Titanium Aluminide Cyclic Oxidation Kinetics

, 2022
Strogi zahtevi automobilske i avio industrije, kao i kosmonautike, usmereni su na upotrebu lakih konstrukcionih delova visokootpornih prema otkazu i degradaciji na povišenim temperaturama. Titan aluminidi su zbog svoje male gustine i dobrih mehaničkih svojstava na povišenim temperaturama prepoznati kao materijali koji bi mogli ispuniti prethodno ...
