Dynamic recrystallization mechanisms and twining evolution during hot deformation of Inconel 718 [PDF]

, 2016
The hot deformation behavior of an IN718 superalloy was studied by isothermal compression tests under the deformation temperature range of 950–1100 °C and strain rate range of 0.001–1 s-1 up to true strains of 0.05, 0.2, 0.4 and 0.7.

Collaborative simulation method with spatiotemporal synchronization process control [PDF]

, 2016
When designing a complex mechatronics system, such as high speed trains, it is relatively difficult to effectively simulate the entire system’s dynamic behaviors because it involves multi-disciplinary subsystems.

Investigation of dry sliding wear properties of multi-directional forged Mg–Zn alloys

Journal of Magnesium and Alloys, 2019
Effect of multi-directional forging (MDF) on wear properties of Mg–Zn alloys (with 2, 4, and 6 wt% Zn) is investigated. Dry sliding wear test was performed using pin on disk machine on MDF processed and homogenized samples.

Progress in mixed Eulerian-Lagrangian finite element simulation of forming processes [PDF]

, 1990
A review is given of a mixed Eulerian-Lagrangian finite element method for simulation of forming processes. This method permits incremental adaptation of nodal point locations independently from the actual material displacements.

Refinement mechanism of centimeter-grade coarse grains in as-cast Ti2AlNb-based alloy during multi-directional forging

Materials & Design, 2023
Centimeter-grade coarse grains commonly exist in heavy ingots of Ti2AlNb-based alloy and severely deteriorate their workability. To investigate the refinement of coarse grains, multi-directional isothermal forging (MDIF) was carried out on samples cut ...
