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,

Carburizing: Microstructures and Properties explains how to recognize and address problems associated with case carburizing treatments for steels. It examines the nature of internal oxidation, decarburization, free carbides, and retained austenite and their effect on fatigue and fracture strength, wear resistance, impact toughness, hardness, and other ...

Abstract Pack carburizing is a process in which carbon monoxide derived from a solid compound decomposes at the metal surface into nascent carbon and carbon dioxide. In addition to discussing the pros and cons of pack carburizing, this article provides information on the carburizing medium, compounds, furnaces, and containers used in ...
