Behaviour of a quasicrystalline strengthened Al-alloy during compression testing = Verhalten einer quasikristallinen Aluminiumlegierung im Druckversuch
Markoli, Boštjan ; Bončina, Tonica ; Zupanič, Franc
In this work, an Al-Mn-Be-Cu alloy was prepared by vacuum induction melting and casting. The alloy was then remelted and gravitationally cast into cylindrical metallic dies with 2 mm, 4 mm and 8 mm ...diameters in order to obtain the quasicrystalline phase in the aluminium-rich matrix. The samples with height-to-thickness ratio of 3:1 were tested using compression test at room temperature. The deformation rate was 0.001 s - 1. The main objective was to study the behaviour of the alloy during compression tests to obtain information regarding its plastic deformability and fracture. The compression behaviour of 2-mm and 4-mm samples was almost identical. They could be deformed to more than 0.9 true strain without fracture. In the plastic region, true stress of approximately 450 MPa was attained, and almost no hardening was observed. Such behaviour can arise from a microstructure consisting of primary icosahedral quasicrystalline particles and the matrix composed of two-phase eutectic-like structure composed of lamellar icosahedral phase and Al-rich solid solution. The 8-mm sample contained a considerable fraction of crystalline intermetallic compound and much less quasicrystalline phase, fractured at approximately 0.4 true strain, and at the same time, its true strength was approximately lower for 10% than that of 2-mm and 4-mm-samples.
