High-entropy alloys (HEAs) prefer to form single-phase solid solutions (body-centered cubic (BCC), face-centered (FCC), or hexagonal closed-packed (HCP)) due their high mixing entropy. In this paper, we systematically review the mechanical behaviors and properties (such as oxidation corrosion) of BCC-structured HEAs. The at room temperature temperatures samples prepared by different processes (...

in the present work, deoxidation and refining of 316lvm steel (low carbon vacuum melted) during the vacuum induction melting process was studied. this grade of stainless steel is one of the most important materials in medical applications. vacuum deoxidation by carbon is the first stage of 316lvm stainless steel production process. in this stage, aluminum must be absent to avoid killing the c-o...

purpose: to evaluate the effect of vacuum and flow rate on endothelial cell loss after high versus low vacuum phacoemulsification. methods: this randomized clinical trial was performed on 60 eyes of 60 patients with moderate lens opacity (nuclear sclerosis 3+). all surgeries were performed by one experienced surgeon using stop and chop technique with sovereign white star machine (amo). patients...

Background and Objectives: Macrobrachium nipponense are wetland crustaceans. The shrimp is rich in protein and unsaturated fatty acids (FAs). Therefore, the aim of this study was to use M. nipponense as a supplement for the preparation of a new soup. Materials and Methods: Nearly 40 kg of M. nipponense were harvested from Anzali Lagoon, Northern Iran. Shrimps were washed and dipped in NaCl sol...

Macroporous, partially L10-ordered Co-Pt films with nearly equiatomic composition were successfully synthesized by electrodeposition from an aqueous sulfate–chloride electrolyte on colloidal crystal-templated substrates, followed annealing in vacuum. The colloids deposited the substrate consisted of amidine-functionalized polystyrene spheres 215 ± 13 nm diameter, which self-assembled electropho...

Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...
