Effect of increased length fraction of Sigma 3(n) special boundaries on OAIC response of cold rolled Ni-based alloy 718 thin sheets

Effect of increased length fraction of Sigma 3(n) special boundaries on OAIC response of cold rolled Ni-based alloy 718 thin sheets

Among the well-established Ni-based superalloys, alloy 718 is one of the most widely used in the industry. However, its application is limited up to 650 degrees C due to the occurrence of the oxidation assisted intergranular cracking (OAIC) phenomenon. As a general rule, an increased fraction of spe...
