Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

THE INFLUENCE OF SOME INPUT FACTORS IN THE LASER BEAM CUTTING PROCESS ON THE SURFACE ROUGHNESS

Nonconventional Technologies Review
Laser beam cutting of metallic workpieces is a frequently used process nowadays, due to the possibilities of cutting according to predetermined contours and the relatively small size of the slit width resulting from cutting.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Theory for acoustic propagation in materials which can support stress and which contain gas bubbles, with applications to acoustic effects in marine sediment and tissue

, 2007
Whilst there is a considerable body of work in the literature on the theory of acousticpropagation in marine sediment, the incorporation of gas bubbles into such theories isdone with the inclusion of assumptions which severely limit the applicability of ...
