The mechanical properties and microstructure of many aluminium alloys have not been fully explored, as their manufacturability using SLM is extremely challenging. This study investigates the effect of laser power, hatch spacing and scanning speed on the mechanical and microstructural properties of as-fabricated aluminium 2024 alloy (AA2024 Effects of On-Line Vortex Cooling on the Microstructure metals Article E ects of On-Line Vortex Cooling on the Microstructure and Mechanical Properties of Wire Arc Additively Manufactured Al-Mg Alloy Baoxing Wang 1, Guang Yang 1,*, Siyu Zhou 1,*, Can Cui 2 and Lanyun Qin 1 1 Key Laboratory of Fundamental Science for National Defense of Aeronautical Digital Manufacturing Process, Shenyang Aerospace University, Shenyang 110136, China; Evolution of microstructure and mechanical properties of Evolution of microstructure and mechanical properties of Cu/SAC305/Cu solder joints under the influence of low ultrasonic power Semantic Scholar. Abstract Cu/SAC305/Cu solder joints were fabricated by a modified ultrasonic-assisted reflow soldering technique under ambient atmosphere. Ultrasonic vibration (USV) with low ultrasonic power ranging from 10 to 30 W was used while the evolution of
this differentiation is that there are clear differences between the mechanical properties of upper and lower bainite. Any refinement of microstructure in low alloy steels normally leads to an increase in the properties, particularly the strength, hence making lower bainite the more attractive microstructure. MICROSTRUCTURE AND MECHANICAL PROPERTIES this differentiation is that there are clear differences between the mechanical properties of upper and lower bainite.

Microstructure Evolution and Mechanical Properties of AZ31 magnesium alloy sheets were prepared by low-speed extrusion at different temperatures, i.e., 350 °C, 400 °C, and 450 °C. The microstructure evolution and mechanical properties of extruded AZ31 magnesium alloy sheets were studied. Results indicate that the low-speed extrusion obviously improved the microstructure of magnesium alloys.
The reasons for the excellent mechanical properties of P/M TaNbVTiAl0.2 RHEA were the uniform microstructure and solid solution strengthening effect. A series of TaNbVTiAlx (x = 0, 0.2, 0.4, 0.6, 0.8, and 1.0) refractory high-entropy alloys (RHEAs) with high specific strength and reasonable plasticity were prepared using powder metallurgy (P/M Microstructure and mechanical properties of Hastelloy Afterwards, the microstructure evolution and its relation with the modified mechanical properties is evaluated. 2 Material and experiments In the present work, a SLM280hl machine from SLM Solutions (Germany) was used to build the parts.
