Role of grain size in governing the mechanical response in friction-stir-welded high-aluminum low-density ferrite steel
The susceptibility of high-Al ferritic steels to thermal cracking and microstructural coarsening during fusion welding restricts their practical implementation. To address this challenge, high-quality joints of Fe–10Al alloy were successfully fabricated by friction stir welding (FSW) under ultra-low rotation (80 r/min)...
