A combined experimental and first-principle study on the oxidation mechanism of super austenitic stainless steel s32654 at 900 c for a short time period 1, 3, and 5 h in air is presented.
This paper summarises the results of collaborative research on investment casting of widely used platinum alloys platinum with 5 wt ruthenium pt-5ru and platinum with 5 wt cobalt pt-5co for jewellery purposes.To enable the simulation of the casting process, a materials database was developed as a first step.Casting simulation tools based on computational fluid dynamics cfd were.

The only direct experimental study quantifying the effect of pressure on fe3fe ratios in anhydrous silicate melts of which we are aware is that of gudmundsson and holloway 1990.This paucity of direct measurements is probably due to the experimental dif culties of controlling f o 2 in high-pressure uid-absent experiments.
Objective to investigate whether sleep deprived people are perceived as less healthy, less attractive, and more tired than after a normal nights sleep.Design experimental study.Setting sleep laboratory in stockholm, sweden.Participants 23 healthy, sleep deprived adults age 18-31 who were photographed and 65 untrained observers age 18-61 who rated the photographs.Intervention.
Experimental system validation.Before the experimental study on nanofluids, the experimental system validation is necessary.Water is chosen as the heat transfer medium.Nusselt numbers and frictional resistance coefficients between the experimental results of this paper and the results of published literatures are shown in figs.8 and 9.
To investigate the influence of different direction angles on groove textured surface, tribology experiments for smooth surface and groove textured surface with angles of 0, 30, 45, 60, 90 were carried on under various loads and velocities.The results show that, the friction coefficient decreases first and then increases with the increase of groove direction angle.
We infer that the observed fe isotope fractionation between vapor liquid halite is caused by differences in fe speciation among coexisting chloride-bearing phases.The experimental study confirms for the first time that measurable fe isotope variability can result from phase separation in high temperature hydrothermal systems.

Calculations of the temperature-density paths of the experimental liquids indicate that, at all possible oxygen fugacities, the density must have decreased abruptly after fe-ti oxide saturation.Accordingly, liquids replenishing the intrusion after fe-ti oxide saturation should pond at the bottom of the chamber, quenching against older cumulates.
