A modified fibrous-like eutectic structure strongly improves the final mechanical properties of
Al–Si foundry alloys, especially ductility. Beside widely used commercial eutectic modifiers …

Abstract In Selective Laser Melting (SLM) layers of atomized powder are spread sequentially
on a building platform and melted locally by a laser beam. The melt pool is quenched by the …

Abstract Al–5 wt.% Si-based alloys with 0.05 wt.% Eu addition were produced by controlled
sand-casting and melt-spinning, respectively. The modification of eutectic Si caused by 0.05 …

While melt undercooling is often observed during solidification the control of undercooling
and nucleation is difficult due to the numerous possible heterogeneous sites present in even …

Abstract As-cast Al‒Si alloys always face low ductility because of coarse α-Al grains and
large lamellar eutectic Si. Although B-containing refiners and Sr modifiers could refine the α …

Abstract A new Al–Si–Mg alloy was prepared and refined by C-doped TiB 2 (C-TiB 2) and
strengthened by SiC, and the effects of microstructure configuration on the mechanical …

Micro-and nanostructure investigations of AlSi10Mg alloy powders and additive
manufactured samples were performed to highlight common effects related to very fast local …

The growth characteristics of eutectic Si in unmodified and Sr-modified Al–12.7% Si alloys
were investigated by microstructure-correlated crystallographic analyses. For the unmodified …

Al-Si cast alloys are usually composed of α-Al and Al-Si eutectic. Si flakes and Al matrix
generally hold cube-on-cube orientation relationship with the primary interface (111) A …

Alloying technology usually improves the mechanical properties of alloys; however, the high
cost of alloying elements limits their wider applicability to conventional cast aluminium …
