Failure of Expansion Joint Caused by Corrosion Cracking

In this study, the explosion failure of a bellows expansion joint made of Type 304 stainless steel (UNS S30400) in a pipeline conducting methane (CH4) gas at 400 °C is analyzed.

MP Announces Winners of 2021 Corrosion Innovation Awards

Materials Performance (MP) magazine is proud to introduce a new class of winners from the 2021 MP Corrosion Innovation of the Year Awards program.

Systematically Making Insulation Part of the CUI Solution

Corrosion under insulation (CUI) may hinder thermal performance and lead to leaks, unexpected downtime, and repairs, while adding risk to employees and facilities. Using a systems approach to how insulation is selected and maintained can improve facility longevity and employee safety.

Stress Corrosion Cracking Susceptibility of AA7075 After Double-Peaks Aging

The stress corrosion cracking (SCC) susceptibility of 7075 aluminum alloy (AA7075) under different two-stage aging processes was studied by using the Rockwell B hardness test and slow strain rate tensile test, combined with scanning electron microscopy

Corrosion Basics: Corrosion Damage in Reinforced Concrete

The main causes of corrosion of steel in concrete are chloride attack and carbonation. Aggressive chemical species pass through the pores in the concrete and attack the steel.

Concrete Coatings for Mitigation of Embedded Rebar Corrosion

The present study experimentally investigates the effectiveness of two-component epoxy (EPX) and single-component, moisture-cure (MC) polyurethane concrete coatings in reducing the rate of chloride ingress, and thus mitigating rebar corrosion.

MIT Researchers Find Superior Way to Design Metal Alloys

The new system uses machine learning to analyze boundaries between crystal grains, which can allow for the selection of a new metal’s desired properties.

Corrosion in Braking Systems: Effect of Corrosive Environments

The characterization of corrosion scales can play a major role in both the prevention of corrosion and designing safe and reliable brakes.

Interview: Bob Chalker on the 2021 Launch of AMPP

In this exclusive interview, Bob Chalker—CEO of the new corrosion and coatings nonprofit association—discusses many of the underlying motivations that led to the Association for Materials Protection and Performance (AMPP).

A Circular Economy Approach from a Corrosion Engineer

Merging concepts like designing for purpose, maintaining with integrity, and decommissioning with a second life in mind are ideas that, if used in conjunction with adequate management tools, can help industries pursue the path of applying an effective corrosion management system.

Plans Unveiled for CORROSION 2021 Virtual Conference & Expo

The two-week event will provide a collaborative and convenient platform for corrosion and coatings industry professionals to network, learn, and develop new business.

Modeling Helps Reduce Corrosion in Refineries

Corrosion can be a significant challenge for refiners in downstream operations, and one of the key factors in causing corrosion in crude distillation unit overheads is hydrochloric acid (HCl).

Association for Materials Protection and Performance (AMPP) Is Formed

Having launched on January 6, 2021, the new organization, Association for Materials Protection and Performance (AMPP), represents a combination of NACE International and SSPC: The Society for Protective Coatings.

Some Aspects of Steam Condensate Corrosion

Diligent boiler feedwater treatment, involving mechanical deaeration and chemical treatment, is the primary defense against steam condensate corrosion. This article reviews further methods, including equipment design, materials selection, venting, reducing air ingress, and selecting steam traps.
