One Minute Mentor: Distortion in Tool Steels

Distortion in tool steels encompasses all irreversible dimensional changes. There are two main types: size distortion and shape distortion. Size distortion involves expansion or contraction in volume or linear dimensions without changes in geometrical form. Shape distortion entails changes in curvature or angular relations, as in twisting, bending, and/or nonsymmetrical changes in dimensions. In most cases both types of distortion occur during a heat-treatment operation.

Some of the main interactions occur between temperature, microstructure, and stress/strain. Especially for tool steels these interactions are mainly influenced by the carbon content in the steel matrix, the types and relative amounts of the alloying elements, and the carbide formation/transformation/precipitation characteristics of the alloy system.

One Minute Mentor: Plasma Nitriding Equipment

Cold-walled (double-walled water-cooled) systems were the first generation of plasma nitriding furnaces. This technology is also a vacuum-based process but employs the principle of glow discharge to provide energy for heating and nitriding at one time. Therefore, the independent control of the temperature stability and the nitriding intensity is not possible because both processes are using the same energy source—the plasma.

The hot-wall plasma nitriding furnaces, the next generation of cold-wall ion nitriding systems, are mainly used and built now. This system ensures optimal nitriding quality by fulfilling the highest demands on temperature and nitriding process control. The big advantage of this technology is the separation of the control of the heating and the plasma nitriding parameters.

Paragon plays key role in designing new spacesuit

Paragon, Tucson, AZ, will play a key role in the design of a new spacesuit to be worn by astronauts along with NASA and Axiom Space.

Paragon President and CEO Grant Anderson said his team is ready to be a part of the next generation of the spacesuit. He added they are already looking at all aspects of what astronauts will encounter when they are up in space.

“We’re trying to anticipate what the issues are going to be,” Anderson said. “Making it versatile, making sure it fits different sizes of people and then also fully functional on the moon.”

One of those big issues is ensuring astronauts can move and survive in a lunar dust environment. Lunar dust is so unique it can’t be found or replicated on our planet.

But Anderson said they are trying to anticipate all those issues ahead of time.

There is no set date on NASA’s plans to return to the moon. But the goal is to get there in the next couple of years.

Evolution on the microstructure and mechanical properties of a new multicomponent near-Alpha Titanium Alloy after rolling and heat treatments

Beijing University of Technology, China, presented the microstructure and mechanical properties of a new type of multi-component near-α titanium alloy sheet after rolling, 700°C aging, and 800°C aging in a new paper.

 The results show that the strength of the alloy after aging at 700°C increases from 1156 MPa to 1304 MPa, respectively, but decreases to 1246 MPa with the aging temperature increasing. The ductility of the alloy aged at 700°C is lower than that of the rolled state, but the ductility increases slightly with the aging temperature increasing. The effect of aging heat treatment on the microstructure and precipitation behavior of alloy plates has been studied and compared with alloys before aging. 

After heat treatment, the content of primary α decreases from 25% to 5%, respectively. Two kinds of silicide precipitate at different positions, with the large-size spherical silicide being (Ti, Zr, Nb)5Si3, and the small-size fusiform silicide being (Ti, Zr, Nb)6Si3, respectively. Ti3Al was precipitated in the primary α phase, during the aging process. The silicides exhibit the strengthening effect on the alloy, but the effect weakens when the silicides grow up. The loss in ductility is mainly attributed to the precipitation of the α2 phase after aging treatment. However, ductility is improved after applying higher aging temperatures as the size of the α2 phase becomes smaller, and the distribution of them tends to become dispersed.

A ‘green’ Seco/Warwick vacuum furnace for wind power plants

Seco/Warwick, Meadville, Pa., has been chosen by a recognized manufacturer of wind power plants to deliver a vertical vacuum furnace designed to perform low-pressure carburizing for the large structural elements (gearboxes) used in wind power plants. 

The solution on order combines the advantages of two technologies: atmospheric and vacuum processing. The furnace is designed for low-pressure carburizing oversized parts, made possible due to a very large, vertical heating chamber, while the furnace pit structure saves space in the production facility. The Pit-LPC technology is a modern alternative to atmosphere carburizing. Its main advantage is the ability to carry out efficient and effective carburizing in a much shorter time than in atmospheric furnaces. The vacuum processing solution provides more than twice the productivity, and consequently lower process costs and a quick investment return.

The main advantage of this furnace is the ability to open the furnace at process temperature at the end of the cycle. This is the advantage of atmospheric furnace technology implemented within a vacuum furnace. This type of solution combines the advantages of an atmospheric furnace with the advantages of a vacuum furnace, which include: elimination of the oxidation effect at the grain boundary, process purity, and heating uniformity. The product solves the problem of high energy and process gas consumption by the partner’s old furnaces, and shortens the carburizing process, which significantly improves efficiency and production costs.

One Minute Mentor: Salt Bath Nitrocarburizing

Salt bath nitrocarburizing is usually performed at temperatures between 560 and 580 °C (1040 to 1075 °F) in cyanate- and carbonate-containing salts with traces of cyanides and furnaces similar to those used for the nitrocarburizing of mechanical compounds. These conditions fit well with the usual tempering temperatures of hot-work tool steels, which form the main field of application of salt bath nitrocarburizing in tooling with treatment times of 15 min to 2 h.

 To guarantee a good reproducible nitriding performance, the cyanate content must be kept at approximately 35% to achieve a full ε-nitride compound layer, which today is usually done by adding a regenerator. The advantages of salt bath nitrocarburizing can be found in the very homogeneous temperature distribution, the fast formation of thick compound layers that give good tribological and corrosion properties, its high flexibility, and he fact that it does not require that any special attention be given to passivation effects. Extrusion dies are regularly treated several times during use to restore the nitride layer at areas of heavy wear.

More recently special salt compositions were developed for lower nitrocarburizing temperatures, which are essential for cold-work tool steels that do have lower tempering temperatures.

One Minute Mentor: Vacuum Furnaces

The demands on vacuum-hardening technology have changed in recent decades. One of the most important considerations that must be met is the accomplishment of highest dimensional stability with optimal microstructural properties and minimal change of the surface of the workpieces. 

Minimizing exposure to air during the heat treatment by reducing the quantity of oxygen in a heat treatment furnace, as with creating a vacuum, is an excellent method for preventing changes in surface appearance and chemical composition.

Suppliers of modern vacuum furnaces are further faced with new demands, such as increasing quenching speed to improve microstructural and mechanical properties by reducing grain size, and enhancing hardness and toughness and/or reducing distortion due to the hardening process. Furthermore, quality standards such as AMS 2750d or North American Die Casting Association (NADCA), which describe temperature homogeneity or quenching speeds and resulting and needed workpiece properties, had a significant effect on furnace design and process control.

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.
