of the substrates on the isothermal crystallization rate of a high density polyethylene(HDPE) were presented. Two methods were used to characterize the crystallization rate: the change of turbidity of the HDPE specimen and the changes of the complex viscosity and storage modulus measured by a rotational rheometer, which gave consistent results showing that the isothermal crystallization rate decreased......

Determination of isothermal section of Fe-Ti-Zr ternary system at 1 173 K ZHOU Guo-jun(周果君), JIN Shan(金 姗), LIU Li-bin(刘立斌),LIU Hua-shan(刘华山), JIN Zhan-peng(金展鹏) School of Materials Science... approach together with electron probe microanalysis(EPMA) technique. A series of tie lines and tie-triangles were determined and the isothermal section at 1 173 K was established, which consists......
to the crystallization kinetics of Zr60Al15Ni25 bulk amorphous alloy is investigated by differential scanning calorimetry(DSC) under isochronal and isothermal conditions. A criterion xm, at which a defined... of xm at different isothermal annealing temperatures (743, 748, 753 and 758 K) are almost near 0.632, which indicates that the isothermal crystallization kinetics can be modeled by JMA equation. However......
