Grain refinement and mechanical property improvement in IN625 alloy deposited by in-situ hot rolling assisted laser directed energy deposition

A headache problem has recently been highlighted in the laser directed energy deposited (LDED) IN625 alloy, where columnar grains with a large size are prevalent due to the complex heat flow effect. Influenced by this, the LDED IN625 alloy generally shows a low strength and severe anisotropy of mech...
