The hardness testing is performed using the Rockwell hardness test with the diamond indenter and the D-scale. As the investigation and statistical analysis is done in this experimental study, the verification of size and shape were affecting the hardness of steel is identified. ...
Conventional MA steels typically have a grain size of about 8–12μm. Nowadays, ultrafine-grained steels can be obtained by using various fabrication routes, both in the laboratory and on the industrial scale. The routes can be divided into two major groups, namely: ...

and other cutting tools. These steels generally exhibit a hard martensite matrix with dispersedcarbidesthat provide excellent wear resistance and hardness. Although several tool steels are used,H13 tool steelis the most common inadditive manufacturing. We have focused on H13 tool steel in this review...

10mm×5mm [72]. The schematic is shown inFigure 4.4.10. It is seen that the corrosive chlorine is recycled in a process within a closed loop. An evaluation on the basis of pilot tests with treatment scale of 1,000,000ton per year showed that the technology is also economically ...
In addition, we also investigate the hardness at different positions on the surface of HW, as presented in Figure S3, which shows only a modest variation (Figure S4) and thus suggests a rather uniform hardness of the HW. The dependence of HW hardness on the chemical treatment time can be ...
