Conducting experiments in an inert shielding-gas environment limits the likelihood for experiencing significant mass loss or compositional shifts due to differential relative evaporation. Species-specific evaporation is proven to be below prescribed limits and near-real time monitoring of the potential for exposure is shown to be an effective tool to ensure astronaut safety. The activity coefficients for key constituents in the alloy are defined as a function of temperature for inclusion in next-generation toxicity tracking software.

在国际空间站上跟踪镍基高温合金悬浮处理过程中的蒸发

在惰性保护气体环境中进行实验限制了由于不同的相对蒸发而出现显着质量损失或成分变化的可能性。特定物种的蒸发被证明低于规定的限制，近乎实时的暴露潜力监测被证明是确保宇航员安全的有效工具。合金中关键成分的活性系数被定义为温度的函数，以包含在下一代毒性跟踪软件中。
