材料科学技术（英文）

Isothermal aging behaviours of a CuZnAl shape memory alloy have been investigated by means of dilatometry.The length of the specimens during isothermal aging from 190 to 280℃ increases with the aging time at each temperature.The isothermal aging kinetics fits in Avrami equation and the time exponent...

Relationship between Relaxation Internal Friction Peak at about 200℃(f≈1Hz)and Bainitic Transformation In a CuZnAl Alloy

ZHAO Zengqi CHEN Feixia YANG Dazhi BAO Er ** Physical Laboratory , Baotou Research Institute of Rare Earth , Baotou , 014010 , China*** Dept.of Materials Engineering , Dalian University of Technology , Dalian , 116024 , China**** Dept.of Materials Engineering , Yanshan Uni

材料科学技术（英文）

The present investigation showed that the re- laxation peak at about 200℃ (f≈1Hz) was related to bainitic transformation in a CuZnAl alloy.The peak decreased when bainite precipitated.The activation energy of the peak was the same as the apparent activation energy of bainitic transforma- tion.Accord...

Estimation of Thermodynamic Properties from Binary Phase Diagram

WANG Jixin Baotou Research Institute of Rare Earths , Baotou , 014010 , China

材料科学技术（英文）

The general relationship between binary phase diagrams and the thermodynamic properties was system- atically derived without any assumption.A procedure was presented to estimate the thermodynamic proper- ties from the binary phase diagrams....
