This paper provides a numerical assessment of the ductile fracture AA6101 and AISI 4340 alloys using Lemaitre Gurson models.The simulations were carried out to verify evolution accumulated plastic strain at fracture, assuming high range triaxiality ratio, applying monotonic tensile loads on smooth notched cylindrical specimens. The strategy was structured for models, from establishing non-linea...

This article compares the creep testing behavior of AISI 4340 high-strength steel in as-received and coated conditions. The coating material used was a NiCrBSi self-fluxing alloy. microstructural characterization carried out using optical scanning electron microscopy. tests were conducted at temperature 550 °C with loads 200, 250, 300 MPa. microstructure analysis deposited layer revealed some i...
