Abstract
The work described is concerned with the development of vacuum-sintered ferrous materials that can be used for high-strength structural parts. The reasons for choosing this production route are given, and the development of the materials is traced from the simple iron–carbon alloys to the more complex iron–carbon–nickel–chromium alloys. The metallography of the various series of alloys is included and the mechanical properties are fully reported. Tensile strengths > 70 tons in −2 were obtained after heat-treatment. An indication of the dimensional changes that took place during sintering is also given.
