    En el marco del crecimiento de la actividad económica del sector turístico, la cual representa un 7% del PBI anual en Argentina (US$53.000 millones) y la vinculación con los dueños de Senderos Apart—Hotel, se impulsó la ...
  • Jonsson, S. (INTEMA - UNMdP-CONICET, 2014-11-13)
    Thermodynamic calculations and Scheil-Gulliver simulations are used for simulating solidification of gray cast iron, systematically varying the composition around Fe-3.35C-2Si by adding Cr, Ni, Mn, Mo, Cu, S, P, and in ...
  • Ganim, Esteban Ismael; Perez, Cristian Marcelo; Scolarici, Juan Sebastián (Universidad Nacional de Mar del Plata. Facultad de Ingeniería. Argentina, 2017-03-01)
    En el presente proyecto final de grado se diseñó una vivienda sustentable. Para lo cual se analizaron las condiciones ambientales, y las distintas energías disponibles para una vivienda en la localidad de Mar del ...
  • Diószegi, A.; Fourlakidis, V.; Lora, R. (INTEMA - UNMdP-CONICET, 2014-11-13)
    Primary austenite has been underestimated in general when the theories of nucleation, solidification, microstructure formation and mechanical properties was established for cast iron and particularly for lamellar cast iron. ...
  • Di Muoio, G.L.; Skat Tiedje, N.; Budolph Johansen, B. (INTEMA - UNMdP-CONICET, 2014-11-13)
    Gas generated during the casting process can cause defects that increase the cost of the components and possibly lead to scrapping the parts. Gases are produced during evaporation of water and by decomposition of organic ...
  • Burbelko, A.A.; Początek, J.; Kapturkiewicz, W.; Wróbel, M. (INTEMA - UNMdP-CONICET, 2014-11-13)
    For the modelling of the equiaxed grain growth controlled by diffusion the spherical Elementary Micro-Diffusion Field (EMDF) is usually used. Unfortunately, deviation of the idealized spherical grain geometry from the real ...
  • Bedolla-Jacuinde, A.; Guerra, F.V.; Mejía, I.; Zuno-Silva, J.; Maldonado, C. (INTEMA - UNMdP-CONICET, 2014-11-13)
    This work analyses the secondary carbides precipitation during the destabilization of a 17%Cr white iron containing 195 ppm Boron. The experimental iron was characterized in the as-cast conditions to have comparable ...
  • Otero, Fernando Agustín (Universidad Nacional de Mar del Plata. Facultad de Ingeniería. Argentina, 2016-06-08)
    The analysis of particle systems by means of Static Light Scattering (SLS) measurements may procure different types of information about morphological characteristics of the particles. Their size, shape, constitution and ...
  • Papis, K.; Tunzini, S.; Menk, W. (INTEMA - UNMdP-CONICET, 2014-11-13)
    Downsizing of engines – gasoline as well as Diesel - helps to reduce CO2-emissions. Smaller engines at the same or even raised power levels result in higher exhaust gas temperatures. In personal cars, these are raised to ...
  • Ghasemi, R.; Elmquist, L. (INTEMA - UNMdP-CONICET, 2014-11-13)
    Cast iron is assessed as a self-lubricating material under sliding conditions. This is due to the graphite particles distributed in the matrix, which come out from their pocket, and form a tribofilm between the mating ...
  • Svidró, P.; Elmquist, L.; Dugic, I.; Diószegi, A. (INTEMA - UNMdP-CONICET, 2014-11-13)
    Shrinkage porosity and metal expansion penetration are two fundamental defects appearing during the production of complex shaped lamellar cast iron components. Simplified test models simulating the thermal and geometrical ...
  • Pagnussat, Mariana Sabina (Universidad Nacional de Mar del Plata. Facultad de Ingeniería. Argentina, 2008-03-01)
    Los estudios acerca de la utilización de desechos agrícolas como materiales de refuerzo en compuestos poliméricos han aumentado notablemente en los últimos años. Esto se debe principalmente a las posibles mejoras en ...
  • Judewicz, Marcos Gabriel (Universidad Nacional de Mar del Plata. Facultad de Ingeniería. Argentina, 2016-03-22)
    En la inyección de energía a la red eléctrica, el control de corriente del inversor debe responder de forma rápida frente a los cambios en la red eléctrica, entregar la energía a la red eléctrica con una distorsión armónica ...
  • Brisuela Blume, Lisandro Nicolás (Universidad Nacional de Mar del Plata. Facultad de Ingeniería. Argentina, 2015-07-01)
    En el presente trabajo se realiza en el Capítulo 1 una breve descripción a cerca de los motores de inducción trifásicos, los variadores de velocidad y su interrelación, que tienen como resultado corrientes dañinas en los ...
