Book Description
This Standard specifies the measurement principle, instrument requirements, test conditions, test procedures, and test report of the closed gas loop circulation method for measuring hydrogen content in liquid aluminum and aluminum alloys. This Standard applies to the determination of hydrogen content in liquid aluminum and aluminum alloys. 2 Measurement principle The closed gas loop circulation method uses a circulation system to promote the diffusion of hydrogen in the aluminum melt into a quantitative volume of inert gas, until the hydrogen partial pressure reaches equilibrium. It uses the thermal conductivity test principle to test the change in thermal conductivity of circulating gas due to hydrogen, and measure the partial pressure of hydrogen Pi. The calculation method of hydrogen content is as shown in formula (1): where: [H] - the hydrogen content, in cubic centimeter per 100 grams of aluminum (cm3/100 g Al); Pi - the hydrogen partial pressure, in kilopascal (kPa); K - the alloy correction coefficient, determined by referring to formula (2). The correction coefficient K of commonly used aluminum and aluminum alloys is shown in Table 1; S0 - the solubility of hydrogen in pure aluminum, which is a function of temperature, as shown in formula (3), in cubic centimeter per 100 grams of aluminum (cm3/100 g Al).
