    This work investigates the behaviour of nitrogen in steel melts with a wide range of carbon content in oxygen converters and electric furnace production. It determines the main ideas of low nitrogen steel technology. 1. Thermodynamics and kinetics of nitrogen absorption and extraction. Solubility of nitrogen in iron is subject to Sivert’s law.

    This authoritative account covers the entire spectrum from iron ore to finished steel. It begins by tracing the history of iron and steel production, right from the earlier days to today’s world of oxygen steelmaking, electric steelmaking, secondary steelmaking and continuous casting. The physicochemical fundamental concepts of chemical equilibrium, activity-composition relationships, and 4/5(5). high carbon steel is easier than that of low carbon steel. Similarly, Si, Ni and Cu decrease the solubility of nitrogen in steel. On the other hand, V, Cr, Mn, Mo and W increase the solubility on nitrogen in steel. Vanadium has a significant effect on solubility, whereas effect of W is Cited by: 6.

Jap., 64 (), pp. 97– Google ScholarCited by:   Iron-nickel alloys with 8 and 16 wt pct nickel and iron-chromium-nickel alloys with 8 pct nickel and chromium contents in the range of 2 to 22 pct were equilibrated with iron and nickel in flowing CH4-H2 gas mixtures and in sealed capsules under partial vacuum at temperatures between and °C.

Carbon activities in these alloys were established from the carbon concentrations in the Cited by: The investigation on the transformation of austenite to martensite based on the statistical thermodynamics was carried out using the iron-nitrogen binary alloys containing about to weight per cent nitrogen.

The result of this treatment was compared with that of the iron-carbon binary by: 6. Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on high-carbon, low-alloy steels.

They are also used on medium and high-carbon steels, titanium, aluminium andnitriding was used to generate unique duplex microstructure (Martensite-Austenite, Austenite-ferrite.

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5, opes: graphite, diamond, others.

Rawers. I want to retrieve cryotubes from the bottom of a liquid nitrogen freezer without taking all the freezer racks out and draining the liquid nitrogen. I think I can accomplish this using a tool like this but I am not sure how well the tool will function at temperatures as low as Celsius.

Tschiptschin Metallurgical and Materials Engineering Department University of SZo Paulo Av. Pro$ Mello Moraes n ‘, Si70Paulo – SP, Brazil ABSTRACT Nitrogen improves wear and corrosion resistance of martensitic stainless steels.

The steelmaking field has been seeing an increased demand of reducing hydrogen and nitrogen in liquid steel before casting. This is often accomplished by vacuum treatment. This paper focuses on developing a numerical model to investigate the removal of hydrogen and nitrogen from the melt of medium carbon steel in a commercial vacuum tank by: 7.

In the electric arc furnace (EAF), and the basic oxygen furnace (BOF) for producing steel, the major off gas is carbon monoxide (CO). If the CO can be combusted to CO{sub 2}, and the energy transferred to the metal, this reaction will reduce the energy consumed in the EAF and allow for more scrap melting in the BOF which would significantly lower the energy required to produce steel.

PALMER Oliver Springs Tennessee TN Combining modern thermodynamics theory branches, including finite time thermodynamics or entropy generation minimization, constructal theory and entransy theory, with metallurgical process engineering, this paper provides a new exploration on generalized thermodynamic optimization theory for iron and steel production processes.

The theoretical core is to thermodynamically optimize performances Cited by: Developing new steels is one of the most important driving forces for advancements in construction, medicine and the automotive industry.

A promising approach is to add nitrogen. In conventional steel processing, nitrogen alloying is challenging due to its limited solubility during casting and solidification.

Base on thermodynamics, the nitrogen concentration and nitride phase constitution at the surface of the nitrided case are determined by the temperature and nitriding potential.
