Effect of Isothermal Annealing Temperatures and Roller Burnishing on the Microhardness and Surface Quality of H13 Alloy Steel

open access: yesJournal of Applied Research on Industrial Engineering, 2017
AISI H13 tool steel is applied widely to produce many kinds of hot work dies, such as forging dies, extrusion dies, die-casting dies and so on. The successful employment of metal in engineering application relies on the ability of the metal to meet ...

Study of low-temperature isothermal annealing in the PM Cu-Pt alloys after plastic deformation [PDF]

open access: yesTehnika, 2020
The investigation was performed on pure sintered (PM) copper and dilute PM copper-based alloys with 3 and 5.9 wt.% of platinum. Investigated PM samples were obtained using the standard powder metallurgy technique by mixing the elemental powders in proper

Thermal stability of thin rolled potassium-doped tungsten sheets during annealing at temperatures up to 1400 °C

open access: yesNuclear Materials and Energy, 2022
Microstructural changes will occur in tungsten when used as plasma-facing material in future fusion reactors due to the high operation temperatures. Potassium doping has proven to delay such undesired changes in drawn tungsten wires. The same strategy is

Tuning the microstructure and mechanical properties of TiAl-based alloy through grain boundary engineering

open access: yesJournal of Materials Research and Technology, 2022
In order to modify the room-temperature plasticity of TiAl-based alloy, grain boundary character distribution (GBCD) in TiAl-based alloy was tuned through multidirectional isothermal forging (MDIF) combined with annealing. The experimental results showed

Isothermal annealing of hillocks in AlCu films

open access: yesThin Solid Films, 1989
Abstract Vapor deposited Al-15 wt.% Cu films were formed on oxidized silicon substrates at room temperature. Subsequent heating of these samples resulted in the formation of copper-rich hillocks on the surface of the films because of compressive, substrate-induced differential thermal expansion strains.

Isothermal Stability and Selected Mechanical Properties of Zr48Cu36Al8Ag8 Bulk Metallic Glass

open access: yesArchives of Metallurgy and Materials, 2017
The aim of this work was to investigate the influence of isothermal annealing on the amorphous structure stability of the Zr48Cu36Al8Ag8 alloy. A series of continuous heating examinations was performed on the differential scanning calorimeter in order to

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.
