Abstract

Investigation of simultaneous determination of content of surface and dissolved hy-drogen in aluminum and low aluminum alloys was provided by method of heating in an inert gas of argon in electrode impulse furnace of analyzer Leco RHEN-602 followed by detection in the conductivity cell. Operation modes of electrode impulse furnace, allowing complete extraction of surface hydrogen at the first step, and then extraction of dissolved hydrogen from aluminum and low aluminum alloy, were chosen. The measurement procedure was developed using the results of the determination of surface and dissolved hydrogen in different aluminum alloys.
