| Abstract |
The mechanical Properties and grain size of the coldrolled Al-11%Zn base alloys contained Ti or Mn metal have been investigated. The results obtained for the specimens heated at different temperature for various time periods are as follows; 1) The grain refinement effect of Ti was observed at high temperature when Ti content was small (0.29wt % Ti) 2) In general, the elongation of annealed and air cooled alloys containing Ti or Mn was observed greater than that of water-quenched same alloys. 3) The small addition of Ti caused the elongation to increase, approximately, up to 44%, but didn`t effect the large change in tensile strength. 4) The age hardenability of the alloy due to the addition of Ti or Mn is not likely to exist. 5) The improvement of mechanical properties of the alloy seems to be better for the case of Ti addition than that of Mn. |
