摘要
摘要研究了贫铀及其低合金钼合金(U-2wt)的氧化动力学。在60和75℃的潮湿空气(75%相对湿度)中测量了%Mo, u -5wt, %Mo),并确定了线性氧化动力学的反应速率方程系数。贫铀在75℃的氧化过程中,大约2500小时后,反应动力学从线性行为转变为指数行为。
The oxidation kinetics of depleted uranium and its low-alloy molybdenum alloys in moist air
Abstract The oxidation kinetics of depleted uranium and its low-alloy molybdenum alloys (U-2wt.%Mo, U-5wt.%Mo) were measured in a moist air (75% relative humidity) at 60 and 75 ° C. Coefficients of reaction rate equations were determined for linear oxidation kinetics. In the oxidation of depleted uranium at 75 ° C, a change in reaction kinetics from linear to exponential behaviour was observed after about 2500 hours.
