Abstract In alloys where carbides are the main grain boundary phase, role of during hot working is not known. Here, we address effect on dynamic recrystallization compression Ni-base superalloy Haynes 282. When excluding variations from experimental factors neither stress evolution nor final microstructure indicated that exerted a significant influence recrystallization. The carbide solvus temp...

Recrystallization, which can occur dynamically or statically, is an importantphenomenon causing microstructure changes in deformed metals and therefore affecting theproperties of the material. Even though extensive investigations have been carried out on thenumerical modeling of recrystallization, the literature lacks accurate recrystallization modelswhich are able to predict mi...

Additive friction stir deposition (AFSD) is attractive for its ability to create freeform and fully dense structures without melting solidification. Hence, additive an alternative fusion-based manufacturing technology. In this study, the influence of AFSD parameter (i.e., rotational speed feed rate) on mechanical properties microstructure 6061 aluminum alloy investigated. The as-deposited exhib...

The hypoeutectic composite material composed of BCC phase and in situ precipitated Ti5Si3 was prepared by adding Si into MoNbTaTiV high-entropy alloy. obvious oriented formed eutectic with the inter-dendritic area, which leads to excellent properties composite. alloy exhibits ultra-high yield stress 718 MPa at 1200 °C compression plasticity. After reaching maximum strength, dynamic recovery (DR...

a review on the microstructural evolution in magnesium alloys during severe plastic deformation waspresented. the challenges deserved to achieve ultrafine/ nanostructured magnesium were discussed.the characteristics of the processed materials are influenced by three main factors, including i)difficult processing at low temperatures, ii) high temperature processing and the occurrence ofdynamic r...

It is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (DCR). However, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. In general, multi-directional defor...
