Nanosteel, Providence, has delivered its first advanced high strength steel (AHSS) sheet to General Motors for initial evaluation of its role in vehicle lightweighting to meet rising global fuel-economy regulations. The steel is the result of a multi-year joint development program between NanoSteel and AK Steel Corp., West Chester, Ohio.
NanoSteel's commercially produced automotive sheet steel overcomes the historical tradeoff between strength and formability by delivering exceptional levels of both properties at the same time (approximately 1200 MPa tensile strength and 50% elongation). The high strength allows designers to create parts utilizing thinner-gauge material, while the high elongation allows manufacturers to produce the newly designed parts without expensive processing techniques, employee retraining, or additional capital costs. The unique combination of properties also allows engineers the design freedom to create novel part shapes, which further reduce weight.
"Many advanced materials with outstanding properties end up abandoned because they are too hard to use or too expensive to make," says NanoSteel CEO and president David Paratore. "NanoSteel's advanced high strength steel is designed to be both easy to produce—using conventional alloying elements with standard slab casting equipment; and easy to use—enabling the stamping and forming of parts at room temperature without additional manufacturing infrastructure or investment, such as that required for ‘hot' stamped parts."
AK Steel CEO Roger Newport commented, "We are pleased to partner with Nanosteel to bring this exciting new product to the market. As the first steel producer to manufacture this unique product using traditional slab casting, we are proud to add this accomplishment to our long and successful track record of innovation."
Mr. Paratore added, "We are confident that the exceptional properties of NanoSteel's sheet will enable automakers to affordably meet the ever-changing requirements of vehicle design and foster a new era of steel competitiveness in the battle of material choice."

Dual-beam laser spike anneal system enables process flexibility in chip production
April 24, 2016
Source:
Ultratech Inc., San Jose, Calif., announces a follow-on order from a major foundry for its LSA101 laser spike anneal system equipped with the dual-beam option, which provides a second low-power laser that adds flexibility to chip production. The dual beam enhances yield and enables low thermal budget processing that is required for advanced applications such as gate stack formation, silicide, or post-silicide anneal.
The system will be used for 28nm production, and is expected to ship in the second quarter of 2016.
The industry is experiencing a second wave of growth in the advanced planar node technologies, including 28nm logic. This is due to the high cost and challenges to manufacturing chips at leading-edge FinFET nodes; lithography alone represents close to 45% of the overall spending when considering triple patterning and other advanced lithography techniques. As a result, many foundries, especially those in China, are expanding their 28nm capacity as end customers take advantage of the optimal performance-to-cost ratio at this node. This trend may extend the 28nm node longer and at larger volumes than previously expected.
"This LSA system order is an example of the growing manufacturing opportunities for cost-effective nodes such as 28nm and above," says Arthur W. Zafiropoulo, Ultratech Chairman and Chief Executive Officer. "When comparing the different nodes, 28nm was the last strong planar node and provided the lowest cost per transistor. As a result, customers around the world are increasing their 28nm capacity." Built on the customizable Unity Platform, LSA101 with the dual beam option expands the process space by adding a second low-power laser beam that adds process flexibility and enables millisecond annealing with a low thermal budget process.
Inserting a millisecond anneal step post-junction formation, such as gate stack formation, silicide, or post-silicide anneal, has been shown to improve leakage and device reliability, while reducing contact resistance and improving both performance and yield.
Compared to competing millisecond annealing technologies, LSA with dual beam offers the lowest thermal budget millisecond anneal process, along with superior within-die uniformity for different layouts. This performance is provided at a significantly lower cost of ownership, due to higher throughput and low cost of consumables. The LSA101 delivers high flexibility and extendibility for advanced annealing applications, and is currently in high-volume production for 28nm and below logic devices.

One Minute Mentor: Carburizing Tool Steels
April 22, 2016
Source:
P20 mold steel is seldom carburized for molds used in compression molding, particularly for molding the more abrasive plastics. Carburizing temperatures no higher than 1650°F are recommended for this steel because higher temperatures may impair polishability; otherwise, conventional carburizing practice is used, and molds may be quenched in oil directly from the carburizing temperature. A common working range is 54 to 58 HRC.
The graph shows tempering characteristics of carburized mold steels.
(a) Upper curve represents steel carburized in hardwood charcoal 1675 to 1700°F for 8 hours, air cooled in pack, reheated at 1725 to 1750°F, cooled in air, and tempered. Middle curve represents steel carburized in cast iron chips at 1725 to 1750°F, removed from pack, cooled in air, and tempered.
(b) Surface hardness after heating at temperature for 2 hours in carburizing compound, followed by oil quenching and tempering.

ATI announces restructuring of Flat Rolled Products operations
Source:
Allegheny Technologies Inc., Pittsburgh, announces the next phase in the restructuring of its Flat Rolled Products (FRP) operations with the reduction of approximately one third of FRP's salaried workforce through the elimination of over 250 positions. This workforce reduction will be completed by the end of the second quarter 2016. As a result of these actions, ATI will record a $9 million severance charge in first quarter 2016 results. These actions are expected to generate annualized cost savings benefits of over $30 million beginning in the third quarter 2016.
"Reducing our flat-rolled products business' dependence on unprofitable commodity products is a difficult process," said Rich Harshman, Chairman, President and CEO. "We believe in U.S. manufacturing. However, it is difficult for a U.S.-based company to compete in the global commodity markets, particularly when significant global overcapacity exists for products such as commodity stainless steel sheet and grain-oriented electrical steel (GOES). The restructuring and right-sizing actions we are taking, while painful for our employees and our company, are necessary to help secure the future of ATI Flat Rolled Products.
"We are in the process of creating a smaller, more agile, streamlined, cohesive, and efficient FRP business that will focus on products and markets with significant technical barriers to entry. As previously announced, our stainless steel facility in Midland, Pa., has been idled to reduce our exposure to commodity stainless steel sheet. Our GOES operation will be idled this month. These actions improve ATI's focus on differentiated flat-rolled products that serve growing global markets. The future restart of the idled operations depends on future business conditions and ATI's ability to earn an acceptable return on invested capital on products manufactured at these operations.
"The reduction in FRP's salaried workforce is another step in our journey to return the FRP business to profitability as quickly as possible, and to execute our strategy for sustainable long-term profitable growth. We expect the FRP business to be modestly profitable in the second half of 2016."
