Abstract
The invention discloses a preparation method of a porous nickel-base superalloy. The preparation method comprises the following steps: 1, preparing a billet according to the proportion of each component; 2, placing the billet for 12 hours under a natural condition, drying at 80 DEG C for 4 hours, and removing a pore forming agent at 130-140 DEG C to obtain a sintered green body; and 3, preserving the heat of the sintered green body for 1 hour at 1200 DEG C in a ZRY55 vacuum hot press sintering furnace to realize sintering forming, thereby obtaining the porous nickel-base superalloy. According to the preparation method of the porous nickel-base superalloy, provided by the invention, an obtained nickel-base superalloy material is good in compressive property and relatively high in compressive strength and shearing modulus.
Description
Technical field
The present invention relates to a kind of preparation method of high temperature alloy, be specifically related to a kind of preparation method of porous Ni-base superalloy.
