| Abstract Scope |
Metal Additive Manufacturing is being rapidly adopted by various industries to manufacture customized products and parts having complex designs. However, high thermal gradients between the parts and substrate often results in residual stresses in the final deposit, adding hindrance to the adoption of metal AM for critical applications. Parameter optimization often helps in residual stress mitigation. The current research aims to study the effect of inter-layer dwell time on residual stresses in directed energy deposition. Three levels of Inter-layer dwell time at high and low levels of volume energy density were deposited. Residual stresses of each sample were analyzed to identify the influence of variation of inter layer dwell time |
