摘要: Abstract Besides turning to less energy-intensive power train options, lightweighting is commonly regarded as the most effective way reduce a vehicle's environmental impact. Achieving high recycling rates for lightweight materials important goal, lest advantages afforded by vehicle are unduly diminished or even annulled. Additionally, in order reap full benefits of terms avoided primary (virgin) material production, it desirable that quality recycled scraps be kept close possible demanded original application. Solution Heat treatment, Forming and in-die Quenching (HFQ) novel sheet metal forming process allows large parts without need extraneous rivets other bonding techniques which impair end-of-life disassembly recycling. Our comparative life cycle assessment has shown additional energy required HFQ over-compensated ensuing enhanced recyclability, thereby potentially resulting an overall net improvement profile manufactured over their cycle.
