Larger diameter alloy ingots or cakes or press materials need water speed forging hydraulic press forging. Higher degree of alloying, not easily deformed alloy widely used precision casting, such as casting turbine blades and vanes. To reduce or eliminate the stress of cast alloys in the axis perpendicular to the grain boundaries and reduce or eliminate loose, in recent years has developed a directional crystallization process. This process is in the solidification process along a crystal grain growth direction to be no lateral parallel columnar crystal grain boundaries. Achieve directional primary crystallization process conditions and the solid phase in the liquid line between the lines to establish and maintain a sufficiently large axial temperature gradient in the axial direction and a good heat dissipation. In addition, in order to eliminate all grain boundaries, the need to study single crystal blades manufacturing process. Powder metallurgy process, mainly for the production of precipitation strengthening and oxide dispersion strengthened superalloys. This process can not generally get deformed superalloy plasticity even superplasticity. Integrated treatment temperature alloys with alloy is closely related, the organization is controlled by the metal heat treatment. High-temperature alloys generally subject to heat treatment. Typically precipitation hardening type alloy after solution treatment and aging treatment. Solid solution strengthening type alloy after solution treatment only. Some of the alloy in aging twice before to go through an intermediate processing. The first solution treatment is to make the second phase dissolved the alloy matrix, so that the aging treatment at γ, carbide (cobalt-based alloys) strengthening phase homogeneous precipitation, followed in order to obtain a suitable grain size in order to ensure the high temperature creep and lasting performance. Solution treatment temperature is generally 1040 ~ 1220 ℃. The widely used alloys, the aging treatment after more than before 1050 ~ 1100 ℃ intermediate processing. The main role of intermediate processing in the γ grain boundary carbide precipitation and grain boundary films to improve the state of some alloy is also precipitated at the same time some of the larger particles of γ phase precipitated during aging fine γ phase to form a reasonable match. Aging The purpose is to make a supersaturated solid solution uniformly precipitate γ phase or carbides (cobalt-based alloys) to improve high temperature strength, aging treatment temperature is generally 700 ~ 1000 ℃.
