microcracks

Under the same externally applied stress, the volume fraction of the microcracks increases with that of the constituents.

In this work, the surface microcracks machined by powder-mixed EDM were researched.

Minimal the tendency of microcracks can be obtained by improving the shape of weld pool and enhancing the welding energy input.

The damage of cancellous bone mainly depended on the damage of trabecular bone and distribution of the microcracks on trabecular bone.

The results show that the gel still has a great fluid loss in the microcracks of microfracture developed reservoirs.

Results showed that except some oxidation eroding pits and microcracks, the surfaces of specimens haven't undergone visible damage.

The microcracks can be caused by friction , mechanical treatment, thermoelastic forces, etc.

In addition, microcracks generated at inclusions and grain boundaries, and merged to crack at the condition of stress concentration.

But some cracks, called "microcracks, " areso small that even an experienced human grader's eye can miss them at theprocessing plant.

The course of persistent slip bands and the formation of microcracks were investigated.

Many of the eggs were manipulated to cause microcracks and wereimmediately examined by AMS graders and scored as either intact or cracked.

Defects of the first kind are microcracks caused by surface damage to the finished product .

Unfortunately, the microcracks grow over time and are ofteneasily visible by the time they reach consumers at market.

There are also some micropores and microcracks in the reflowed alloy.

conducts and envelops oil and gas, small faults and microcracks conduct oil and gas, form pool of sandstone lens in sub-depression;
