Noting that AM Scalmalloy®, which has a yield of approximately 450 MPa and an elongation of greater than 10%, appears to have the potential to meet the stringent strength and ductility requirements for aircraft quality parts, and that the ability to characterise crack growth is central to airworthiness certification this paper addresses crack growth in the AM aluminium alloy Scalmalloy. It is shown that the curves for AM Scalmalloy essentially collapse onto a master curves that is similar to that associated with the growth of both long and short cracks in the aluminium alloy’s AA7075-T7351 and AA7075-T6. © 2020 The Authors.
