Optimization of the mechanical properties of low-carbon steels by formation of a multiphase microstructure
In this work five methods of heat treatments are investigated in order to obtained convenient volume fractions of ferrite, bainite, martensite and retained austenite, starting with a low carbon steel and seeking the ...
Microstructural effects on fatigue crack growth behavior of a microalloyed steel
Thermal transformations on microalloyed steels can produce multiphase microstructures with different amounts of ferrite, martensite, bainite and retained austenite. These different phases, with distinct morphologies, are ...
Design of microstructure of zirconia foams from the emulsion template properties
In this work, we investigate the correlations between structural and rheological properties of emulsified aqueous sol and the porous microstructure of monolithic zirconia foams, manufactured by the integrative combination ...
Microstructure and Thermal Diffusivity of Ceramic
(José Luis Fernández Muñoz, 2013-01-16)
An overview of the microstructures present in high-speed steel - Carbides crystallography
The aim of the work was to prepare an overview about the microstructures present in high-speed steel, focused on the crystallography of the carbides. High-speed steels are currently obtained by casting, powder metallurgy ...
Birefringent microstructures fabricated by two-photon polymerization containing an azopolymer
(Optical Society of America - OSAWashington, 2013-01)
Birefringent materials have many applications in optical devices. An approach to obtain optically induced birefringence is to employ a guesthost strategy, using a polymer matrix containing an azodye. However, such method ...
MICROSTRUCTURAL CHARACTERIZATION OF CP STEEL USED IN AUTOMOTIVE INDUSTRY
