Fig. 9 A poorly transformed microstructure developed by a sluggish quench can result in a quench crack for the U-0.8Ti alloy. Acicular needles are the desired α′ martensite microstructure, while the grayish regions are the undesirable equilibrium α + δ microstructure. More

... properties (less scatter) are best obtained when H 2 levels are maintained at 0.1 ppm or less. Erratic ductile behavior in U-0.8Ti can be offset by controlling the effects of hydrogen by reducing the internal hydrogen content from 0.36 to 0.02 ppm H 2 and testing in dried air containing less than 10...

... is present or is generated during corrosion, UH 3 can form. Additionally, aqueous electrochemical polarization can produce UH 3 directly or hydrated UO 3 . At temperatures above about 200 °C (390 °F), U 3 O 8 becomes the primary corrosion product. Similar to the group IV metals, uranium forms colorful...
