microcracking การใช้

• The interplay between matrix microcracking and fiber-matrix debonding often dominates the failure mechanism of SiC / SiC composites.
• By the constraint of oxidation to the outer layers of the part, reduced levels of microcracking occur in the finished part.
• Decompression causes significant volume expansion ( called "'relaxation "') due to microcracking and the exsolving of enclathratized gases.
• Low coefficient of thermal expansion and inherent resistance to microcracking make it well suited to cryogenic tank use and also part of vehicle structure ., Nonburnite will be used in the tanks of the Lynx rocketplane.
• This microcracking behavior leads to superior corrosion resistance ( the cracks are so small and numerous that it is difficult for aggressive media to penetrate and attack the reinforcing steel ) as well as to self-healing.
• This reduces thermal gradients in the concrete, which prevents the occurrence of microcracking which can weaken the concrete and reduce its durability, and was used for this purpose in the construction of the Jack Lynch Tunnel in Cork.
• If sufficiently thickened, these layers may decrease the radiodensity of the bone; therefore, the first radiographic evidence of previous osteonecrosis may be patchy histologically and are characterized by extensive delamination or microcracking along cement lines as well as the formation of excessive cement lines.
• A part of this effect, however, is caused by the fact that microcracking in a companion load-free specimen renders its overall shrinkage smaller than the shrinkage in an uncracked ( compressed ) specimen, thus increasing the difference between the two ( which is what defines creep ).
