| Abstract: | A simple and easy method with high accuracy has been introduced for the determination of hydrogen absorption properties of alloys, such as hydrogen absorption capacity , paressure-composition isotherms and thermodynamic parameters ΔH and ΔS.
The apparatus is described in details. The equilibrium data can be obtained under hydrogen pressure of 16-0.0001 MPa and in the range of temperature -196-+500 ℃. |
