Microstructural aspects of the dissolution and melting of Al2Cu phase in Al-Si alloys during solution heat treatment
TL;DR: In this paper, the dissolution and melting of Al2Cu phase in solution heat-treated samples of unmodified Al-Si 319.2 alloy solidified at ≈10 °C were studied using optical microscopy, image analysis, electron probe microanalysis (EPMA), and differential scanning calorimetry (DSC).
Journal ArticleDOI
Effect of alloying elements on the segregation and dissolution of CuAl2 phase in Al-Si-Cu 319 alloys
TL;DR: In this paper, the effect of diverse alloying elements on the dissolution of the copper phase (CuAl2) during solution heat treatment was investigated and the first derivate curves were plotted and used to determine the impact of the additives on the precipitation temperature of the aluminum alloy.
Journal ArticleDOI
Observations on the formation of β-Al5FeSi phase in 319 type Al-Si alloys
TL;DR: In this article, the effects of cooling rate, strontium modification and grain refinement on the volume fraction of β-phase formed was seen to increase with the decrease in cooling rate (i.e., increasing distance from the chill) in the untreated alloy.
Journal ArticleDOI
Optimizing the tensile properties of Al–Si–Cu–Mg 319-type alloys: Role of solution heat treatment
TL;DR: In this article, the role of solution heat treatment on the dissolution of copper-containing phases (CuAl2 and Al5Mg8Cu2Si6) in 319-type alloys containing different Mg levels was investigated.
Journal ArticleDOI
Parameters controlling the performance of AA319-type alloys Part II. Impact properties and fractography
TL;DR: In this paper, the authors measured the Charpy impact energy of Al-Si-Cu AA319-type alloys in terms of the total absorbed energy, and showed that strontium-modification enhances the impact properties, so that the Sr-modified AA319 alloy exhibits the highest impact properties compared to the base, and other alloys at any given dendrite arm spacing.
