High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...

Accelerated Fatigue Testing of High‐Speed Steel
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The staircase method is commonly employed in the characterization of metals to determine their fatigue limit. In this approach, the stress amplitude is systematically varied around the assumed fatigue limit in consecutive tests. However, its applicability for in‐process optimization in alloy design and development is limited by the large ...

Hot Isostatic Pressing of SY625 Powder
Superalloys 718, 625, 706 and Various Derivatives (1997), 1997 Hot Isostatic Pressing (HIP) is an established process for compacting powder materials far below their melting point. It allows to produce net-shape parts in order to reduce machining costs or to obtain non machinable geometries. In the HIP process, a steel container is tilled with the superalloy powder, out-gassed, and then submitted to simultaneous ...

Static recrystallization of shocked calcite in Ries impact breccias
Meteoritics &Planetary Science, EarlyView.Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia
