摘要

Provided are a jet device and systems and methods using the jet device for manufacturing objects by additive manufacturing, especially titanium and titanium alloy objects, wherein the jet device directs a cooling gas across a liquid molten pool, or to impinge on the liquid molten pool, or to impinge upon a solidified material adjacent to a liquid-solid boundary of the liquid molten pool, or to impinge on an as-solidified material, or any combination thereof, during the additive manufacturing process. The application of the cooling gas can result in an additively manufactured metal product having refined grain structure with a high proportion of the grains being approximately equiaxed, and can yield an additively manufactured product exhibiting improvements in strength, fatigue resistance, and durability.
