Title: Production of defectless liquid phase sintered alloy
Inventor: OKATO NOBUYOSHI
IPC: B22F3/10
Filed: 1992-05-14
Abstract: PURPOSE:To provide the sintered body free from shrinkage cavities by bringing a heat supplying body into contact with a part of a body to be sintered, thereby supplying heat to this part. CONSTITUTION:The body 3 to be sintered is inserted into a furnace core tube 2 installed in a heating furnace 1 and is sintered while the body 3 to be sintered is moved by using a push rod 4. The push rod 4 is used as the heat supplying body and is brought into contact with a part of the body 3 to be sintered to supply the heat to this part, by which the final solidification position of the liquid phase is controlled. The sintered alloy is formed of a tungsten alloy contg. 90-98wt.% tungsten, nickel and iron. The contact part of the push rod 4 with the body 3 to be sintered consists of refractories which do not react with the tungsten alloy and the contact part covers >=50% of the area inclusive of the central part at the rear end face of the body to be sintered. As a result, a high yield is embodied without impairing the toughness of the alloy.
