Researchers have reported a laser powder bed fusion aluminum alloy that reaches 582 MPa tensile strength at room temperature and retains 114 MPa strength with exceptional creep resistance at 400 C, thanks to embedded heat-resistant nanophases formed during printing.
6K Additive has won a $1.95 million Phase II contract from the Defense Logistics Agency to convert nickel, titanium, tungsten and niobium scrap from military depots into high-value powder for additive manufacturing.
A Nature Communications study published April 15 reports an additively manufactured aluminum alloy that pairs strength, ductility and heat resistance — a combination long sought for lightweight parts that must survive elevated temperatures.
