Sentence examples for hardened regions from inspiring English sources

A cyclic bending experiment is designed to investigate the interface fracture behaviour of a hard chromium coating on a ductile substrate with periodic surface hardened regions.

Hardened regions in both samples with the depth of ~170 μm beneath the coatings, are attributed to the quenching effect of the substrate, make the hardness drop eventually from the coating to the substrate.

These maps revealed regions of considerable material hardening inside the plastic zone and softening of material outside the hardened region.

Moreover, the periodical gradient morphologies of the LDQS substrate are clearly shown: the surfaces of laser transformation-hardened regions are rather smooth; a lot of fine micro-holes exist in the transition zones; there are many micro-dimples in the original substrate.

Mechanism 1 is not active at 300 °C because the strain-hardened regions will rapidly relax.

The presence of strain-hardened regions built up in the Al matrix at the interface with the aluminides and the eutectic + primary Si.

The strengthening mechanisms responsible for the strength of the investigated AlSi10Cu5Ni1-2 areoys are: (1) The presence of strain-hardened regions built up in the Al matrix at the interface with the aluminides and the eutectic + primary Si.

The expansion of the loops and their cross slip leads to the severely work-hardened region surrounding a growing void.

Such knowledge of the plastic response of the case hardened region will help optimize the design of case hardened bearings with longer rolling contact fatigue life and higher thrust load capabilities.

The study suggests that the nanocrystalline surface layer and work-hardened surface region play a significant role in enhancing the fatigue limit of the SNH-processed nickel alloy.

The contributions of the nanocrystalline surface layer and work-hardened surface region have been separated from that of residual compressive stresses.
