Each metals has its own blend of physical, chemical, and surface properties and characteristics. Knowing about the major work metals (not tool steels), their properties, grades, and characteristics helps to achieve the best results in stamping and forming best results.

Senior Editor Eric Lundin visited a fabricator that specializes in aircraft components, M-DOT Aerospace, to learn how the company uses warm-forming of titanium to manufacture a cradle for an auxiliary power unit, or APU. Understanding titanium's characteristics is the key in forming this durable, co...

Determining how much a metal can deform before thinning or fracture occurs is necessary for designing a reproducible forming operation. Testing the incoming sheet material is also essential because material properties may vary from coil to coil and affect the part quality and scrap rate. Understandi...

Every day Voss Aerospace faces challenges that vary as much as the materials its welders join and fabrication processes they use.

Small-diameter tubing plays a crucial role in many markets, including aerospace, nuclear, medical, and industrial. From coronary stents to hydraulic aircraft controls, each application has unique requirements. To meet the requirements of customers in these industries, well-designed processing steps ...

Welding can severely influence strengthened or hardened metals, depending on the hardening technique used. Because of this, post-weld heat treatment is often very helpful in maintaining weld joint strength because it softens or tempers any martensite or bainite that formed in the HAZ.

When it comes to modifying a steel's strength and hardness, it's important to not confuse hardness with hardenability and remember that hardenability characteristics are important because they help identify how much a specific steel will harden during welding.

Knowing how to weld dissimilar metals is becoming more and more important. One reason is that it’s often impossible for one material to provide the optimum chemical, physical, and mechanical characteristics needed for an application. For this reason, as well as cost efficiency, technology spec...

Steel classification is important in understanding what types are used in certain applications and which are used for others. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy. Steel classification systems are set up and updated freq...

When you heat or cool a piece of metal to a specific temperature, that metal goes through what’s called a phase change, in which its crystal structure changes. Sometimes the change is obvious. For example, when a piece of metal melts, it goes through a phase change when the crystal structure breaks ...

Let's start with the obvious: Molten metals have no particular structure. The atoms that make up that metal are just whipping around helter-skelter—at a high rate of speed—with no real orderly, defined pattern.

Talk about a can of worms ... From crystalline structures to phase diagrams and interstitial solutions, from microstructures to allotropic transformations, it sometimes seems that for every question metallurgy can answer, for every problem it can solve, it creates two more.
