After exposure to the microcracking condition, the fired cordierite body has a microcrack parameter (Nb3) at least 20% greater than the microcrack parameter prior to exposure to the microcracking condition.
A cracking flexure (182) provides the cracking force.
In this case, the cracking may be accomplished by, for example, mechanical bending or laser cracking.
This cracking prevention layer prevents the cracking and deformation of the optical compensation layer.
Further, the apparatus cools, heats and re-cools the borehole wall, thereby measuring the first cracking temperature, the second cracking temperature, and the cracking point.
Crack inhibitors can also prevent or retard crack growth.
Sustained load crack resistance
The fired cordierite body has a microcrack parameter (Nb3) of about 0.05 to about 0.25 prior to exposure to a microcracking condition.
Carburizing such steels in the past has led to surface cracking, but here, the deep hard case creates compressive stresses at the surface and prevents cracking.
Sulfide stress cracking resistance
This process enables one to avoid cracking of the cathode.
sulphide stress-corrosion cracking
The method may further include a breaking step.
The needles have improved resistance to cracking.
The new welding process avoids cracking in welding, in repair welding or in cladding of parts of metallic alloys which are sensitive to hot cracking.
The composition has excellent storage stability, permits thick coating with little mud-cracking, and can form a coating which does not cause cracking or discoloration in baking.
A detector for detecting the cracking sound of plate glass under polishing while discriminating it from the cracking sound of other plate glass.
Thus, the lead-free brass alloy is provided which is inhibited from suffering the cracking caused by that corrosion and hence has improved resistance to stress corrosion cracking.
Disclosed is an HID lamp having a structure that, even if cracking occurs, can prevent the propagation of cracking in a sealing site.
