Characterization of ceramic pastes by an indentation hardness test
BRISCOE, BJ; Özkan, Necati (1997-01-01)
Certain material deformation properties of a typical alumina based ceramic paste system, including the hardness (a plastic yield characteristic), the elastic modulus, a plasticity index (a measure of the relative elastic-plastic response), and a mean flow stress, are obtained using an indentation hardness test. In order to compute these material properties a contact compliance procedure, in conjunction with an analysis based upon an adaptation of the Box-Cox curve fitting method for the compliance curve, ha...
Toughening of polylactide by blending with various elastomeric materials
Meyva, Yelda; Kaynak, Cevdet; Department of Polymer Science and Technology (2014)
The purpose of the first part of this thesis was to investigate influences of three different ethylene copolymers on the toughness and other properties of very brittle biopolymer PLA (polylactide). For this aim, PLA was melt blended by twin-screw extruder with various amounts of ethylene vinyl acetate (EVA), ethylene methyl acrylate (EMA) and ethylene-n-butyl acrylate-glycidyl methacrylate (EBA-GMA). SEM and DSC analyses indicated that these ethylene copolymers were thermodynamically immiscible with phase s...
Characterization of steel microstructures by magnetic barekhausen noise technique
Davut, Kemal; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2006)
This aim of this thesis is to examine the possibility of using Magnetic Barkhausen Noise (MBN) technique in characterizing the microstructures of quenched and tempered low alloy steels as well as annealed low carbon steels. To determine the average grain size by MBN, SAE 1010 steel consisting of dominantly ferrite was used. The specimens were slowly cooled in the furnace after austenitizing at different time and temperature variations. By metallographic examination the average ferrite grain size of specimen...
AKINOKTEM, G; TINCER, T (Wiley, 1994-11-21)
Thermal and flow properties of perlite-filled high-density polyethylenes (HDPE), studied in the first part of the paper, are discussed. Maximum peak temperatures of endotherms (T-mp) and the corresponding relative peak heights were examined by differential scanning calorimetry (DSC). The data obtained from a Brabender torque rheometer were evaluated to find the melt viscosities at low shear rate during preparation of perlite-HDPE composites. The filler concentration, types of HDPEs, and the use of gamma-APS...
Determination of Deformation Distributions in Welded Steel Tension Elements Using Digital Image Technigues
Sözen, Şahin; Güler, Murat (2010-09-27)
It is known that material properties, connection quality and manufacturing methods are among the important factors directly affecting the behavior of steel connections and hence steel structures. The possible performance differences between a fabricated connection and its computer model may cause critical design problems for steel structures. Achieving a reliable design depends, however, on how accurately the material properties and relevant constitutive models are considered to characterize the behavior of...
