The Defense Logistics Agency is the Department of Defense’s largest logistics combat support agency. It supplies 84% of the military’s spare parts and provided $44 billion in sales and revenue in fiscal 2012. Want to learn how to become a part of this program and gain sales by supplying forgings for defense and weapon systems? Just keep reading.
Additive manufacturing techniques are no longer in their infancy. They are quickly emerging into serious options for the production of metallic parts. Forge shops should keep a watchful eye on this unfolding technology, both as a competitor and as an opportunity.
is the main constituent in titanium alloys, of course, but they can contain a
significant amount of other elements, which are added for a variety of
metallurgical reasons. The strength of titanium alloys can often be comparable
to steel, but they have the advantage of having only about 60% of the weight.
This article introduces a practical technique pioneered by a metallurgist at the Indian Institute of Technology. The technique enables any kind of steel to be heated without the problems associated with oxidation and decarburization.
This article continues FORGE’s series on forging
materials. The first installment on nonferrous forging materials discusses
aluminum alloys that are used in forged components. A general description of
aluminum alloys is followed by details of their chemistry and microstructure.
The rolling and thermal treatment of forged
rings sometimes leaves residual stresses that cause dimensional distortion.
Corrective measures in industry are often based on trial-and-error techniques.
Ongoing research seeks to base corrective actions on the laws of physics.
Like all steels,
microalloyed steels are iron-based metal alloys. Normally, they are plain
carbon or low-alloy steel with small additions of one of
three special elements. These steels were developed in the 1960s and used for
plate and pipeline applications. It was not until the 1980s, however, that
forgers began to produce microalloyed steel components in significant
