Fluctuation of the Solute Concentration in Al Rich Al-Zn Alloys [PDF]

, 1978
Several Al-Zn alloys containing 0.041-4.4 at % Zn were studied by means of measurements of electrical resistivity. The results obtained are as follows : (1) The electrical resistivity increases when the specimen is annealed at temperatures higher than ...

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

Journal 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]

Tehnika, 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

Nuclear 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

Robust isothermal electric switching of interface magnetization: A route to voltage-controlled spintronics [PDF]

, 2010
Roughness-insensitive and electrically controllable magnetization at the (0001) surface of antiferromagnetic chromia is observed using magnetometry and spin-resolved photoemission measurements and explained by the interplay of surface termination and ...
