Professional Degree Theses
"A method will be described wherein the absorption of hydrogen by aluminum is evaluated using hydrogen 3 as a tracer element. Results show that hydrogen gas is readily absorbed into the melt when it is injected directly, but is not taken on from the combustion products, that quantities of it are released when the metal freezes, and that the commonly used methods of fluxing with chlorine and nitrogen gas are of value for degassing"--Preface, page iii.
