The Effect of Heat Accumulation on the Local Grain Structure in Laser-Directed Energy Deposition of Aluminium

The Effect of Heat Accumulation on the Local Grain Structure in Laser-Directed Energy Deposition of Aluminium

The energy used to melt the material at each layer during laser-directed energy deposition (L-DED) accumulates in the solidified layers upon layer deposition and leads to an increase in the temperature of the part with an increasing number of layers. This heat accumulation can lead to inhomogeneous...
