Patent ID: 6852428

Claim:
A method for manufacturing laminated heat resistant alloy plate comprising: forming a plurality of striae at a predetermined interval on a Ni alloy plate having a thickness of 0.5 mm to 5.0 mm; superimposing a plate which is made of a material the same as or different from that of this striated plate onto the striated plate so as to cover and striae through a sheet of Ni braze which is amorphous and does not contain organic binder; and setting them at predetermined position so as to face the striae downward, adding a load of 30 g/cm 2 or more on said striated plate uniformly by dividing the load using small blocks which respectively have loading areas of 30 cm 2 and less, heat treating at temperature of 980 to 1020° C. for 5 to 60 minutes, heat treating at temperature of 1050 to 1150° C. for 2 hours or more, and heat treating at temperature of 1100 to 1200° C. which is higher than the temperature of said heat treatment for 2 hours or more for 15 to 60 minutes, in an inert gas atmosphere or a vacuum.
