Additive manufacturing (AM) is emerging as an alternative to conventional subtractive
manufacturing methods with the goal to deliver unique and complex net or near-net shaped …

Ultrasonic fatigue tests were performed to investigate high and very high cycle fatigue
behaviors of a laser additively manufactured Inconel 718 (IN718) alloy in the as-deposited …

Abstract Ultrasonic Nanocrystalline Surface Modification (UNSM) offers an efficient and cost-
effective approach for enhancing material mechanical properties by inducing Severe Plastic …

The defect tolerance of three different martensitic stainless steels (17-4PH, X20Cr13 and
AISI403) under cyclic loading was investigated. Fatigue tests were performed with …

Push-pull and torsional fatigue tests were conducted using additively-manufactured, Ni-
based superalloy 718 samples with various defects and different microstructures, aiming to …

SN data of TC17 titanium alloy with surface defects exhibits plateau region (10 5-10 9
cycles) feature. The effects of defects are greatly related to the defect size. When the defect …

The use of fracture mechanics based methodologies to assess the influence of defects on
the high cycle fatigue resistance of mechanical components has become increasingly …

Ultrasonic fatigue testing is an increasingly used method to study the high cycle fatigue
(HCF) and very high cycle fatigue (VHCF) properties of materials. Specimens are cycled at …

Room-temperature high-cycle fatigue (HCF) of IN718 repaired joint via laser direct energy
deposition (DED) were studied with the fatigue axis perpendicular to the joint interface …

The influence of the micronotch size on the small fatigue-crack behavior of CP-Ti was
investigated in this study. With an increase in the equivalent micronotch size, the fatigue life …
