MANUFACTURING METHOD OF ALUMINUM ALLOYS USING SHAPE AND CREATION LOCATION CONTROL FOR STRENGTHENING PHASE

摘要

The present invention relates to a method for manufacturing aluminum alloys and more specifically, to a method for manufacturing aluminum alloys using control of a creation location and the shape of a strengthening phase, which maximizes a coefficient of elasticity of the aluminum alloys by controlling a creation location and the shape of a strengthening phase which is generated by adding alloy elements such as boron and titanium into aluminum, by controlling a cooling speed and a molten metal temperature in an aluminum alloy process. [Reference numerals] (AA) Form a strengthening phase; (S001) Charge pure Al, Al-5B master alloy (850C); (S002) Maintain 30 minutes; (S003) Charge Al-10Ti master alloy (850C); (S004) Maintain for 20 minutes; (S005) Charge Si element; (S006) Maintain for 30 minutes (1000C); (S007) Tap to a mold
