Effect of dispersion hardening on impact resistance of EN AC-AlSi12Cu2Fe silumin
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
Development of modern technology have generated supply of better and better, more resistant structural materials not attainable earlier. Weight of metal structures is of a great importance, and as a consequence, also weight of materials used for a given structure. More often, for metal structures are used lightweight metals and their alloys, from which aluminum and its alloys have become the most widespread. These alloys, based on Al-Si equilibrium system, contain additional constituents (e.g.: Mg, Cu) enabling, except modification, improvement of mechanical properties obtained in result of heat treatment. The paper presents an effect of modification process and heat treatment on impact resistance of EN AC-AlSi12Cu2Fe alloy. Solutioning and ageing temperatures were selected on base of registered curves of the ATD method. For the neareutectic EN AC-AlSi12Cu2Fe silumin one obtained growth of the impact resistance both due to performed modification treatment and performed heat treatments of the alloy.
