One Minute Mentor: Type W1 Tool Steels

W1 steels are capable of hardening to high surface hardness and soft core, which is useful in some shock applications. They are low-cost tool steels with fair to good wear resistance as carbon content increases. As they are water quenched and have poor dimensional stability, their use is limited to fairly uniform sections with a minimum amount of stress risers; in other applications quench cracking can occur. Figure 1 shows an isothermal transformation diagram for a W1 steel.

Seco/Warwick Partners with European Defense Sector Manufacturer

Seco/Warwick, Swiebodzin, Poland, announced its first contract with a European defense manufacturer. The company will deliver a customized single-chamber vacuum furnace equipped with advanced low-pressure carburizing technology and high-pressure gas quenching for heat treatment of steels used in firearm manufacturing.

The contract represents a shift by the defense client from traditional gas carburizing to modern low-pressure carburizing, which improves quality, process predictability, and energy efficiency. The vacuum furnace approach eliminates the environmental concerns associated with atmosphere-based systems while delivering more uniform case depth and reduced distortion.

The deal holds strategic significance for both parties. For the client, it represents a modernization of defense manufacturing infrastructure. For Seco/Warwick, it establishes a position as a solutions provider in the European defense sector, a market segment with growing demand for advanced thermal processing equipment.

Seco/Warwick operates globally with manufacturing facilities in Poland, the United States, India, and China, and service centers across Europe and Asia.

One Minute Mentor: Advantages and Limitations of Heat Treatment Simulation

Heat treatment simulation can be a tool for optimization of heat-treatment processes, but at the present this method is still limited. Therefore most HTS is based on rough simplifications of the process. Simplifications can involve the process, number of phases, transformation kinetics, continuums models instead of micro-mechanical models, etc. These simplifications also result in inaccuracies in the calculations.

Constellium announces significant weight savings in EV Battery enclosures through ALIVE project

Constellium, based in Paris, announced that its collaborative research project, Aluminium Intensive Vehicle Enclosures (ALIVE), has achieved weight savings of 12 to 35 percent for electric vehicle (EV) battery enclosures. The project, led by Constellium’s University Technology Center at Brunel University London, focused on optimizing the design and manufacturing processes for structural aluminum enclosures in EVs.

Launched in 2020, the £15 million initiative was partially funded by the UK government through the Advanced Propulsion Centre (APC). The project involved six industrial partners, including BMW, Volvo, and Innoval Technology, along with university technology partners from Brunel University London and the University of Warwick.

The ALIVE team developed new aluminum designs using Constellium’s high-strength alloys, HSA6® and HCA6®, while implementing advanced joining and forming technologies. Full-scale prototypes were produced and successfully passed rigorous testing for performance, safety, and fire resistance. The project also generated cost models to support future industrialization of the designs.
