Deformation behavior of semi-solid Zn-Al alloy filler metal during compression

► Semi-solid Zn-Al alloy discs with a (h/d) of 0.6, 0.3 and 0.1 were compressed. ► A comparison was made of their stress-strain curves during compression. ► Shape changes of the solid grains in the discs during compressions were examined. ► Interactions on the contact surface during disc compressions were analyzed. ► Discs were used as a filler metal in the semi-solid brazing of SiCp/Al composites.
