1. 16. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Belén Alonso Rancurel; [2023]
   Keywords : austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

   Abstract : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.
