“…The microhardness measured by CSM microhardness tester is Hv 810, which is close to the reported values of annealed Al 65 Cu 20 Fe 15 QC (Hv 844) and Al 64 Cu 22.5 Fe 13.5 QC (Hv 804) [36]. Microhardness, together with elastic modulus, is also provided by nanoindentation tests.…”

The potential applications of quasicrystals (QCs) in automotive and aerospace industries requires the investigation of their fracture and failure mechanisms under dynamic loading conditions. In this study, Al–Cr–Fe powders were consolidated into pellets using spark plasma sintering at 800 °C for 30 min. The microhardness and dynamic failure properties of the samples were determined using nanoindentation and split-Hopkinson pressure bar technique, respectively. Scanning electron microscopy and transmission electron microscopy were employed to analyze fracture particles. The dynamic failure strength obtained from the tests is 653 ± 40 MPa. The dynamic failure process is dominated by transgranular fracture mechanisms. The difficulty in the metadislocation motion in the dynamic loading leads to the high brittleness of the spark plasma sintered (SPSed) Al–Cr–Fe materials.

The Al65Cu20Fe15 alloy has been prepared by conventional casting to the mould and by melt spinning or atomisation techniques. The melt spun ribbon was in the form of fragmented, brittle akes, atomized powder has spherical shape with average size 17.2 µm. It was found that icosahedral I-phase was the main phase in all types of prepared samples. In the conventionally cast alloy the following phases have been identied additionally: λ-Al13Fe4, τ -AlCu(Fe) and η2-AlCu. In the melt-spun ribbon the formation of η2 is avoided, while in the atomised powder the I-phase coexists with small amount of copper rich τ -phase. In the cast ingot the I-phase form as a product of peritectic reaction λ + L, while in the ribbon and in the powder quasicrystal solidied from the undercooled melt as primary phase and next metastable cubic τ -AlCu(Fe) was formed at the interdendritic areas. Single I-phase grains of the sizes about 1 µm are observed in the ribbon close to the wheel side.

“…Therefore, many of the questions that researchers have proposed in material investigation have to do with which proportion of elements should be mixed in order to obtain materials with the desired mechanical, physical and chemical properties (Suárez et al, 2011;Tiryakioğlu, 2015;Guler et al, 2018).…”

Obtención de la misma dureza por balanceo de fases en las aleaciones Al-Cu-Zn

Se prepararon 5 muestras de las aleaciones Al-Cu-Zn con diferentes porcentajes químicos, utilizando una metodología que pronostica la dureza en este tipo de aleaciones con la finalidad de que todas las muestras tengan la misma dureza (67 RB). Cada una de estas muestras fueron caracterizadas por DRX, Microscopia Electrónica de Barrido (MEB) y un durómetro, se observó el cambio en la estructura. Las muestras utilizadas en condición de equilibrio constan de tres fases que son η, α y τ’, sin embargo, en estas muestras se presentan otras fases como son las fases ε, β y θ. Este trabajo demuestra que es posible aun con los cambios en los porcentajes químicos que son drásticos, es posible tener la misma dureza. La principal causa que se encontró en este trabajo para mantener la misma dureza es el área de contacto de una zona blanca (compuesta por las fases η y ε) con respecto a las otras fases. Si el perímetro de contacto de la zona blanca está dentro de un cierto rango, la dureza de todas las muestras será la misma con un margen de error menor al 3%, esto es importante para desarrollo de nuevas aleaciones con las características mecánicas deseadas.
