Abstract: | Abstract To investigate processes of producing high-quality materials using high pressures of gas VNIIMETMASH has developed 3-400 MN hot isostatic presses (HIPes) with working pressure up to 200 MPa and temperature up to 2000°C. Ar and N2 are used as working gases. Frame and vessel units of such machines are of multi-element structure which eliminates the possibility of its fragmentation failure and instant release of compressed gas energy. HIPes are intended for healing defects in casting and compacting metallic, ceramic and composite materials. |
