American Iron Industry Development From Colonization To 1910

Published: 2014
Authors: H.J. McQueen

By 1740, American colonies blast furnaces (BFI, pig) and forges (wrought iron WI) were exporting ~1,000 t/y WI to Britain because of its charcoal shortage (until coke 1750). Although iron industry contributed greatly to success of War of Independence, British attacks left much ruined - decades to recover and adopt WI puddling (Britain 1780) with >10 fold productivity. Copious forests delayed coke use although excellent coals and direct-use anthracite.

From Ferrous Metallurgy To Materials Science: A Round Trip

Published: 2014
Authors: P. Uranga, B. Lopez and J.M. Rodriguez-Ibabe

In the framework of Ferrous Metallurgy, the 20th century saw an enormous increase in knowledge and the development of a large number of analyses and modeling techniques, some examples being physical metallurgy, phase transformations, fracture mechanics and microstructure-mechanical behavior interactions.

The Production Of Armour Plating For The Austro-Hungarian Navy By The Vitkovice Ironworks (1891-1914)

Published: 2014
Authors: Ales Materna

This study analyzes shipbuilding production by the Vitkovice Ironworks, which ranked among the most important manufacturing sectors for the company in the period 18911914. Vitkovice shifted its focus to the production of military hardware in response to increasingly tense international relations and new trends in warfare. For Vitkovice Ironworks was easiest to enter competition in the manufacture of armor plates for the construction of naval forces. This production fully met the business objectives of enterprise management, which was led from 1876 - 1893 by one of the best metallurgical experts of Austria, Paul Kupelwieser.

Effects Of The Microstructure On The Mechanical Properties Of Fully Pearlitic Eutectoid Steels

Published: 2014
Authors: J. Toribio, B. Gonzalez, J.C. Matos, F.J. Ayaso

This paper analyses how the microstructure of an eutectoid pearlitic steel affects its conventional mechanical properties (obtained by means of a standard tension test) and the associated micromechanisms of fracture. Results show how the yield stress, the ultimate tensile strength (UTS) and the ductility, increase as the continuous cooling rate rises, whereas on the other hand the strain at UTS decreases.

An Insight To The Aar Steels Task Force Projects And Initiatives To Improve Materials For Tank Car Construction

Published: 2014
Authors: Carl S. Hybinette

There have been a number of modifications to steel specifications over the last several years by the Steels Task Force of Subcommittee 1 of the Association of American Railroads (AAR) Tank Car Committee. If the steel is covered by an ASTM specification, such as A516 Gr. 70, the change is not to the ASTM specification, but rather as a special AAR requirement over and above that of the ASTM specification, while still maintaining compliance with that specification.

Hps 50W Steel (Astm A709) Applicability To Tank Car Structures

Published: 2014
Authors: Roger Sims, Tanya Ros-Yanez, William Heitmann

In a desire to improve performance of tank cars, especially in derailment situations, the Tank Car Steel Task Force of the AAR Tank Car Committee investigated the performance, formability and weldability of ASTM A709 Grade 50 (HPS 50W) as an improved steel to use in the construction of new tank cars.

Influence Of Mn-Co Spinel Coating On Oxidation Behavior Of Ferritic Ss Alloys For Sofc Interconnect Applications

Published: 2014
Authors: V. Venkatachalam, S. Molin, W. R. Kiebach, M. Chen, P.V. Hendriksen

Chromia forming ferritic stainless steels (SS) are being considered for intermediate temperature solid oxide fuel cell interconnect applications. However, protective coatings are in general needed to avoid chromium volatilization and poisoning of cathodes from chromium species. Mn-Co spinel is one of the promising candidates to prevent chromium outward diffusion, improve oxidation resistance and ensure high electrical conductivity over the lifetime of interconnects.

Determination Of The Initiation And Propagation Mechanism Of Fireside Corrosion

Published: 2014
Authors: B.S. Butz, G.R. Holcomb, G.H. Meier

Two deposit compositions were examined in short-term laboratory tests with the aim of determining rate controlling corrosion mechanisms of fireside corrosion for a range of chromia-forming alloys in oxy-combustion systems.

Optimization Of Ferritic Steel Porous Supports For Protonic Fuel Cells Working At 600┬░C

Published: 2014
Authors: V. Venkatachalam, S. Molin, M. Chen, I. Smirnov, P.O. Larsson, P.V. Hendriksen, N. Bonanos

Metal supported protonic fuel cells (PCFC) offer one major advantage over standard solid oxide fuel cells (SOFC) with oxygen conducting electrolytes, namely that the product, water, is produced on the cathode (air) side. This feature simplifies the engineering of the stack, boosts efficiency, and is particularly helpful for a porous metal supported cell because it limits the corrosion of the metal by exposure to water vapor in anode gas.
