Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]

MATEC Web of Conferences, 2018
Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Effect of ultrasonic nanocrystal surface modification on the characteristics of AISI 310 stainless steel up to very high cycle fatigue [PDF]

, 2016
Effects of ultrasonic nanocrystal surface modification (UNSM) on the very high cycle fatigue response of AISI 310 stainless steel have been investigated. The higher impact force used in UNSM treatment showed a higher fatigue life improvement. The fatigue

On specimen design for size effect evaluation in ultrasonic gigacycle fatigue testing [PDF]

, 2014
Literature datasets showed that gigacycle fatigue properties of materials may be affected by the specimen risk-volume, i.e., the part of the specimen subjected to applied stress amplitudes above a prescribed percentage of the maximum applied stress ...

Very high cycle fatigue (VHCF) response of an Additively manufactured Nitinol

International Journal of Fatigue
This work investigates the Very High Cycle Fatigue (VHCF) response of an Additively Manufactured (AM) Nitinol alloy. To resemble in-service loading conditions of typical Nitinol components, an innovative experimental setup has been proposed, where the martensite/austenite transformation fraction is controlled by applying a mean static compressive load ...

VHCF Response up to 10⁹ Cycles of SLM AlSi10Mg Specimens Built in a Vertical Direction

Applied Sciences, 2019
It is well-known that many manufacturing parameters affect the quasi-static and the fatigue response of additive manufacturing (AM) parts. In particular, due to the layer-by-layer production, the load orientation, with respect to the building direction ...

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...
