Caracterización de aleaciones aluminio-cobre para aplicaciones en partes y piezas automotrices.

Abstract

The purpose of this degree work is to characterize aluminum-copper alloys employing destructive test and a statistical analysis that allows generating a database with the main mechanical properties of the combinations and can be used in the creation of new materials in the libraries of computer-aided design programs used for the manufacture of automotive pieces and components The specimens with different aluminum-copper (Al-Cu) alloys were obtained by melting in a fixed. Crucible and permanent mold furnace. The different compositions of the specimens are achieved by varying the load of the materials in the oven, therefore obtaining Al-Cu combinations from 99% aluminum, 1% copper to 95% aluminum, and 5% copper, successively between the five specimens. Each of the specimens must comply with the geometry established in ASTM E8/E8M-13 for tensile tests, which were manufactured using a conventional volume. Finally, a statistical analysis of the data obtained was performed, after the mechanical properties necessary to generate the databases of each resulting alloy were calculated. Therefore, it was concluded that the percentage of copper increases the mechanical strength of the aluminum-copper alloy, and it is recommended to use the databases in design or simulation software for the manufacture of automotive pieces and components.
