Precipitation strengthening of Cu–Ni–Si-based alloys: Experimental and computational insights
Journal of Materials Research and Technology, 2023 The effects of interfacial energy on precipitation behavior and physical properties of Cu–Ni–Si–(Co) alloys were investigated. The Cu–1.3Ni–0.3Si and Cu–1.3Ni–0.6Si–1.0Co alloys (in weight %) were prepared by combined cold-rolling and aging processes ...

Bauschinger effect in precipitation-strengthened aluminium alloy 2024
Materials Science and Engineering, 1987 Abstract The influence of precipitation strengthening on the Bauschinger effect of aluminium alloy 2024 has been investigated. The material was aged at 463 and 478 K for various lengths of time. Under certain aging and straining conditions, reverse flow curves with concave parts were observed.

Bulk microstructure evolution of two high Hf–containing nickel–based alloys during exposure at temperatures from 1100 to 1250°C [PDF]
Chemical Review and Letters, 2021 Two Hf–poorest versions of a high performance chromia–forming nickel–based polycrystalline cast alloy reinforced by HfC carbides were investigated by replacing more or less hafnium by tantalum to reduce production cost.

Microstructural characteristics of a Ni2TiAl-precipitate-strengthened ferritic alloy [PDF]
Journal of Alloys and Compounds, 2017 Abstract The microstructure of a Ni 2 TiAl-strengthened ferritic alloy at room and elevated temperatures is characterized, using scanning/transmission-electron microscopy (SEM/TEM) and neutron-diffraction (ND). The SEM/TEM results revealed that this alloy contains a L2 1 -type Ni 2 TiAl precipitate distributed in the Fe matrix, and the L2 1 ...

Precipitation Strengthening in Al-Mg-Si Alloys
, 2021 Precipitation strengthening is one of the key strengthening strategies in many industrial alloys like aluminum alloys, nickel-based superalloys, etc. The yield strength of alloy is improved by forming precipitates in materials and employing them as obstacles for dislocation movement.
