چکیده
Herein, the effects of Si content on microstructure evolution Al-Mg-Si alloys during twin-roll casting (TRC) and subsequent heat treatment were characterized using scanning electron microscopy, emission probe micro analysis, backscatter diffraction, transmission microscopy. The insoluble particles, solute gradient, recrystallization mechanical properties alloy in T4P state analyzed. An inhomogeneous deformation thickness direction TRC strip was observed pre-strain test. A premature local at element barren region (EBR) middle considered to be origin limited properties. By increasing from 0.7 wt% 1.1 wt%, uniformity EBR can effectively improved. stronger work-hardening ability weakens deformation. addition significantly increased number particles treatment. structure with a hard shell soft core reduced negative effect tensile strength uniform elongation 159.44 MPa 18.36% 209.96 29.791%, respectively.

Modification of Primary Si Crystals and Fe-rich Intermetallics in LM28 Al Alloy Fabricated Through Thixoforming
In the present research, thixoforming route was carried out in order to enhance the microstructural features of LM28 piston alloy. Typical microstructure of this alloy was composed of coarse, polygonal primary silicon particles, eutectic matrix and intermetallic phases. Thermal analysis was carried out to study the solidification path of the base alloy and determine the major arrest temperature...
متن کاملThe Effect of Cu Additions on the Precipitation Kinetics in an Al-Mg-Si Alloy with Excess Si
The microstructural evolution during age hardening of a Cu-bearing Al-Mg-Si alloy has been investigated by the three-dimensional atom probe (3DAP) and transmission electron microscope (TEM) techniques, in order to clarify the effect of Cu on the initial age-hardening response. After 30 minutes of artificial aging at 175 8C, the alloy shows a significant increase in hardness. The TEM observation...
متن کاملThe Effects of Gating Systems on the Soundness of Lost Foam Casting (LFC) Process of Al-Si Alloy (A.413.0)
The effects of gating systems, number of runner, and their locations, in the Lost Foam Casting (LFC) of Aluminum alloy (A.413.0) were investigated. Six different gating systems, with one or two running systems were designed. X-ray radiography and the three axis-bending tests have been employed to evaluate the casting soundness and quality. The results revealed that gating systems have a major e...
