Using the metaphor of old, less-efficient cars compared with modern vehicles, the authors suggest that using age-old tool-steel grades may not measure up to the performance needed from modern forging die steels in certain applications.
Direct metal deposition (DMD) is a powder jet additive-manufacturing (AM) technique that can be used for low-cost build, repair, hardfacing and reconfiguration of forging dies. The technique has also been used to add features such as flanges and bosses to forged parts to improve their functionality. This article uses four case studies to examine this technique in detail and compares its merits and limitations to conventional and other AM/welding techniques.
The internal combustion engine (ICE) has been the world’s dominant form of vehicle propulsion for 100 years and counting. However, global regulatory changes focused on emissions reduction, road safety and fuel-economy improvement are increasing the potential for fully electric, zero-emissions vehicles, which will create a significant disruption to this 100-year-old technology.

Are we starting to see the signs of an “extinction-level event” as future vehicle innovation accelerates?
Researchers at Ohio University conducted a FIERF-funded inquiry to understand what cold deformation did to additive-manufactured (AM) shapes. This understanding is critical to harnessing the advantages of both processes and improving the mechanical properties of AM parts as AM technologies continue to emerge and mature.
A group of forging professionals recently gathered in Long Beach, Calif., to attend the Forging Industry Educational and Research Foundation’s (FIERF) 32nd Technical Conference. Attendees were treated to a great plant tour, two days of technology, and a chance to greet old friends and network with new ones.
Long Beach, Calif., is perhaps best known as the retirement home of the legendary cruise ship Queen Mary, which is permanently moored there and is currently an operating hotel and museum. But on Sept. 11-12, Long Beach hosted some of the forging industry’s best and brightest technical people, industry professionals, suppliers and educators at what was FIERF’s 32nd Technical Conference.
Improvements in steel manufacturing processes have yielded advancements in the purity of steel that, in turn, yield higher-quality end-use products. Clean steel is produced by judiciously controlling parameters in melting, refining, degassing and casting operations. The demand for clean steels will continue to increase due to the global push for energy efficiency and stricter CO2 emission regulations.
Steel is an amazing material when you consider its versatility. Steel can achieve the needed characteristics for a vast array of end products; it is relatively low cost compared to many other materials; it is endlessly recyclable without loss of property; and it can be mass produced, with annual global production of over 1.5 billion tons.
The sawing of bar stock into billets is one of the first steps in many forging processes, yet for some reason the bandsaw operation and equipment often do not get the attention they deserve. This article discusses how to improve your bandsaw’s operational and performance efficiency.
If there is one machine on your manufacturing floor that isn’t getting the attention it deserves, it’s most likely your bandsaw. For many forging houses, it is a bottleneck at worst and ignored at best.
The international ISO 50001 standard puts forth ambitious goals to reduce CO2 emissions and increase the generation of electricity from renewable energy sources. Energy-intensive manufacturing industries, such as forging, can reduce electricity costs and improve their competitive position through ISO 50001 certification.
