High Performance Alloys Database (HPAD)[Permalink]

The HPAD was created by CINDAS LLC to address the needs of the oil/gas, chemical processing, power generation and transportation industries. We were asked by many engineers in industries other than aerospace to produce a materials properties database analogous to the ASMD, in format, but more focused on the specific needs of these high performance industries including detailed data on corrosion testing and joining. About three years ago, we conducted an exhaustive study with materials experts in these industries as well as with the major manufacturers of high performance alloys. We developed an initial list of about 125 alloys of high interest to these industries. The inaugural release of the HPAD is scheduled for the first quarter of 2015. It will contain about 90 chapters with approximately 10-15 chapters being added during 2015. The HPAD has the same interactive features as the ASMD, TPMD and MPMD. Like our other three databases, it is web based and updated and expanded continually with carefully selected alloys.

Please view the HPAD Alloy Sheet that lists all the alloys included in the database. Note there is a major emphasis on nickel and cobalt, stainless steels and high strength steels as well as titanium. View the HPAD Alloy Sheet. Learn more about the HPAD and to try the Demo.

Looking for Important Armor Alloys Data Resources?[Permalink]

by Stan Setlak

Many aluminum alloys as well as some magnesium alloys are used for armor plating. Among prime examples of armament alloys are aluminum alloys 5083, 5456, 7039, 2519, 5059, 6061, 2139, 2195 and 7085. Because some of the alloys also play important roles in aerospace, they are found in the Aerospace Structural Metals Database (ASMD). Specifically, the alloys and applications are Al 5083 (vehicles), Al 5456 (naval), Al 6061, Al 7085 and Mg LA91A. Ballistic properties are addressed in their own section of many chapters along with the normal coverage of properties related to aerospace applications.

Thick Section Aluminum Aerospace Alloy - 7085[Permalink]

by Rob Pahl
In the fourth quarter of 2014 CINDAS LLC published a chapter on 7085 aluminum for the ASMD. The chapter was written by Dhruba Chakrabarti. He was the developer at the Alcoa Technical Center when it was developed and commercialized. Applications for Aluminum 7085 include structure in commercial and military aerospace for thick sections used in spars (Airbus A380 and Joint Strike Fighter) as well as for armor plate in military vehicles. Aluminum 7085 is produced in plate, die forgings and hand forgings.

The chapter is rich in property data with over 150 tables and figures which makes it the most detailed technical paper ever published on 7085. Data which is available in the chapter includes:
  • Fracture Toughness
  • Fatigue Crack Growth
  • Static Allowable Mechanical Property Data

Meet Our Authors[Permalink]

A new feature in the CINDAS LLC Newsletter is highlighting an active author who is writing chapters for the ASMD and/or the HPAD. We currently have over fifteen authors who are writing for CINDAS LLC.

We are pleased to introduce Dhruba Chakrabarti who has just completed a chapter on 7085 aluminum for the ASMD. He received his BS in Metallurgical Engineering at the University of Calcutta, India, and then his MS and PhD in Metallurgical Engineering from the University of Illinois. After graduation, he worked in research with experience for 14 years at the Steel Authority of India, National Metallurgical Lab in India and Carnegie Mellon University in Pittsburgh. Dhruba joined Alcoa in 1984 at the Alcoa Technical Center in Pennsylvania. While at Alcoa he earned the two highest technical awards - Chairman's Award for 7085 and the Arthur Vining Davis Award for the 7055-T77 team. He has seventeen issued patents and retired from Alcoa as a Technical Fellow. His work on concept-to-flight for development of 7085 plate and forgings is recognized globally in the aerospace industry.
