  2. 6. Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperature

    Author : Mohammadreza Zamani; Anders Jarfors; Sten Johansson; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; elevated temperature; microstructural scale effect; Sr modification;

    Abstract : Aluminium alloys with Si as the major alloying element form a class of material providing the most significant part of all casting manufactured materials. These alloys have a wide range of applications in the automotive and aerospace industries due to an excellent combination of castability and mechanical properties, as well as good corrosion resistance and wear resistivity.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloys; cast Al-Si alloys; conversion coating treatment; cerium; localized deposition; surface pre-treatments; microstructure; SEM; FIB-SEM; AFM-SKPFM; aluminiumlegeringar; gjutna Al-Si legeringar; omvandlingsbeläggningar; cerium; lokaliserad deposition; ytförbehandlingar; microstruktur SEM; FIB-SEM; AFM-SKPFM;

    Abstract : The formation of conversion coatings based on Ce, trivalent Cr and Ti/Zr is triggered by the local pH increase at cathodic IM sites of the aluminium alloy microstructure. The pH gradient is created over the cathodic intermetallic (IM) sites of the microstructure and its intensity is influenced by their activity which depends on their chemical composition, their size, and spatial distribution.
