One Minute Mentor: Distortion in Tool Steels

To control the distortion that occurs both during and after heat treatment, proper consideration must be given to such factors as design, composition, initial condition, machining procedure, and heat treatment. The design of a tool-steel part directly affects the susceptibility to shape distortion on heating and cooling. Limitations imposed by the design on composition, machining procedure, and heat treatment may indirectly affect both shape and size distortion.  The figure shows the expected magnitude of shape distortion for this range of sizes. The difficulty involved in economically attaining the final dimensions of a part is largely determined by the magnitudes of the specified tolerance limits.

Norman Noble receives NTMA Superior Safety award for second consecutive year

Norman Noble, Highland Heights, Ohio, has been honored with the National Tooling & Machining Association’s (NTMA) 2024 Superior Safety Award for the second year in a row. The accolade recognizes member firms achieving exceptional workplace safety performance, and Norman Noble earned this distinction by keeping its incident rate well below the industry average across all advanced manufacturing sites.

The company uses a daily management system to track key performance indicators—such as lost-time claims, recordable injuries, first-aid incidents, near misses, days of restricted work activity, and streaks without a lost-time claim—to monitor progress toward its health, safety and environmental objectives. Julie Bennett Lowry, director of facilities and environmental health and safety, explained that integrating safety observations into daily gemba walks and immediately logging any issues ensures rapid follow-up. Thanks to this proactive process, the firm recorded zero lost-time claims in 2024 and, as of May 1, 2025, has surpassed 1092 consecutive days without a lost-time incident.

Operating over 275,000 square feet of manufacturing space with more than 500 employees, Norman Noble produces precision components for life-saving medical vascular and orthopedic implants. The company said its continued focus on safety underpins both employee well-being and its commitment to maintaining rigorous quality standards.

One Minute Mentor: Improving the Homogeneity of the Distortion Behavior

Controlling out-of-roundness is important for certain precision applications, such as class C and D cutting hobs made of high-speed steels. Class C and D hobs must be held close to size limits because they are not ground to size after heat treatment, but rather are used in the unground condition.

Normal size distortion in hardening and tempering can be accommodated by making the tool slightly oversize or slightly undersize, as required, before heat treating. High-speed steel bars, however, have been observed to go out-of-round as much as 0.05 mm (0.002 in.) during heat treatment. The pattern of size distortion shown in Fig. 8 can occur. It appears to be related to the initial shape of the cast ingot and to the specific primary-mill processing used to reduce the ingot into bars.

One Minute Mentor: Process Control in Nitriding Systems

Modern gas nitriding and nitrocarburizing furnaces are equipped with sensor systems and a process control unit that allow the measurement and automatic control of the nitriding potential (KN). The figure shows an example of how the process control can be carried out. 

Defined amounts of ammonia, nitrogen, and—for nitrocarburizing processes—carbon dioxide, can be chosen for each step in the program and fed into the furnace via mass flow controllers. The gas composition in the retort is measured via a nitriding probe. For the measurement of nitrocarburizing processes two different probes are needed. The control unit calculates the nitriding potential according to the measured values and controls the mass flow of ammonia to meet the requested set point of KN. During the nitriding process the gasifying amount of ammonia can just be reduced to a certain limit. To keep the KN value low, therefore, precracked ammonia must be added. It must be mentioned that there are some more simple control systems available, which also produce good results.

Researchers overcome manufacturing challenges in aluminum alloys with nano-treatment

Researchers at the University of California, Los Angeles, have achieved a significant breakthrough in the field of metal additive manufacturing (AM), specifically with Al–Cu alloys like AA2024, which are prevalent in the aerospace and automotive industries. 

These alloys are known for their high strength and good fatigue resistance but have been notoriously difficult to work with in additive manufacturing due to issues like hot cracking and other solidification defects.

The UCLA team has successfully developed a nano-treated AA2024 deposition that incorporates TiC nanoparticles, leading to a groundbreaking enhancement in the manufacturing process. This new method allows for the additive manufacturing of AA2024 without the occurrence of cracks, a common issue that has hindered broader adoption of these materials in high-precision sectors.

Microstructural analysis conducted by the researchers reveals that the TiC nanoparticles not only reduce the susceptibility to hot cracking but also refine and homogenize the grain structure of the alloy. The grains were significantly refined to an average size of 23.2 ± 0.4 μm. This refinement contributes to the material’s enhanced properties, including its mechanical performance.

These findings highlight the potential of nano-treatment techniques in overcoming the longstanding challenges associated with high-strength aluminum in additive manufacturing. This advancement not only paves the way for more reliable production of critical components in aerospace and automotive applications but also promises to expand the capabilities and applications of metal additive manufacturing technology.

One Minute Mentor: Salt Bath Nitrocarburizing Equipment

Modern salt bath nitrocarburizing units can be arranged as fully automated and contained lines and usually consist of an air-preheating furnace, one or several salt bath nitrocarburizing furnaces, which can either be heated electrically or by gas combustion, and a cooling unit that can be an oxidizing salt bath. Such oxidizing posttreatment builds up a thin and dense oxide layer on top of the compound layer that significantly increases the corrosion resistance. 

Online monitoring of the chemical composition is not required due to the high stability of the melt and the automatic supply of refill salt and regenerators. The nitrocarburizing line usually ends with three- to four-step washing cascades that also act as a regeneration system for the salt.

Gas nitriding and nitrocarburizing is the most sensitive process regarding passivation effects typical for medium- to high-alloy tool steels. Therefore special attention must be paid to cleaning and pretreatment processes such as preoxidation, controlled oxinitriding, or the use of chemicals such as hydrazine. On the other hand, gas processes have the best accessibility for boreholes and thin gaps.

One Minute Mentor: Continuous Operating Furnaces for Tool Steel Strips

The continuous heat treatment of tool steel is applied to low- or medium-alloyed carbon steel strips as well as martensitic stainless steels. The described lines produce high-quality strip with respect to uniform structure, flatness, and bright surface finish. Steel grades with 0.4 to 1.2% C, low and high alloyed, can be processed. Strip dimensions range between 10 to 750 mm (0.4 to 29.5 in.) wide and 0.05 to 4 mm (0.002 to 0.16 in.) thick. High quenching rates are necessary, especially for plain carbon steels. Cooling gradients of up to 600 K/s are possible in a molten lead-bismuth quench. Because two-stage quenching technology provides considerable advantages over quenching in oil, this method has been adopted worldwide. It is also possible to achieve isothermal transformation to bainite and pearlite using a molten metal quench, so this type of hardening and tempering line is extremely versatile.

The configuration of a high-performance line involves an entry and exit section of the strip handling equipment (Fig. 10). The hardening section consists of the austenitizing furnace, the molten metal quench or hydrogen quench, and a martensite cooler. Beyond the martensite cooler the strip is martensitic and fully hardened, and then it passes through the tempering section—consisting of a leveling furnace, tempering furnace equipped with an atmosphere recirculation system, and an atmosphere jet cooler—to finally leave the facility, completely flat, with a bright surface finish and tempered to very uniform tensile strength.
