Abstract: PURPOSE: A casting aluminum alloy in which CNT is dispersed and a method thereof are provided to minimize the content of CNT by increasing the elastic modulus of a matrix, thereby reducing prime cost. CONSTITUTION: A casting aluminum alloy in which CNT is dispersed is formed by inserting and stirring 1 to 5vol% of CNT, which is coated with oxide, into the molten metal of an Al-Ti-B based alloy. A casting aluminum alloy in which CNT is dispersed has a TiB2 compound formed in the tissue of the casting aluminum alloy and enhances elasticity. Molten metal of the Al-Ti-B based alloy is formed by mixing and stirring an Al-Ti based alloy molten metal and an Al-B based alloy molten metal in an in-situ method. [Reference numerals] (AA) Elastic modulus(GPa); (BB) Elastic modulus increase of a composite material due to CNT distribution; (CC) Elastic modulus increase of a matrix due to TiB2 formation

Abstract: A method of manufacturing a cylinder-liner of a vehicle is provided to reduce the product cost by simplifying the manufacturing process. A method of manufacturing a cylinder-liner of a vehicle comprises the step of making a billet by performing a continuous casting on molten metal containing aluminum as a main component. The molten metal includes silicon of 14 to 25 weight percent, copper of 2 to 7 weight percent and magnesium 0.2 to 2.0 weight percent. The billet is hot-forged in a predetermined range of temperature to form an aluminum liner. The aluminum liner is heat-treated in a predetermined temperature for a predetermined time.
