Microstructural Evolution in Large-Section Plastic Mould Steel during Multi-Directional Forging

چکیده
To obtain excellent mechanical properties from large cross-sections of plastic mould steel (SDP1), we conducted multi-directional forging (MDF) to control the microstructure ingots. investigate microstructural evolution SDP1 during MDF, performed hot at 1150 °C using a THP01–500A hydraulic press. The dimensions specimens were Φ38 mm × 80 mm. after was observed under metallographic microscope. Furthermore, results finite element method (FEM) simulations employed improve quality forgings. predicted agreed well with experimental ones, indicating that FEM is effective for analysing MDF. Thus, MDF (Φ1000 2200 mm) simulated. showed average grain size core an ingot ranged 40.6 43.3 μm. Although this slightly higher than sample traditional upsetting and stretching (TUSF) (35.7–46.0 μm), more uniform TUSF. Compared TUSF, not only refines but also improves uniformity sample.

Texture Evolution in Low Carbon Steel Fabricated by Multi-directional Forging of the Martensite Starting Structuree
It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel. This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...

The hot compression tests were carried on X45CrNiW189 valve steel (X45) in the temperature range of 1000– 1200 °C and the strain rate range of 0.004 – 0.5 s-1 in order to study the high temperature softening behavior of this steel. For the exact prediction of flow stress, the effective stress-effective strain curves were obtained from experiments under various conditions. On the basis of experi...

متن کاملMicrostructural evolution during film growth
Atomic-scale control and manipulation of the microstructure of polycrystalline thin films during kinetically limited low-temperature deposition, crucial for a broad range of industrial applications, has been a leading goal of materials science during the past decades. Here, we review the present understanding of film growth processes—nucleation, coalescence, competitive grain growth, and recrys...
