Abstract (en)
Methods of forming a compressor article such as a cast airfoil, a stator, a blade, a gas turbine, and a gas turbine shell via casting are presented. The methods include: preparing an iron-manganese-aluminum-silicon-carbon (Fe-Mn-Al-Si-C) based alloy; casting the Fe-Mn-Al-Si-C based alloy, wherein a cast has a shape of the compressor article; and performing post-casting finishing thereby forming the compressor article.
