Opis:: Outstanding properties of sintered ceramics due to lower sintering temperatures and smaller grain sizes are of much attention to many researchers. In this study, YAG phase was formed successfully with mechanical activation of powder mixtures by high energy ball milling of powders at different speeds. The powders were compacted and sintered at three different temperatures to evaluate the sintering density, phase formation and grain formation. It was found that increasing activation time, which agitates the powder mixing more accurately, has led to an increase in the relative density, as compared to non-activated samples, sintered at same temperatures. Up to 95% ot the theoretical density were reached, indicating the partial liquid phase formation of Y-A related phases. YAG phase formation and crystallite size were evaluated using XRD and Debye-Scherrer formula. The studies of grain size and surface morphology were conducted using SEM. Since the mechanical activation of ceramic powders occurs by fragmentation and crack propagation, by brittle fracture of powders, the main mechanism of reduction of sintering temperature can be concluded to be the decreasing grain size, as well as the increasing strain on fine powder grains.

Opis:: In this study, structural or physical properties such as the unevenness, hairiness and frictional properties of cotton-modal blended yarns were studied. For this purpose, 100% cotton, 50/% cotton/modal and 100% modal ring spun yarns were produced in five different twist coefficients (αe: 3.5, 3.7, 4.0, 4.2, 4.5) and four different yarn linear densities (21, 25, 30 and 37 tex). General factorial design was used and the response surface was plotted for analysing the data. In conclusion, the most influential factors for the yarn characteristics were the yarn linear density and blend ratio. Contrary to expectations, the twist coefficient factor had a minor effect on yarn characteristics, especially on the friction coefficient.
W pracy badano właściwości strukturalne i fizyczne, takie jak nierównomierność, włochatość i właściwości cierne przędz bawełnianych. W tym celu wytworzono przędze obrączkowe o różnym stosunku mieszanki: 100% bawełna; 50% bawełna/50% modal i 100% modal z pięcioma różnymi współczynnikami skrętu (αe: 3,5; 3,7; 4,0; 4,2; 4,5) i czterema różnymi masami liniowymi (21, 25, 30 i 37 tex). Dokonano charakterystyki tarciowej poszczególnych przędz. Stwierdzono, że czynnikami mającymi największy wpływ na charakterystykę tarciową były masa liniowa i stosunek mieszanki przędzy. Wbrew oczekiwaniom współczynnik skrętu miał niewielki wpływ na charakterystykę tarciową przędzy, a zwłaszcza na współczynnik tarcia.

Opis:: The purpose of this study is to investigate the use of İzmir (Menderes-Cumaovası) expanded perlite as a construction raw material by determining its characteristic properties, as well as its physical properties at different temperatures (up to 600°C). The perlites, having glassy, porous structure, were found to contain 70.68% SiO2 and 13.04% Al2O3. The physical properties of the perlites changed with temperature. The highest surface area, 524 m2/g, was obtained at 400°C. The physical properties were found to have high statistical relation. It was concluded that expanded perlite aggregates could be used as a construction raw material.

Opis:: The study compares the microstructure of three commercial dental cobalt matrix alloys with related chemical composition declared by the manufacturer. Casts were produced with lost wax method, then melted and casted with centrifugal induction casting machine. The Co-Cr-Mo alloys were casted according to the manufacturers procedure. The samples’ chemical composition and phase composition, respectively, using WDXRF (Wavelength Dispersive X-Ray Fluorescence) and XRD (X-ray Diffarction) methods were analysed. Casts microstructure by mean of LOM (Light Optical Microscopy), SEM (Scanning Electron Microscopy) and EDS (Energy Dispersive X-ray Spectroscopy) were investigated. Vickers hardness HV10 was measured. Quantitative microstructure evaluation was performed by means of computer image processing. The results of the chemical composition indicate the high stability of the chemical composition for alloy A. In case of alloys B and C, there was a significant difference in carbon content. Quantitative differences in image of microstructure between of castings A and B, C were noticed. The greater amount of precipitates was recorded for castings with higher carbon content. In all investigated castings, the presence of β matrix solution and M23C6 carbide precipitations was found.
