Tooling materials science| Zusammenfassung: | The aim of the work is to determine the influence of the physico-mechanical properties of the material of the punches on the level of the generated pressure in the six-punch cubic apparatus and the limit state of the punches. Computer modeling using the finite element method of compression of a pyrophyllite container between punches made of tungsten-cobalt hard alloys VK6, NF, HB02UF and KF308 has been carried out, and the stress-strain and limit states of the container and punches in the process of deformation have been investigated. It is recommended to use punches from foreign alloys KF308, HB02UF and NF, which ensure the strength of the apparatus at a pressure of 5–7 GPa. |
