The Effect of the Solution Annealing Temperature in the Hardening Process on the Properties of Al-Si-Cu Alloys

Tomáš Vlach ORCID..., Jaromír Cais ORCID..., Filip Mamoń ORCID..., Jakub Mareš ORCID...

This article deals with the influence of the applied solution annealing temperatures in the precipita-tion hardening process on the resulting increase in the mechanical properties of Al-Si-Cu alloy cast-ings with different copper contents in the alloy. AlSi7Cu2 and AlSi7Cu4 alloys were cast by gravity casting in a metal molds. Each of the samples was subjected to the Vickers microhardness measure-ment of a solid solution of α(Al) and Brinnel hardness measurement. Microscopic analysis and evalu-ation of the internal structure of each alloy was carried out in relation to used solution-annealing temperature.
