Recycling aluminium (Al 6061) chip through powder metallurgy route

Abstract: The Al 6061 was recycled by using the powder metallurgy technique to determine the effect of particle size distribution on mechanical and microstructure of materials. Analysis of the microstructure, green density and microhardness was conducted to test the performance of recycled aluminium. The project was conducted by using Al 6061 with the addition of 4% of alumina (3-4 μm). The results showed that green density of Al 6061 was lower than pure Al 6061. As the speed of ball mill increases from 100, 150 and 200… Show more

“…Most of them were utilized for food packaging, transportation, food additives, beverage cans, cooking utensils, building medicines, and surgery materials, because of their unique physical and chemical properties [ 3 ]. Whenever the demand and application increased, the waste produced from the machining will also significantly increase [ 4 , 5 , 6 ]. This leads to the production of secondary aluminium to substitute the current use of primary aluminium.…”

“…Por outro lado, o artigo de Fuziana, Y. F. et al (2014) buscou definir a eficiência de sua metodologia por meio de estudo da influência da velocidade de rotação, durante o processo de moagem, na formação de poros em diferentes temperaturas de sinterização, sendo reciclado o material Al 6061. O mesmo destaca uma maior difusão de partículas em temperaturas de sinterização maiores, e que com o aumento da rotação tende a resultar em grãos mais finos, densidade verde e dureza maiores, apresentando materiais com menos porosidade 18 . Contudo, é importante ressaltar que o aumento de velocidade durante a moagem pode acarretar em centrifugação, tornado o processo ineficiente 18 , além de que o aumento na temperatura de sinterização pode acarretar na formação de fase líquida mudando os parâmetros do processo.…”

“…Entretanto, a matéria-prima para este tipo de conformação é o pó metálico, e a sua obtenção depende principalmente de processos como a moagem, ajudam a quebrar o material sólido diminuindo a sua granulometria e ajudando posteriormente a obter resultados satisfatórios na metalurgia do pó, como o aumento da densidade e de algumas propriedades mecânicas à medida que o material apresenta uma menor partícula 18 .…”

“…Microstructure of samples having the lowest green density shows larger and more frequent porosity compared to higher green density samples with smaller and less visible porosity. The Vickers hardness value is in the range from approximately 60-150 HV [9].…”
