A recent advance in corrosion-resistance technology overcomes the problem of steel corrosion in CO2enriched environments. At an inhibitor concentration of 10 M, the inhibition efficiency exceeded 98% where the steel corrosion rate is decreased by a factor of at least 100.

In the paper we rewiev the experience with the steel from Cold Rolling Mill Kraluv Dvur near Prague, where the steel for barrel module 0 prototype of the TILECAL calorimeter was fabricated. The measurements of the tolerances, mechanical properties and the chemical composition are presented.

The justification and economics of the operational animal damage control program in California as conducted by the U.S. Fish and Wildlife Service are discussed. Emphasis is given to the necessity for use of the steel trap. Nearly 83 percent of the depredators are taken by trapping. Annual agricultural losses due to predation were estimated at $4.7 million in California for Fiscal Year 1975. The...

Frettingwear between a hemisphere and a flat plate is investigated experimentally and the effect of laser polishing is studied.

According to the direct homogenization theory of inhomogeneous material, a single medium homogenization constitutive model of the confined concrete in the steel box-concrete combined member has been established, and model parameters have been determined by the measured data of the bending test. By analyzing the theoretical ultimate strength and overall process curve, the results obtained is con...

This paper examines a few methods used in grounding analysis and illustrates the advantages, limitations, and the applicability of these methods. Computation results using these methods are presented and compared. The various cases modeled in this paper include grounding networks of different sizes, grounding networks with buried metallic structures such as steel pipes, and high frequency cases...

This study sums up the authors recent works on steel Non-Destructive Testing and Evaluation achieved between 2000 and 2008. The main related items are the establishment of a first-order correlation between the thermal diffusivity and the Vickers hardness HV as a guide to set an NDT protocol to investigate steel strengthened surface performance. A special attention is confined toward carburized ...

This paper presents an analysis of water modeling of steel pouring to study (1) air entrainment and (2) filter effectiveness to remove reoxidation inclusions. In the first part, a review is presented of the physical processes and parameters important in air entrainment in free-surface flows. Then, the use of a water system to model air entrainment in steel pouring is analyzed. Attention is focu...

This paper presents a series of tests on cold-formed stainless steel bolted connections. The test specimens were fabricated from three different types of stainless steel, including austenitic stainless steel EN1.4301 (AISI 304) and EN1.4571 (AISI 316Ti having small amount of titanium) as well as lean duplex stainless steel EN1.4162 (AISI S32101). The material properties of the three types of st...
