There is a micro crack
in the matrix due to applied tensile stresses.
During the calcined process, multiples micro crack
are generated, and the form became permeable.
With this crystal the disk crystals block the propagation of a micro crack
in the cemented carbide; the crack must go around the crystals or propagate through the crystals with high resistance.
These assets represent exciting new opportunities in advanced scintillator design, micro crack
detection, dosimeter, photodiode design, and a number of other important growth areas for the 21st century.
02 mm micro crack
on a Pb-free [mu]BGA that went undetected by x-ray (Figure 22).
All LCS machines incorporate Synova's unique water jet guided laser technology (Laser MicroJet) that generates a cylindrical laser beam within a hair-thin water jet, resulting in perfectly parallel walls, tight kerf widths, smooth cutting surfaces and sharp edges, free of micro cracks
, oxidation, depositions and heat affected zone.
Acids do not actually affect the chrome, but hard chrome inherently has micro cracks
Ground penetration radar was used for the survey and micro cracks
were found on the foundation of the Kedarnath shrine.
Next, the thermo-vibration fatigue failure had provoked more micro cracks
, which derivates a catastrophic crack and the solder joint fracture; intermetal-lic clusters and changes in the distribution of solder phases were also observed.
The deformities and resulting surface distortion caused by the drawing and cooling processes for silver wire are repaired with the addition of gold, which fills the micro cracks
and empty spaces between the crystal boundaries to improve transmission properties.
For example, a signal corresponding to Class 1 signifies the existence and development of micro cracks
in the concrete at the interface between the fine aggregate and the cement paste.
The obtained consequences indicated that the micro cracks
were created making a corner to the machined surface and the dendrites were oblique in the route of the maximum cooling gradient .
