英文摘要	An investigation was performed on the effects of semi-solid compression parameters, such as strain rate, compression temperature and heating time at these temperatures on deformation behaviors of two kinds of ZA27 alloys, one was modified by Zr and the other was unmodified. The results indicate that with the increase of strain, the stress of the modified composite first sharply increases to a peak value, then dramatically decreases to a plateau value, and again increases till the end of deformation. But for the unmodified one after being up to a peak value, the stress only decreases slowly. As the compression temperature or the heating time decreases, or the strain rate increases, the stress level and the cracking degree of these two kinds of alloys increase. Under the same deformation conditions, the stress level and the cracking degree of the unmodified alloy are higher than that of the modified one. There is an exception that the stress level of the unmodified alloy is minimum and smaller than that of the modified one when deformed at the low temperature of 450°C. These phenomena were discussed by analyzing the microstructure under different conditions and the deformation mechanisms at different deformation stages.
