Shrinkage
Drying shrinkage may be defined as the volume reduction that concrete suffers as a consequence of the moisture migration when exposed to a high heat flux environment than the initial one in its own pore system.

For semiconductor application wafer thinning plays an important role on device performances guaranteeing for example strong reduction on ON-Resistance (Ron) on power devices.
Optical profilometer images of the as received SiC C- face surface a) and grinded surface b) Despite the same grinding process has been performed on all SiC wafers under investigation, different Cbow values have been measured as it is possible to see from data collected in fig. 2 where Cbow values normalized (N Cbow) to the lowest one, obtained for wafer 1, have been collected.

Fig. 1 The drawing principle in "cassette roller die" There are known and well mastered the processes of bar drawing with simple shape or of
rolling, but few data are known about the process building and the influence of the different factors
in wire drawing between rollers, forming a "cassette roller die".[1]
Advantages as:
▫ the possibility to work metallic materials with a low deformability,
▫ the possibility of growing the speed of process,
▫ rollers are immune to heating wires as the effect of part transformation in heat through
friction
▫ high production through the shortening of the necessary times to change used tools,
▫ the wires with high dimensional uniformity,
▫ is an immune process to oxides presence on the wire surface,
▫ low residuals tensile on the wire surface,
recommend it as a technological accessible solution.
For a higher partial reduction, the elastic deformation of the rollers and of the support assembly is higher (fig. 4) and reveals dimensional modifications for wire (wire material: steel with 0.15% C; 0.60% Mn; 0.35% Si).
