Seco Warwick, Meadville, Pa., introduces its Super IQ integral quench furnace and UCM 4D Quench system.
The Super IQ (integral or sealed quench furnace), offers all of the benefits of low pressure carburizing and vacuum hardening, with none of the added costs. The system combines clean processing with the exceptional performance of oil quenching in the industry’s most innovative integral quench furnace design in decades. With a Super IQ, users get super clean parts while still getting the benefit of a simple atmosphere oil quench.
The UCM 4D Quench enables customers with gas quenchable materials to replace oil quenching with an environmentally friendly, cost-effective technology. It provides a solution that eliminates the need for press quenching systems and the problems associated with their operation. First, no more finishing treatment is needed to remove the oxidized layer. Second, it provides parts with higher surface quality and savings due to eliminating the need for heat treatment fixtures and material logistics. Third, it eliminates oil and oil vapor contamination, ensuring personnel safety and reduced environmental impact in addition to eliminating washers and chemicals.

Solar Atmospheres of Western PA, Hermitage, recently installed a 14-foot long car bottom air furnace for the tempering of large tool steel components, as well as the age hardening processes of nickel-based alloys and precipitation hardenable stainless steels.
The furnace was surveyed in accordance with AMS2750 Rev E and is uniform within ±10°F (Class 2). With a working zone measuring 60 x 54 x 168 inches, the furnace is capable of handling workloads up to 30,000 pounds and feataures maximum operating temperature of 1400°F.
According to Bob Hill, President of Solar Atmospheres of Western PA, “This new air tempering furnace will be a good complement its larger counterpart, a recently installed 20-foot car bottom furnace. Expanding our large air furnace capability will enhance the turnaround for our ’raw material’ customers, and is more cost-effective than processing in a vacuum environment.â€

One Minute Mentor: Martensitic heat treating
June 12, 2019
Source:
The graph shows the tempering response of hardened 52100 bearing steel. In North America, the 1C-1.5Cr through-hardening steel was given the designation of 52100. One of the main reasons this steel became popular as a bearing steel is its consistent response to salt-bath and furnace heat treatment and oil quenching (assuming the incoming raw material conditions met hardness, microstructure, and grain size specifications).
The standard heat treating cycle for martensitic hardening of 52100 bearing steel is:
Austenitize 815–855C (1500–1570F) 15–40 min + 30 min for each additional inch of thickness, endo or neutral atm with 0.9–1 C potential;
Quench ≤150C (300F) agitated oil (martensitic hardening); ≥230C (445F) molten salt (bainitic hardening)
Temper 150–230C (300–445F) 2–4 h (58–64 HRC).
As-quenched hardness after heat treating is typically 64–67 HRC. Figure 1 shows hardness as a function of tempering temperature.
The goal of tempering 52100 bearing steel is to achieve a measure of toughness in the steel while maintaining high as-tempered hardness. A bearing must have a minimum hardness of 58 HRC to achieve the expected rolling contact fatigue performance in service. This requirement dictates a maximum tempering temperature of 260°C (500°F).
Another goal of tempering bearing steels is to achieve the required level of dimensional stability as described in specification DIN-623. This topic is discussed more thoroughly in an upcoming section.

ITSC 2019 presentation: Solid-State Additive Manufacturing
June 11, 2019
Source:
Inovati, Santa Barbara, Calif., presented a discussion about the application of its impact consolidation Kinetic Metallization (KM) process to an advanced and superior 3D manufacturing technology.
When integrated with CAD/CAM, Inovati characterizes this new technology as Solid-State Additive Manufacturing (SSAM). This innovative spray deposition process provides unique opportunities for development of a 3D fabrication technique with material properties not currently feasible with conventional fusion-based AM processes.
In particular, the low temperature attribute of the process enables fabrication of metallic and composite parts with metallurgically uniform properties, while fusion-based processes tend to be unstable or degrade at high melting temperatures. The SSAM deposition rates associated with Kinetic Metallization permit an order of magnitude faster fabrication rate of parts when compared to many conventional AM methods. The paper presented the developments of the technology to date and the potential applications.

Sintavia LLC, Hollywood, Fla., has opened the doors to its new 55,000-square-foot advanced manufacturing facility, which is said to be the first of its kind in North America to offer large-scale AM production coupled with a robust aerospace quality management system.
The facility houses over $25 million of advanced manufacturing equipment, including medium and large scale metal printers, EDMs, post-processing machines, wet-booths, and multiple furnaces. Some of the industrial engineering improvements of the building include separate manufacturing rooms segregated by alloy, a large-scale powder management system, an uninterruptable power supply, an inert gas farm, and a final production acceptance quality-control room.
The new facility is capable of producing tens of thousands of parts representing in excess of $100mm of AM revenue annually. The expansion is anticipated to bring more than 130 new jobs for skilled employees and support staff to South Florida.
“As we grow, it will serve as a template for future vertically aligned advanced manufacturing facilities around the United Staets and the world,†said Brian Neff, Sintavia’s Chairman and Chief Executive Officer.
The grand opening was attended by over 150 customers and industry partners, including Sumitomo Corporation, a growth equity investment partner of Sintavia and one of the largest international trading companies in the world. “Sintavia has again proven itself as a leader in the industrialization of AM production,†said Mr. Masaki Nakajima, CEO and President of Sumitomo Corporation of Americas.

Russian scientists dope aluminum with nickel and lanthanum to raise strength and ductility
Source:
Scientists from the National University of Science and Technology (MISIS), Russia, report that they have found a simple and efficient way of strengthening aluminum-based composite materials. Doping aluminum melt with nickel and lanthanum, scientists managed to create a material combining benefits of both composite materials and standard alloys: flexibility, strength, and lightness.
Scientists from NUST MISIS scientific school "Phase Transitions and Development of Non-Ferrous Alloys" created a new strong Al-Ni-La composite for aircraft and automobile industry. Doping elements were added to the aluminum melt, forming special chemical compounds that further formed strong reinforcing structure.
"Our research group, led by Professor Nikolai Belov, has worked on the creation of aluminum-based composites for many years,†says Torgom Akopyan, a researcher at NUST MISIS Department of Metal Forming. “The aluminum-based composite material contains more than 15% by volume of doping elements. A feature of the new development is the high reinforcing ability of the chemical compounds with ultrafine structure: the diameter of the reinforcing elements does not exceed several tens of nanometers.â€
This development solves the problem of non-uniform reinforcement and low density of "powder" composites: if a melting technique is used, after Al-Ni-La crystallization the diameter of doping particles does not exceed 30-70 nanometers. Thanks to "natural" crystallization, particles are distributed uniformly, forming a reinforcing structure. Hence, the composite becomes stronger and more flexible than its powder analogues.
Due to the peculiarities of the structure formation, the proposed material can be used for the manufacture of complex parts via 3-D printing. In addition, new developments may be of strategic importance from an economic point of view. At the moment, the main share of profit in the aluminum industry in Russia is the export of primary aluminum. The creation of new high-tech developments with increased added value will increase profits by expanding domestic and foreign markets for aluminum consumption.
An article on the research was published in Materials Letters. T.K. Akopyan et al, “New in-situ Al matrix composites based on Al-Ni-La eutectic,†Materials Letters (2019). DOI: 10.1016/j.matlet.2019.02.112
