Abstract Carburization of FeNiCr alloys leads to internal carbide formation or “metal dusting”. The appearance of these phenomena and the changes in materials properties involved are described. Under most technical conditions the alloys are protected against carburization by an oxide layer. Some carbon penetration into the alloy occurs by diffusion

Carburization - introductory survey
Materials and Corrosion, 1998This survey revisits the research in Germany in the seventies and eighties on carburization conducted in a fine cooperation of research institutes and a supplier of high temperature alloys, funded in the programme FEKKS by the BMFT. The kinetics and mechanism of the carburization of high alloy Cr-Ni-steels and the main reasons for failure were ...

Advances in Carburizing — Vacuum Carburizing
1985Steel components having appropriate combinations of wear resistance, mechanical strength, impact strength, etc., especially at higher temperatures (above 500°F) can be produced by employing the well-known conventional carburizing process or a suitably modified process.

Thermochemical treatments carried out in microwave plasma are applied to steel substrates to increasehardness and prevent corrosion and simultaneously improve wear resistance. They are efficient for steelcarburizing. Since they are electrodeless process, the steel is free from metallic sputtering.

Carburization behaviour of high temperature alloys in carburizing environment
Journal of Nuclear Materials, 1989Abstract In studying the carburization behaviour of high temperature alloys, tests in a heavily carburizing environment were performed several potential candidate alloys for use in the HTGR system. The carburization tests were carried out in Ar containing 10% CH 4 gas at 800, 850, 900 and 950 °C for up to 100 h.

Oxidation of chromium steels during carburizing in solid carburizers
Metal Science and Heat Treatment, 19761. The addition of soda to solid carburizer in place of barium carbonate leads to intercrystalline oxidation of chromium stainless steel (2Kh13) and accelerates the carburizing process. 2. At small chromium concentrations (steel ShKh15) carburizing in carburizers with soda is accompanied by internal oxidation (formation of globular ...

Abstract L'analyse du marche du petrole montre qu'il est fragile et oriente a la hausse au fur et a mesure du resserement de l'offre autour de quelques pays disposant des principales reserves. Les surproductions agricoles actuelles ne sont pas conjoncturelles. Leur transformation en gthanol est techniquement maltrisee dans des usines performantes.

Characteristic features of carburizing of steel during vacuum carburizing
Metal Science and Heat Treatment, 19791. The quantitative relationship obtained between the carbon concentration in the case and the basic parameters of the vacuum carburizing process makes it possible to determine the effective case depth for any ratio of saturation and diffusion times. 2.

Abstract Gas (atmosphere) carburizing is the de facto standard by which all other surface hardening techniques are measured and is the emphasis of this chapter. Initially, the chapter describes the process and equipment for gas carburizing. This is followed by sections discussing the processes involved in quenching, hardening, tempering,
