- Abstract
- In order to control the grain size, the spark plasma sintering technique is applied for the manufacturing of Cu-26.7Al-4.05Al(wt.%) shape memory alloy with pure Cu, Zn, and Al element powders. The sintering processes were carried out under different atmospheres. The sintered bodies were denser under Ar or Ar+4%H2 gas atmosphere than under vacuum. With use of small-sized powders, a very small average grain size of 2~3 mm was obtained, but the single phase was not formed. With the large-sized powders the single austenitic phase was observed with the average grain size of 70~72mm. When the different size of raw powders was mixed, it is confirmed that the average grain size of the manufactured alloys was 15mm with single austenitic phase, but the distribution of grain size was not uniform.
