These results show that for the same grain width (0.52 mm) an increase in the grain length causes an immedi- ate increase in the fracture toughness of silicon nitride, independent

Electrochemical response of ferri/ferrocyanide redox couple is discussed for a system that uses reticulated vitreous carbon (RVC) three dimensional electrodes prepared at

According to the case analyzed here, which involves the weld repair of a 1¼Cr½Mo ferrite-pearlite steel steam pipe operating for 20 years at 480 °C, in service weld repair leads

Consequently, if roughness is present in the surface and it is quantified, we propose that this type of contact stiffness analysis can be used for correct to

agreement was not good but much better than for the periodic nuclei. Area fraction against time, simulated by CA. Interfacial area length between recrystallized grains and matrix, L

Further investigations are under way to assess the influence of niobium carbide content on the microstructure and its effect on hardness and fracture toughness of the

The roots were fixed in glutaralde- hyde, sacarose and sodium cacodylate, and demineralized in EDTA, glutaraldehyde and sodium hydroxide activated by a microwave oven (Sharp,

Aiming to improve the knowledge on the low- temperature plasma nitriding of sintered PIM 316L austenitic stainless steel, the effect of nitriding temperature and time on the
