2. 1. Thermomechanical Processing of Nickel-Base Alloy 825

   Author : Munir Al-Saadi; Pär Jönsson; Christopher Hulme-Smith; Göran Engberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 825; Cast and wrought structures; Hot compression test; Microstructural evaluation; Modelling; Yield strength; Strengthening mechanisms; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : Alloy 825 material was studied using a Gleeble-3800 thermosimulatorby performing single-hot compression experiments.Optical microscopy and electron backscatter diffraction wereutilized to characterize the microstructure. Dynamicrecrystallization is not considerable in the as-cast alloy anddislocation recovery is deemed to be dominant. READ MORE

4. 2. Development of high performance aluminium alloys tailored for powder bed fusion-laser beam

   Author : Bharat Mehta; Chalmers tekniska högskola; []
