Determination of Modulus of Elasticity in Hypoeutectic Silumin Castings
Keywords:castings, Al-Si alloys, elasticity modules.
The paper presents the results of investigations of elasticity modulus of aluminum alloys castings of various silicon content. The castings solidified in various thermal conditions. It was found that modulus of elasticity depend on microstructure parameters. The results of studies for elasticity modules were presented using different relationships. Computations were made for elasticity modulus of α-phase and eutectic determined in different conditions of solidification process. The results of calculated modulus of elasticity were compared with that taken from the experiment for castings solidify in various conditions.
