摘 要：The gas released from the titanium hydride decomposition is one of the key factors to influence the Al alloy melt foaming process.In this study,a set of decomposition kinetic equations of titanium hydride was acquired by separating its temperature programmed decomposition（TPD） spectrum,which was acquired by a special designed TPD apparatus with argon used as carrier gas and thermal conductivity cell as the detector.According to these equations,the decomposition and hydrogen release characteristics of titanium hydride at a fixed/elevated temperature are described quantitatively,which can be applied to forecast the Al alloy melt foaming process and furnish the theoretical basis for fabrication of three-dimensional complex shaped Al alloy foam.
