Ontario eyes new nuclear development
A 1,300-acre site left undeveloped on the shores of Lake Ontario four decades ago could see new life as the home to a large nuclear facility.

Laser powder bed fusion (LPBF), also known as selective laser melting, of Glenn Research Copper 84 (GRCop-84), a Cr2Nb (8 at. % Cr, 4 at. % Nb) precipitation-hardened alloy, produces a fully dense, high-conductivity alloy with tensile strength (470-MPa yield and 710-MPa ultimate tensile strength) superior to other competing copper alloys. Agglomeration and coarsening of precipitates in gas atomized GRCop-84 powder occurred above a threshold of 17 μm in diameter. Area of precipitates within cross sections is consistent among powder particles of different diameters indicating a consistent atomization process. Precipitates within gas atomized powder were shown to either melt and subsequently re-precipitate as the melt pool rapidly cools or break apart during LPBF resulting in precipitates smaller than in the initial powder. Precipitate size in powder therefore does not affect precipitate size, and thus tensile strength, in LPBF GRCop-84.
