- Carbon (C) is a very important element that enhances the hardenability of steel sheets, and mainly determines the strength after quenching. It is an element that further lowers the Ac 3 point and promotes a lower quenching temperature. However, if the C content is less than 0.15%, the effect is not sufficient. On the other hand, if the C content exceeds 0.45%, the toughness of the quenched part is significantly reduced. preferable The lower limit of the C content is 0.16% and the upper limit is 0.35%.

- the steel sheet used in the present invention is heated to the austenite temperature range during heating prior to forming to cause austenite transformation, the mechanical properties at room temperature before heating are not important, and the metal before heating is not important.
- the organization is not particularly limited. Therefore, any of a hot-rolled steel sheet, a cold-rolled steel sheet, and a plated steel sheet may be used as the base steel sheet, and the manufacturing method is not particularly limited.
- the plated steel sheet include aluminum-based plated steel sheets (ie, aluminum-plated and aluminum alloy-plated steel sheets) and zinc-based plated steel sheets (ie, zinc-plated and zinc-alloy-plated steel sheets).
- the plated steel sheet may be an electroplated steel sheet or a hot-dip steel sheet. Also, an alloyed hot-dip galvanized steel sheet can be used.
- the base steel sheet In order to perform quenching after forming into a formed member, that is, a hot pressed member, during die cooling during hot pressing, the base steel sheet is first heated to the austenitic temperature range, and the base steel sheet is once converted to the austenite phase. There is a need to. To do so, heat to more than 3 points of Ac and hold at that temperature for more than 1 minute under normal conditions. Although there is no particular upper limit for the holding time, it is desirable to set the upper limit of the holding time to about 10 minutes in consideration of actual production efficiency.
- the cooling rate during hot pressing (in the mold) or after hot pressing (after demolding) is a parameter that plays a very important role in obtaining stable strength and toughness in hot press members. is there.
- the structure after hot pressing be not a completely martensite structure but an automatically tempered martensite structure. is there.
- diffusion transformation up to the Ms point occurs during hot pressing or during the cooling stage after hot pressing. Cool at a rate higher than the critical cooling rate so as not to occur, and cool at a slow cooling rate of 25 to 150 ° C / s in the temperature range from the Ms point to 200 ° C.
- Such cooling causes tempering at the same time as the martensite transformation occurs, so that a martensite structure with less variation in strength and excellent toughness can be obtained.
- the preferred average cooling rate from the Ms point to 200 ° C. is 30 to: 20 ° C./s.
- Examples of the form of forming in the hot press method include bending, drawing, stretch forming, hole expanding, and flange forming. Further, the present invention may be applied to a forming method other than press forming, for example, roll forming, as long as a means for cooling the steel sheet is provided at the same time as or immediately after forming.
- the member manufactured by the hot pressing method described above is a member having a tempered martensite structure with little variation in strength and excellent toughness.
- the strength obtained is the strength of the tempered martensat structure.
- the hardness (Hv) is, in other words, lower than (maximum quenching hardness-10), but is not excessively tempered. It has a maximum quench hardness of at least 100). If the value of Hv is higher than (maximum quenching hardness-10), the toughness decreases, and if it is lower than (maximum quenching hardness-100), the strength decreases.
- Preferred values of Hv are (maximum quenching hardness-20) or less and (maximum quenching hardness-80) or more.
- the “maximum quenching hardness” is the hardness obtained when the material is kept in a salt bath heated to 900 ° C for 10 minutes and then subjected to water cooling treatment.
- steel molds are at room temperature or several tens. Since the temperature is maintained at about C, the steel mold is used to cool the press-formed member during hot press forming. Therefore, it can be seen that the cooling rate can be changed by changing the mold dimensions and changing the heat capacity.
- the cooling rate can also be changed by changing the mold material to a different metal (for example, copper). If the dimensions and material of the mold cannot be changed, the cooling rate can also be changed by using a water-cooled mold and changing the amount of cooling water at that time. You. Even in this case, for example, using a mold in which a groove has been cut in several places in advance, changing the cooling rate by passing water through the groove during pressing, or raising the press machine during press forming, The cooling rate of the press-formed member can also be changed by flowing. Therefore, the following means can be considered to change the cooling rate before and after the Ms point.
- a different metal for example, copper
- a steel sheet having the composition shown in Table 1 (sheet thickness: 1.0 mm) was used as the base steel sheet.
- These steel sheets are slabs produced in the laboratory by hot rolling and cold rolling.
- steel type No. 2 was subjected to hot dip galvanizing (60 g / m 2 of Zn per one side) using a plating simulator, and then alloyed (the Fe content in the plating film was 15% by mass). ).
- the picker hardness was measured (load: 9.8 N, number of measurements: 5).
- a thermocouple was attached to the steel sheet, and the cooling rate after press forming was measured.
- the cooling rate was changed mainly by changing the mold dimensions.
- water was injected between the dies immediately after the steel sheet temperature reached the Ms point to adjust the cooling rate.
- the maximum quench hardness the hardness obtained when the material was kept in a salt bath heated to 900 ° C for 10 minutes and then subjected to water cooling treatment was defined as the maximum quench hardness.
- a cylindrical test piece with a diameter of 3.0 mm and a length of 10 mm (Fig. 2) was cut out, heated to 950 ° C in air at a heating rate of 10 ° C / s, and then heated at a temperature of 5 ° C. After holding for 5 minutes, it was cooled to room temperature at various cooling rates.
- the Ac 3 point and the Ms point were measured by measuring the change in the thermal expansion of the test piece during heating and cooling. Further, the hardness of the test piece obtained was measured by Pickering hardness (load 49N, number of measurements: 5) and the structure was observed, and the critical cooling rate was estimated from the results.
- Test Nos. 1 to 4 which are examples of the present invention, since the average cooling rate from the Ms point to 200 ° C is appropriate, the obtained hardness is lower than (maximum quenching hardness-10), and The maximum quenching hardness is higher than 100).
- Test No. 5 which is a comparative example, cooling was performed at a speed higher than the critical cooling rate, but sufficient hardness was not obtained because the average cooling rate from the Ms point to 200 t was slow.
- Test No. 6 which is also a comparative example, is too hard because the average cooling rate from the Ms point to 200 ° C is too fast.
- “too hard” does not mean that the absolute value of hardness is high, but that it is close to the maximum hardened hardness.
- the steel sheet of test No. 2 which is an example of the present invention, was heated at 900 ° C for 5 minutes in a heating furnace in an air atmosphere, taken out of the heating furnace, and hot-formed in a hat shape [blank size: 1.0 t] X 80 WX 320 L (ram)].
