The influence of heat treatment holding temperatures from 600 to 1300 °C on the microstructure, mechanical properties and corrosion resistance in selective laser melted (SLMed) 304L stainless steel is investigated this work. results reveal that there no remarkable microstructure change after at for 2 h, while recrystallization leads a slight decrease grain size temperature range 700–900 °C. 100...

Abstract This study was conducted to determine the seeding rate reducing and potassium spraying on growth yield of local millet, at Abu Chwilana region (8 km north governorate), during summer season 2022 carry out by factorial experiment with Randomized Complete Block Design (R.C.B.D), first factor include three rates were 8, 10 12 kg ha −1 , second four spray treatment levels, 0, 3000, 6000 90...

We report a first major upgrade of Inforex — a web-based system for qualitative and collaborative text corpora annotation and analysis. Inforex is a part of Polish CLARIN infrastructure1. It is integrated with a digital repository for storing and publishing language resources2 and it allows to visualize, browse and annotate text corpora stored in the repository. As a result of a series of works...

Preparing high relative density ?-TiAl alloy by pressure-less sintering at low-cost has always been a challenge. Therefore, new kind of non-spherical pre-alloyed TiAl powder was prepared the reaction TiH2 and Al 800 °C to fabricate high-density Ti-48Al via sintering. The oxygen content controlled below 1800 ppm using coarse (~120 ?m). sintered densities ranged from 92.1% 97.5% with temperature ...

the direct sulfation of three high purity iranian limestones and one precipitated calcium carbonate from different sources, containing more than 97 % caco3, were studied in a specially designed fixed bed reactor under atmospheric pressure, in the presence of excess co2 to prevent decomposition of caco3. experiments were carried out over a range of particle sizes from 1.6-2.5  mm at four tempera...

The gas sensing properties of resistive gas sensors of BaFe0.7Ta0.3O3−δ (BFT30) prepared by the socalled aerosol deposition method, a method to manufacture dense ceramic films at room temperature, were investigated. The electrical response of the films was investigated first under various oxygen concentrations and in a wide temperature range between 350 and 900 C. Between 700 and 900 C, the con...
