    Análisis de la aleación mecánica de aluminio 1060 con porcentajes controlados en peso de zinc y su incidencia en la resistencia última a la tensión, dureza e impacto
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Mecánica Mención Diseño, 2019) Pineda Silva, Giovanny Vinicio; López Villacís, Gonzalo Eduardo
    The research project begins due to the need to have technically documented information related to powder metallurgy within the scope of mechanical alloy, manufacturing process that is entering into the National Industry, due to the advantages it presents with respect to traditional processes; being the most representative, a more exact control of the limits of the composition, optimization of raw material and is a process susceptible to automation with good surface finish for serial production of mechanical components. The experimental process of the mechanical alloy begins with the obtaining of mechanical powder of the base elements: Aluminum 1060 with particle size 30 micrometers and alloying: Zinc with particle size between 45−63 micrometers through the use of ball mill and a screening control; mixing process based on the percentages in weight defined for the subsequent compaction and sintering of the test pieces for the correct development of the tests. The study of tensile strength, hardness and impact was developed though the control of variables of percentage by weight of alloying element: 0.5 – 1.0 y 1.5 percentage Zinc, and sintering temperature: 462 celcius degrees y 594 celsius degrees ; the best results were obtained in the case of a study developed with 1 percentage Zinc and a temperature of 594 celsius degrees, where the hardness and tensile strength were increased by 69 percentage and 12.29 percentage respectively in relation to the base element; while the impact resistance as a function of the energy absorbed decreases by 39.40 percentage in the best case 1 percentage Zinc and 462 celsius degrees; in addition, the controlled variables are correlated with each other and directly affect the properties under study according to the statistical analysis developed by Fisher’s test.

    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Carrera Ramos, Diego Salvador; López Villacís, Gonzalo Eduardo
    The experimental work was based on the study of the basic mechanical properties (ultimate tensile strength, yield strength, hardness, impact resistance) of aluminum alloy 1060 with magnesium in its different volumetric fractions, the approach of the study arises from the appearance of new materials that are used in the construction of mechanical elements that are part of vehicles and other means of transport, with properties equal or superior to those of traditional materials, being replaced by some of its advantages among which we have its reduced weight and low cost, the alloyed material was subjected to traction hardness and impact analysis obtaining the final results of each of the tests. For the execution of the tests the ASTM standards that regulate the execution of the tests were used, thus the following norms were used: (ASTM E8-00b, ASTM E10-01 Hardness, ASTM E23-01 Impact), this way they executed the analyzes and it was possible to establish the volumetric fraction that presented the best results. With the results obtained it was determined that the groups with the best mechanical characteristics are the Y1 group for tensile tests and the Y2 group for hardness and impact tests presenting the following average properties, ultimate tensile strength: 53.19 MPa, limit creep: 7.29 MPa, hardness: 41.98 HB, impact resistance: 1.12 J / cm2.
