Web11 apr. 2024 · In other papers [30,39,40,41], LPBF was also used to fabricate duplex stainless steel, and an as-built microstructure with nearly 100% ferrite content was also obtained. This is mainly due to the cooling rate of the metal being as high as 10 4 –10 6 K·s −1 during the LPBF process, which inhibited the transition from high temperature ferrite …
Web1 aug. 2024 · In this process, steel is heat-treated to obtain a tempered martensitic structure. It is then exposed to an atmosphere of ammonia at around 550ºC for 12-36 hours. Small alloying elements like Al or Cr enhance the formation of a fine dispersion of nitrides, which remarkably increase the surface hardness and wear resistance.
WebThe mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails.
