Researchers at a Texas university recently announced a discovery involving the increased capability of high-temperature shape memory alloys (HTSMAs) that will improve fuel efficiency in jet engines and reduce airplane noise, as well as applications in several other industries.

Dr. Ibrahim Karaman, Chevron Professor I and head of Texas A&M University’s Department of Materials Science and Engineering

The team of researchers, led by Dr. Ibrahim Karaman, Chevron Professor I and head of Texas A&M University’s Department of Materials Science and Engineering, and including Demircan Canadinc, William Trehern, and Ji Ma of Texas A&M, and Fanping Sun and Zaffir Chaudhry, Technical Fellow of the United Technologies Research Center (UTRC), published their work in Scripta Materialia.

The accomplishment is critical because until now the use of HTSMAs has been limited to temperatures up to but not exceeding 400°C (752°F), but changing the elements that make up the HTSMAs allow for higher temperatures and therefore wider application.

“Karaman and his colleagues decided to try increasing the operating temperatures of HTSMAs by applying principles from another new class of materials, high-entropy alloys, which are composed of four or more elements mixed together in roughly equal amounts,” explained Texas A&M Today. “The team created materials composed of four or more elements known to form shape-memory alloys (nickel, titanium, hafnium, zirconium, and palladium), but purposefully omitted gold or platinum.”

When we mixed these elements in equal proportions we found that the resulting materials could work at temperatures well over 500 degrees C—one worked at 700 degrees C—without gold or platinum. That’s a discovery. It was also unexpected because the literature suggested otherwise. . . . What excites me is that we have just scratched the surface of something new that could not only open a completely new field of scientific research but also enable new technologies. ~ Dr. Ibrahim Karaman

Process Control Methods Standard Debuted for Aerospace Applications

 

A global association committed to providing and monitoring standards for the engineering profession recently published a new standard with guidance material to support specific aerospace engine applications, with a focus on the practical application of control methods for many different situations.

Dan Eigenbrode, vice president of module centers & supplier quality at Pratt & Whitney and AESQ Executive Sponsor for AS13006

SAE International in Warrendale, PA, released AS13006: Process Control Methods, which AESQ Strategy Group members will accept the immediate use of AS13006 within their respective supply chains. In addition, organizations are strongly encouraged to begin using this latest standard before it becomes a contractual requirement.

Aerospace engine manufacturers and their suppliers currently have differing requirements for process control that have similar intent. This new SAE standard establishes a common practice and methodology, defining the requirements for ongoing process control to improve quality performance through optimized process variation management beyond customer-defined key characteristics.

“The release of AS13006 is a big step forward in harmonizing requirements in the Aero-Engine supply chain,” said Dan Eigenbrode, vice president of module centers & supplier quality at Pratt & Whitney and AESQ Executive Sponsor for AS13006. Aerospace Engine Supplier Quality (AESQ), an SAE ITC program, was founded and formed by major aerospace engine companies to standardize quality requirements across the supply chain.

“Process Control is the key ingredient for sustained product quality and AS13006 provides the means for all suppliers to implement robust systems to ensure consistent quality regardless of product type,” added Eigenbrode.

AS13006, the previously released AS13003, Measurement Systems Analysis Requirements for the Aero Engine Supply Chain, and AS13004, Process Failure Mode and Effects Analysis (PFMEA) and Control Plans align and support the SAE standard AS9145, Requirements for Advance Product Quality Planning and Production Part Approval Process, developed by the International Aerospace Quality Group (IAQG)/SAE G-14 AAQSC Committee. The SAE G-22 AESQ Committee and the IAQG/SAE G-14 AAQSC Committee worked together cooperatively to ensure proper alignment of these standards.This standard also aligns and collaborates with the requirements of AS9103, Quality Management Systems – Variation Management of Key Characteristics.

Although designed for the aerospace engine supply chain, AS13003, AS13004, and AS13006 may be applied effectively by other segments of the aviation, space, and defense industries.

The Aerospace Engine Supplier Quality (AESQ) Strategy Group, a program of the SAE ITC, was established to develop, specify, maintain, promote, and deploy quality standards specific to the aerospace engine supply chain. AESQ member companies include Arconic, GE Aviation, GKN Aerospace, Honeywell Aerospace, MTU Aero Engines, PCC, Pratt & Whitney, Rolls-Royce, and Safran.
