Abstract
The present invention relates to preparation process of aluminium alloy, especially a kind of preparation method of high performance heat resistant aluminium alloy, this method specifically includes following steps, step 1, jet deposition: aluminium alloy injection molding generates heat-resisting phase α-Al12(FEV) 3Si；Step 2, addition trace Ti G, increase hardening constituent, inhibit the roughening of matrix and heat-resisting phase, add 3%TiG using generated in-situ method, and dispersion-strengtherning phase amount increases, body and the roughening of heat-resisting precipitated phase；Step 3: being squeezed and spinning deep processing with anti-, effective solution of the present invention tubing cracks problem, and the aluminium alloy high-strength light prepared, office is around high-strength and high ductility performance.
Description
Technical field
The present invention relates to preparation process of aluminium alloy, especially a kind of preparation method of high performance heat resistant aluminium alloy.
Background technique
Some particular components of Modern New weapon also require to remain to protect at relatively high temperatures except material high-strength light is required
High-strength and high ductility performance, such as cruise missile shell are held, heat-resisting hardening constituent is needed in this kind of aluminium alloy, injection molding can make aluminium
Awing cooling velocity reaches and is conducive to force solid solution alloy mist pearl, and generating heat-resisting phase aluminium alloy spray-deposition method can be with
The big size high-performance heat-resisting aluminium alloy shell of the needs such as navaho is prepared, but because of jet deposition preparation process
In, alloy droplet completes final solidification in flight course cooling, deposition, and procedure parameter is more, and related law is difficult to grasp and control
System, the large-scale pipe prepared in the past is mostly scrapped because of crackle, so there is an urgent need to research and develop a kind of system of high performance heat resistant aluminium alloy
Preparation Method.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of preparation method of high performance heat resistant aluminium alloy.
The technical solution of the present invention is as follows: a kind of preparation method of high performance heat resistant aluminium alloy, method includes the following steps:
Step 1, jet deposition: aluminium alloy injection molding generates heat-resisting phase α-Al12(FEV) 3Si；
Step 2, addition trace Ti G, are increased hardening constituent, inhibit the roughening of matrix and heat-resisting phase, added using generated in-situ method
Add 3%TiG, (220) TiG//(220) α-al(311) TiG//(311) α-Al, mismatch 0.05, Al8.5Fel, 4C1.7Si+
TiG: dispersion-strengtherning phase amount increases, body and the roughening of heat-resisting precipitated phase；
Step 3: being squeezed and spinning deep processing with anti-.
The problem the invention has the benefit that effective solution of the present invention tubing cracks, the aluminium alloy lightweight prepared
High-strength, office is around high-strength and high ductility performance.
Specific embodiment
A kind of preparation method of high performance heat resistant aluminium alloy, method includes the following steps:
Step 1, jet deposition: aluminium alloy injection molding generates heat-resisting phase α-Al12(FEV) 3Si；
Step 2, addition trace Ti G, are increased hardening constituent, inhibit the roughening of matrix and heat-resisting phase, added using generated in-situ method
Add 3%TiG, (220) TiG//(220) α-al(311) TiG//(311) α-Al, mismatch 0.05, Al8.5Fel, 4C1.7Si+
TiG: dispersion-strengtherning phase amount increases, body and the roughening of heat-resisting precipitated phase；
Step 3: being squeezed and spinning deep processing with anti-.
The above embodiments and description only illustrate the principle of the present invention and most preferred embodiment, is not departing from this
Under the premise of spirit and range, various changes and improvements may be made to the invention, these changes and improvements both fall within requirement and protect
In the scope of the invention of shield.
