strength detection to product, detected result display intensity value is 2800-2900MPa.
Above-mentioned antirust experimental technique is: it is 85% that the sword body made by aforesaid method and puts into humidity common carbon steel double-edged sword body simultaneously, temperature is in the room of 40 DEG C, after two sword bodies being taken out after 7 days, observe its appearance change, sword body of the present invention is without considerable change, and plain carbon stool double-edged sword can see obvious rust staining.
As can be seen here, the sword body that the present invention makes not easily corrosion, and elasticity camber, hardness are more excellent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
