| Abstract Scope |
Ceramic particle reinforcements can significantly increase the strength and stiffness of common Al-alloy and have the potential to substitute steel components. In terms of the highest mechanical properties, the powder metallurgical manufacturing route for such aluminum matrix composites (AMC) is superior to the melt metallurgical one. In our study, AlSi1MgMn alloy powder is strengthened with µm-scale SiC reinforcements in fractions between 5 and 15 vol.-% by using high-energy ball-milling (HBEM) and investigated concerning milling time and atmosphere of the HEBM process. These particle-reinforced aluminum powders are further processed into rods by indirect extrusion technology and then subjected to precipitation hardening. The influence of HEBM and heat treatment are studied cross sections and tensile tests on dog bone samples. The results will be compared to a steel rod from a commercial shock absorber. |
