Alcoa Corp., Pittsburgh, announces plans to restart three of five potlines at its Warrick Operations aluminum smelter near Evansville, Indiana, an action that will further improve the competitiveness of the on-site rolling mill.

The process to restart the three lines, with 161,400 metric tons of annual capacity, will begin immediately and is expected to be complete in the second quarter of 2018. The three potlines will directly supply the Warrick rolling mill, which serves the North American market with flat-rolled aluminum for the food and beverage can packaging industry. The smelter's molten metal will supplement purchased scrap metal and other raw materials that the Warrick site will continue to procure.

"By restarting a portion of the Warrick smelter, we will provide an efficient source of metal for the co-located rolling mill and help it meet an anticipated increase in production volumes," said Tim Reyes, President of Alcoa's Aluminum business unit. "The action will enable us to more fully utilize the assets at this integrated site."

The smelter at Warrick closed in March of 2016. Two of the five smelting potlines will be classified as curtailed capacity and will remain idle. After this partial restart, Alcoa will have approximately 886,000 metric tons idled of its total smelting capacity of 3.4 million metric tons.

Alcoa Warrick Operations is comprised of the smelter and the rolling operations, which includes state-of-the-art casting, hot and cold rolling, slitting and coating capabilities. The operations also include the power supply for the smelter and rolling operations, consisting of a coal mine that fuels four generating units with a combined net capacity of about 750 megawatts. Three of those units are wholly-owned by Alcoa Power Generating Inc. A fourth unit, Warrick Unit 4, with 300 megawatts of net capacity, is owned in a 50-50 partnership with Vectren, a utility headquartered in Evansville.

Wisconsin Oven Corp., East Troy, Wis., has shipped two steam-heated batch ovens to a leading manufacturer of industrial products for curing a water-based adhesive applied to rolls of sandpaper. The adhesive is needed for the sand to stick to the paper, and curing the adhesive provides for a more durable product. These ovens are a duplicate of a previous order, and were needed to meet increased production demands.

The curing ovens have a maximum operating temperature of 300°F and work chamber dimensions of 17.5x21.3x7.5 feet. The customer required temperature uniformity of ±5°F at 240°F for each batch oven, with uniformity verified by a twenty-point profile test. These ovens have sufficient capability to heat 35,000 pounds of product from 70°F to 240°F within two hours, and cool the load down to 140°F within three hours.

These batch ovens feature top-down airflow that is distributed through the work chamber by factory preset nozzles. Jumbo suction fans draw hot air through all the layers of the sandpaper rolls. The airflow arrangement provides optimum air flow efficiencies along with maximizing heating rates and temperature uniformity.

"At Wisconsin Oven, we pride ourselves on new and innovative designs," says Tom Trueman, Application Engineer. "For this project, large suction fans were used in the design to ensure that the hot air was drawing through all layers of the roll for a uniform cure of the adhesive."

Russian scientists develop strong shape memory alloy based on Fe-Ni-Co-Al

November 7, 2016
Source:

The Tomsk University Laboratory for Physics of High-Strength Crystals, Russia, announces that its researchers have designed a new high-strength iron-base shape-memory alloy whose properties are developed through a heat treatment technology that they have patented. "We especially use iron-nickel-cobalt-aluminum, plus a fifth element that could be titanium, niobium, or tantalum," says Prof. Yury Chumlyakov, head of the laboratory. "These alloys can compete with nickel titanium."

In particular, the researchers claim that the alloys have a reversible change in shape of about 15%, while nickel-titanium alloys have about 10%. Thus, the sensors and actuators made of the alloys would work more effectively. The iron-base alloys are also said to have high strength, important for practical use in devices that must withstand high external loads, such as components for the aerospace and engineering industries.

The laboratory researchers emphasize that these sensors and actuation devices would be not only stronger, but also cheaper than nickel-titanium. Thus, they can reduce the cost of production of household equipment, fire alarm sensors, connecting elements for aerospace and automotive components, and many other devices.

The scientists developed the material within the framework of the project called "Mechanisms of Phase and Structural Transformations in High-Strength Crystals of Iron and Nickel-Titanium Based Alloys with Conventional and Magnetic Shape Memory Effect." This project is supported by a grant from the Russian Science Foundation in the amount of $790,000. The goal of the program is to improve the quality of actuating mechanisms and sensors for mechanical engineering, aerospace, and other industries. The laboratory plans to continue studying these alloys.

The results of their study were presented at the international conference Alloys with Shape Memory Effect (St. Petersburg).

Liquidmetal amorphous alloy in hybrid knife is 25% harder than stainless steel

January 13, 2016
Source:

Liquidmetal Technologies Inc., Rancho Santa Margarita, Calif., has developed the Liquidmetal Hybrid Knife, manufactured of LM105 amorphous alloy by the Liquidmetal process. The 5.25-inch-long hybrid knife embodies a geometry that is not practical to produce with any other metalforming process. A 0.0005-inch fit between the blade and protector is made possible with the ultra-precise Liquidmetal process that can produce parts with features down to eight ten-thousands of an inch.

The barrel hinge implemented utilizing Python programming results in an easy-to-assemble and disassemble two-piece knife with no weak points throughout the open-and-close rotation. The alloy provides as-molded 563 Vickers hardness (25% greater than 17-4PH stainless steel), 1524 MPa yield strength (twice that of titanium), and 1.8% elasticity (four times that of hardened 420 stainless steel). Cultivated by an abundance of scientific data, the hybrid knife and Liquidmetal process stand in a league of their own. Not to be overlooked, the artistic and distinctive design brings a powerful process and set of material properties to life.

Liquidmetal also announces that it has shipped a pre-production order to CoNextions Medical for a key component to be used for suture-based tendon repairs. The initial parts delivery will be used to complete various tests, and will be followed by a full production shipment currently scheduled for early 2016.
