(Industrial Application Field) The present invention relates to a method for heat treating titanium clad materials. Titanium clad materials are made of titanium or titanium alloy (hereinafter simply referred to as titanium), and are made of steel, aluminum, copper, nickel, chromium, or their alloys, as well as plates, tubes, and rods made of materials cheaper than titanium. , metal materials such as mold materials. (Prior art) Bonded parts of titanium clad materials tend to peel off when heat treated, and in many cases finishing heat treatment is not performed, so it is not possible to improve material properties that have changed due to processing by heat treatment. I was in a situation I couldn't hope for. (Object of the Invention) An object of the present invention is to provide a method for heat treating a titanium clad material in which the bonded portion does not peel off during finishing heat treatment. (Structure and operation of the invention) The present invention is structured as follows. (1) Titanium or titanium alloy is degassed and softened in an atmosphere that excludes hydrogen and hydrogen compounds.
A method for heat treatment of a titanium clad material, characterized in that after the titanium clad material is brought into contact with the base material by rolling, a finishing heat treatment is performed at a pressure not lower than the degassing and softening heat treatment. (2) After degassing and softening titanium or titanium alloy under reduced pressure in an atmosphere excluding hydrogen and hydrogen compounds, and adhering it to the base material by rolling, finishing heat treatment is performed at a pressure not lower than the degassing and softening heat treatment. A heat treatment method for titanium clad materials characterized by: (3) Titanium or titanium alloy and base metal steel are subjected to degassing softening heat treatment under reduced pressure in an atmosphere excluding hydrogen and hydride compounds, and then, after bonding titanium or titanium alloy and base metal by rolling, finishing heat treatment is performed. A titanium cladding characterized in that the degassing softening heat treatment is performed at a pressure that is not low, and the following relational expression is satisfied between the finishing heat treatment temperature (T 2 ) and the degassing softening heat treatment temperature (T 1 ). Heat treatment method for materials. T 2 ≦T 1 +100, but 400≦T 1 ＜700 (℃) T 2
≦800, but T 1 ≧700 (℃) The present inventors found that when titanium clad material is subjected to finishing heat treatment, the unbonded area expands, and this tendency is observed when the titanium is not degassed and softened before rolling, or when the titanium is heated It has been found that this effect is significant when the atmosphere contains hydrogen or hydrogen compounds, or when the furnace pressure for finishing heat treatment is lower than that for degassing softening heat treatment. They also discovered that hydrogen is involved in the expansion of unbonded areas, and that dehydrogenation treatment is important to prevent this. To degas and soften titanium, it is heated to 40-1000°C in an atmosphere excluding hydrogen and hydrogen compounds. Hydrogen starts to be released significantly from around 200°C, but it is desirable to heat it to 400°C or higher to soften titanium. The upper limit heating temperature is not particularly limited, but if it exceeds 1000°C, the titanium crystal grains will become coarser, which is not preferable. If a heating furnace burns petroleum or gas for direct heating, hydrogen in the combustion gas will enter the titanium, so indirect heating or other heating methods must be used. In the case of reducing the pressure inside the furnace, a known vacuum heating furnace can be used. If titanium or the base material is subjected to degassing heat treatment, there will be very little gas released at higher pressures. Similarly, gas release is extremely small at temperatures lower than the heating temperature for degassing softening heat treatment, but if degassing softening heat treatment is performed under reduced pressure and the furnace pressure for finishing heat treatment is higher than this, as shown in Figure 3. There is a range in which the finishing heat treatment temperature after bonding can be higher than the degassing softening heat treatment before bonding. (Example) Table 1 shows the experimental conditions, and Figures 1 to 3 show the experimental results and the relationship between the heat treatment temperature before and after rolling bonding and the unbonded area ratio (=unbonded area/board area x 100%). Ta. Here, if the unbonded area ratio is 2% or less, the bonding is good. The marks in the figure are shown in Figure 1. Figure 1 shows the case where the pressure inside the heat treatment furnace is atmospheric pressure both before and after bonding, and the bond is good within the range of the following relationship between the heat treatment temperature after bonding (T 2 ) and the heat treatment temperature before bonding (T 1 ). be. That is, T 2 ≦T 1 /2 + 350 (℃) However, 400≦T 1 ≦900
(℃) Figure 2 shows the case where the pressure inside the heat treatment furnace was atmospheric pressure before bonding, and 10 -2 Torr after bonding. At this time, the relational expression between T 1 and T 2 for good adhesion is as follows. T 2 ≦T 1 ／3＋300 (℃) However, 400≦T 1 ≦900
(℃) Figure 3 shows that the pressure inside the heat treatment furnace is
The pressure is reduced to 10 -2 Torr, and the pressure is atmospheric after bonding. At this time, the relational expression between T 1 and T 2 for good adhesion is as follows. T 2 ≦T 1 +100 (℃) However, 400≦T 1 ＜700
(℃) T 2 ≦800 (℃) However, T 1 ≧700 (℃) In other words, the heat treatment temperature range for good adhesion is the second
Figure 3 is the narrowest and Figure 3 is the widest.
