にも制約を受ける。-Titanium clad steel produced by explosive crimping is widely used as a material for chemical equipment. On the other hand, there are restrictions on the size of titanium clad steel due to restrictions on the amount of explosives due to equipment capacity and pollution, and restrictions on the size of titanium plates currently supplied on the market.

The manufacturing method in which molybdenum, platinum, gold, silver, etc. is sandwiched and explosively crimped and then rolled has excellent bonding properties with the base material, but insufficient bonding properties with titanium.

or adhesion when iron powder 4 is interposed between titanium powder 1 and steel plate 3 in order to minimize the influence of intermetallic compounds at the interface between titanium and steel plate. As a result of our research, we found that the particle size of the powder, the pressure applied during hot pressing, and the heating temperature during hot pressing sintering have a significant effect on adhesive properties. That is, if the particle size distribution of the powder is coarse, sufficient airtightness cannot be obtained, and as a result of experiments, 325 mesh or less is good. Next, the hot pressure is 586kvf/c
m2 or more is safe. It was also found that the temperature during hot pressure sintering is preferably α-range heating conditions for the powder. Especially when considering the anisotropy of the material, the heating temperature is -
50°C is optimal. When the β-transform temperature of titanium is 890° C. or higher, the crystal transforms from a close-packed hexagonal system to a body-centered cubic system, and the crystal grains become coarse. Therefore, the heating temperature is preferably α range heating conditions as described above.
