| 摘 要： | 对冷变形金属进行等温加热转变制备半固态LC9铝合金坯料，并对其工艺过程及组织演变进行了研究，讨论了变形量、加热温度和保温时间等工艺参数对LC9铝合金组织的影响。结果表明，对冷变形金属采用等温处理，可获得均匀、细小的半固态坯料，很好地满足半固态制坯的要求；增加变形量使组织中的液相比例明显增加，晶粒尺寸变小；提高加热温度或延长保温时间有利于晶粒粒化，但是过高的温度和保温时间，会加快晶粒长大，促使晶粒粗化。 |
| 关 键 词： | 等温加热 半固态LC9铝合金 组织演变 |

| Abstract: | The effects of deformation,heating temperature and holding time on microstructure of LC9 alloy in producing semi-solid billet by strain induced melt activated(SIMA) process were studied and structure evolution of semi-solid LC9 aluminum alloy was observed.The results show that by strain induced melt activated process,a semi-solid ingot of LC9 aluminum alloy with fine and desired non-dendrites microstructure has been obtained,which well fit to the requirement of semi-solid forming.But too great temperature and holding time will lead to coarsing grain size |
| Keywords: | strain induced melt activated(SIMA) semi-solid LC9 aluminum alloy structure evolution |
