A Failure Analysis of Hydrogen Embrittlement in Bridge Fasteners
A case study showing some of the technical issues and problems that can arise in modern steel and concrete structures, including hydrogen...
How Hot Shortness and Welding Affect Corrosion in Metals
Hot shortness is a welding defect that can cause cracking of the metal surface as it cools. These cracks can serve as breeding grounds for...
Why Understanding the Stress Concentration Factor (Kt) is Important When Evaluating Corrosion in Metal Structures
The stress concentration factor (Kt) gives a clear indication of the amount of overstress at a specified location, which is used by...
6 Ways to Prevent Corrosion Failure Analysis Frustration
This article discusses how to work with a metallurgical lab to increase the likelihood of getting the information needed to determine the...
Tensile Time Bomb: How Overtapping Compromises Pressure Bolt Safety
In the realm of high-pressure bolting, it is important to understand the dynamics and behavior of fastener systems under load, and how...
6 Tests to Measure a Material's Strength
Tensile, compressive, fatigue, torsion, nick break and creep tests are six important procedures used to measure the strength of a material.
An Introduction to Hydrogen Embrittlement
Hydrogen embrittlement is the result of the absorption of hydrogen by susceptible metals, resulting in the loss of ductility and reduction...
3 Essential Types of Material Destructive Tests
Tensile, toughness and fatigue destructive testing provides valuable information for determining the suitability of a material in a...
What is the Difference Between Strength and Toughness?
For structural components exposed to fatigue conditions, designers must be concerned with both the strength and the toughness. Find out...
What Causes Stress Corrosion Cracking In Pipelines?
Stress corrosion cracking occurs as a result of a combination of corrosion and tensile stress. Here we'll take a look at the types of SCC...
The Role of Chromium in Intergranular Corrosion
Stainless steel alloys owe their anti-corrosive properties to chromium, which grants a passivation effect to both ferrite and austenite...
An In-Depth Look at Tensile Strength
While tensile strength is by no means a sure-fire way to guarantee the reliability and safety of a structure due to many different issues,...
