In the present study, production of titanium and Ti6Al4V alloy foams has been investigated using powder metallurgical “space holder technique” in which magnesium powder were utilized to generate porosities in the range 30 to 90 vol. %. Also, sintering of titanium and Ti-6Al-4V alloy powders in loose and compacted condition at various temperatures (850-1250oC) and [...]

Products of work machines nails use SAE/AISI 4340 steels. Steels have high hardenability and it gets to hardness. So these steels can obtain toughness.These toughness hasn’t important dropping.We use these steels because this is important event for sector. Manifacture of casting, forcing or another methods at nails have some characteristic. Nails have characteristic with heat [...]

In order to determination the possibilities in the reduction of nitrite level
and fermentation time, the effects of fermentation time (13 days), nitrite level (45-
195 ppm) and heat treatment (30-90 ºC) on biogenic amine formation and some
physical-chemical, microbiological and sensory properties of Sucuk were
investigated by using Central Composite Design of Response Surface Methodology.
Fermentation time decreased Micrococcus-Staphylococcus [...]
