Nowhere is the need for material integrity more obvious than in medical devices that are implanted into human beings. A failed device inside an aircraft or power plant may, under some circumstances, cause a problem.
Ductile iron is an iron-carbon casting material whose matrix includes carbon in the form of nodular graphite particles. Rounded graphite nodules in the ductile iron matrix offer greater resistance to stress concentration when compared to graphite flakes (as in gray cast iron) and, therefore, inhibit the creation of cracks.
Since its venture into 3D-printing, Ghent University has expanded into supporting new materials and manufacturing research in a variety of industries, including fatigue testing of 3D printed titanium. Its latest efforts include projects on both polymers and metals.
It’s the year 2017. These days, it’s not uncommon for us to encounter several pieces of technology before we even leave the house in the morning. Simple devices like coffee makers and alarm clocks have had a space in our homes for decades, and with the entrance of the digital age, have made some impressive strides in technological advancement over the last several years.
Accepted by the FAA in 2009 for the repair and alteration of commercial aircraft structural and engine components, Lambda Technologies’ LPB provides a deep layer of compressive residual stress to mitigate fatigue, stress corrosion cracking (SCC) or foreign object damage (FOD) in the critical areas of metallic components without altering either the material or design.
