La búsqueda de objetos que sean
únicos y no manufacturados de forma
masiva, ha sido una tendencia de los
consumidores en los últimos años, gracias a
técnicas de producción como la prototipado
rápida, específicamente por el proceso de
adición de material, nuevos productos que se
ajustan a nuestro ...
Este trabajo tiene como objetivo estudiar la influencia del tamaño de grano y la inclusión de Níquel
como elemento aleante en las propiedades resistivas a la corrosión en un acero autopatinable
A242.
Esto se logró mediante la determinación de parámetros de corrosión, velocidad de corrosión y
espe...
This work aims to study the influence of grain size and Nickel as an alloying element in the
corrosion resistive properties of a A242 weathering steel.
This was achieved by determining corrosion parameters, corrosion rate and corroded thickness
using gravimetric method according to ASTM G1 and...
Copper matrix compounds (CMCs) with high mechanical and electrical properties are candidates for use in advanced electrical applications such as spot welding electrodes, high-performance electrical switches, neutron rotating target backups, brushes, among others. The powder metallurgical route (P...
En este trabajo se obtuvo un compuesto de matriz de aluminio realizando molienda mecáni-ca de polvos de aleación A356, fabricados mediante el proceso de electrodo rotatorio, con diferentes fracciones másicas de partículas de SiC, los cuales posteriormente fueron some-tidos a proceso de sinterizac...
In this work, an aluminum A356 matrix composite was obtained by mechanical milling, manu-factured by the rotary electrode process, with different SiC particles mass fractions, which were subsequently subjected to a sintering process. The diffraction data shows a complex microstructure, and that e...
A partir de un acero 0,204%C 1,88%Mn 0,88%Si y 0,13%Al laminado en frío y de microestructura inicial ferrita-perlita, se estudió el efecto del tratamiento térmico en la microestructura resultante, en la estabilidad de la austenita y en las propiedades mecánicas. Los aceros fueron tratados térmica...
From a 0.204%C-1.88%Mn-0.88% Si-0.13%Al steel, cold rolled and ferrite-pearlite initial microstructure, the effect of heat treatment on microstructure, austenite stability and mechanical properties was studied. Steels were heat treated by intercritical annealing (IA) at 750°C under different cond...
El desarrollo de esta tesis doctoral busca contribuir al conocimiento científico relacionado con la fabricación de dióxido de titanio mediante la inserción de defectos, conocido también como TiO2 autodopado. Para esto, se postularon dos aproximaciones no descritas en la literatura científica para...
The development of this doctoral thesis seeks to contribute to scientific knowledge related to the manufacture of titanium dioxide through the insertion of defects, also known as self-doped TiO2. For this, two approaches not described in the scientific literature were postulated to emulate the mo...
This work is focused on the modelling of post casting cooling and heat treatment stages, using a
coupled thermo-mechanical metallurgical model in order to understand the behavior of
bimetallic rolling mill rolls. The case of interest is a bimetallic rolling mill roll which materials
and geometry ...
Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil fuels with bio-based fuels or full electrification. For heavy-duty trucks, th...
Esta Tesis plantea la pregunta de si el uso de morteros con parafinas
microencapsuladas combinado con colectores solares térmicos puede
reducir el consumo de energías convencionales, en un sistema tradicional
de suelo radiante. Se pretende contribuir al conocimiento acerca del efecto
que produce ...
This Thesis proposes the question of whether the use of mortars with
microencapsulated paraffin combined with solar thermal collectors can
reduce conventional energy consumption in a traditional heating floor
system. It aims to contribute to knowledge about the effect that it has on the
build...
The hydraulic transport of solids (hydro-transport) in the form of slurry is an essential technology for transporting large volumes of raw, process and waste materials in several industries such as oil and gas, metallurgy and mining. However, although this type of transport system is considered s...
