Sentence examples for hardened zone from inspiring English sources

The influence of laser temporal pulse shape on connectivity of hardened zone, maximum surface temperature of material and hardening depth is numerically investigated at different pulse energy levels.

This results in less internal stress and, most important, a deeper hardened zone in the workpiece.

This tensile stress peak is located in the transition zone between the hardened zone and the core material.

Different laser parameters were compared and their influence on hardness, microstructure, geometry of the hardened zone and sensitisation was investigated, especially for overlapping passes.

Third, punching operations are responsible for the introduction of a plastically hardened zone which, according to both micro-hardness measurements and diffraction data, is about 200 μm deep.

Test samples were also annealed up to 620 °C to vary the hardness of the laser hardened zone.

The residual stress distributed within the melt-hardened zone is always of the compressive type.

The effects of the case-hardened zone, quasi-static strain rate and the crush force efficiency were investigated.

It greatly affects the mechanical properties in the melt-hardened zone with its volumetric expansion effect and the hardness increases by 2 3 times.

The data support the model, presented earlier, which proposes that defects, including dislocations, are generated in the surface by the implantation process and lead to the development of a work-hardened zone below the surface that enhances wear resistance.

With the increase of the laser power from 3000 to 3800 W, the width and the depth of the laser melted layer increase, while the laser power has a little effect on the martensite contents, which exceed 90% in the melt-hardened zone.
