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.

Numerical simulation of flow and heat transfer around vertical cylinder submerged in water
, 2015 Natural convection flows around submerged heated cylinders have gained attention in recent years due to their use in many engineering applications such as flow around tubes and rods (as in nuclear reactors and spent fuel cooling ponds).

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites
Advanced Engineering Materials, EarlyView.Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Policy Reform and Agricultural Adjustment in Transition Countries
After the fall of the Berlin Wall at the end of the 1980s, dramatic institutional and economic reforms took place in countries in Eastern Europe and the former Soviet Union. Agriculture was dramatically affected by these changes in policies.

Foreign direct investment and trade in transition countries: Tracing links [PDF]
Several studies have emphasized the links between trade reorientation and industrial restructuring in transition countries. In these studies trade has usually been considered as transactions among unrelated enterprises in different countries. However, an

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.
