: The suitable test equipment for wire-drawing was designed. Wire-drawing tests were carried on with this equipment for TiC/Al2O3 ceramic wire-drawing die. Effect of lubrication medium and drawing velocity... influence on the drawing force. Detailed observations and analyses of the die wear surface reveal that the most common failure of the ceramic drawing die is the wear in the invariable zone and bearing......

Deformation load Fig.5 illustrates the deformation load-stroke curves of AZ31 sheet in cold deep drawing. It is observed that two peaks appear when the die clearance is small (z=0.6 mm), in contrast... the deformation load culminates somewhere during the deep drawing process. On the other hand, the flange gets thicker during the deep drawing process and the resistance to flowing of the material into the die......
