Interest:
Aluminium-Lithium alloys are age hardening alloys:
• Loss of properties with fusion welding methods
• Friction methods used to maintain the microstructure
Technical Objective:
• Increasing the joint efficiency using LFW
• Reduce “buy to fly” ratio via near net shaped blanks
• Materials tailoring:-
“Right material properties at the right location”
• Evaluate new “Design freedoms”
Focus on ™ alloy: 2050
• Constellium actively investigating LFW since 2009
• Collaborating with LFW OEM’s, institutes and end users
