Microscopy:Article Title: Influence of Ultrasonic Surface Rolling Process on Surface Integrity and Internal Porosity in Selective Laser Melted CP-Ti Article Snippet: In this work, a comprehensive investigation was conducted on the effects of the ultrasonic surface rolling process (USRP) on selective laser melted (SLM) commercial pure titanium (CP-Ti), focusing on surface integrity and internal porosity.. USRP was found to generate nanocrystalline structures on the surface and form a hardened, plastically deformed, and densified layer, while introducing beneficial residual compressive stress.. USRP primarily enhances the surface integrity of SLM CP-Ti through surface wear. Article Title: High strain rate superplasticity in a cold rolled Fe35Mn8Al0.3C low-density steel Article Snippet: ..

Here, a heterogeneous lamellar structure (HLS) was introduced into Grade 4 CP-Ti by 85% cold rolling and short-time annealing at 550 C. The resulting microstructure, consisting of recrystallized soft grains embedded in a retained deformed hard matrix, achieved a superior strength-ductility combination compared with homogeneous coarse-grained and cold-rolled states of the same composition.. Quasi in situ electron backscatter diffraction (EBSD), transmission electron microscopy (TEM), loading-unloading-reloading (LUR) tests, and digital image correlation (DIC) were used to examine the deformation and hardening behavior.

Analysis:Article Title: Microstructure and wear performance in hBN containing carbide-based cermet Article Snippet: This study elucidates the strengthening and toughening mechanism of hexagonal boron nitride (hBN) containing WC-Co carbide-based cermet.. The microstructural evolution of the WC hard phase, phase transformation of the Co binder, grain boundary and interfacial characteristics are investigated.. The results demonstrate a slight decrease in WC grain size and the formation of a new W2Co21B6 phase after adding hBN. other:Article Title: Mechanistic investigation of laser shock peening on high cycle fatigue behavior and microstructural evolution in MAR-M247 nickel based superalloy Article Snippet: The study investigated the impact of laser shock peening (LSP) on the high cycle fatigue (HCF) performance of MAR-M247, while also discussing the strengthening mechanisms in conjunction with microstructural evolution and numerical simulations.. The LSP introduced a hardened layer with a depth of approximately 260 μm, and the surface hardness increased by 27.2% compared to the base material (BM).. Numerical simulation results indicated that LSP generated a Compressive residual stress (CRS) layer with a depth of about 250 μm in the surface region, with a maximum average CRS of 409 MPa. |
