Effects of in-situ synthesized TiB2 on crystallographic orientation, grain size and nanohardness of AA6061 alloy by laser surface alloying
TL;DR: In this article, the effect of reinforced aluminum metal matrix composites (MMCs) were in-situ synthesized by laser surface alloying (LSA), and the results indicated that TiB2 particles mainly exhibited hexagonal plate-like morphology and distributed at high angle grain boundaries (HAGBs).

Correlation between microstructural heterogeneity and anisotropy of mechanical properties of laser powder bed fused CoCrFeMnNi high entropy alloy
TL;DR: In this article , the relationship between the hierarchical microstructure and mechanical properties along the horizontal, diagonal, and vertical directions of the LPBF-built CoCrFeMnNi high entropy alloy was qualitatively and quantitatively investigated.
Investigation on Microstructural Evolutions and Mechanical Properties of P92 Steel During Thermal Processing
TL;DR: In this paper, the grain growth behavior of austenite and δ-ferrite changes in P92 steel is comprehensively investigated through thermodynamic calculations and physical simulation, and the results show that the AC1, AC3 and γ-δ transformation temperatures of P92steel are 841, 878, and 1095, respectively, which are comparable to the measured values of 850,°C, 879, and 1175, respectively.
The elimination of pores in laser welds of AISI 304 plate using different shielding gases
TL;DR: In this paper, a laser power of 10kW was used to weld 304 stainless steel and the porosity in the laser welds was examined by a high-speed video camera.
