Microstructure evolution and mechanical properties of multiple-layer laser cladding coating of 308L stainless steel

•Grain morphology transformations of 308L stainless steel multiple-layer are studied.•The cladding metals solidify in AF mode and consist of austenite and about 10.48% δ ferrite.•The ferrite content distributes into an increasing trend as the number of layers increase.•The distribution of hardness f...
