High hot hardness
WebHigh velocity sintering processes can minimize grain growth and manufacture a harder sintered compact with a high relative density of 99–100% and a hardness of over 20 GPa. Pressurized sintering allows for the direct sintering from powders to near-net shape dimensions of a ring or cylindrical shape, and eliminating the green body compaction …
