| 中文摘要 | Hot deformation behavior of a stir cast and hot extruded 14 vol% SiCp/2014Al composite was studied at temperatures from 355 to 495 degrees C and strain rates from 0.001 to 1 s(-1), including microstructure evolution and damage formation. Stress-strain rate fitting was optimized to construct accurate processing maps based on modified dynamic materials model (MDMM). In addition, the strain rate sensitivity maps were plotted, indicating more significant effect of temperature on deformation mechanism than strain rate. The dissipation efficiency versus temperature curves indicated: (i) a transition from dynamic recovery (DRV) to dynamic recrystallization (DRX) at 400 degrees C; (ii) occurrence of dynamic grain growth (DGG) at 400-440 degrees C; (iii) existence of equicohesive point (T-eq) of 450 degrees C (similar to 0.8 T-m) above which grain boundaries weakened and contributed to plastic deformation. The particular fluctuation of temperature sensitivity at 440 degrees C was caused by an abnormal grain growth. (C) 2017 Elsevier B.V. All rights reserved. |
