The near-eutectic Al-12 wt.% Ce alloy has been alloyed with 0.4 wt.% Sc to improve its creep resistance. A bidirectional influence between Sc and Ce has been identified: (i) the Ce element suppresses the Sc partition between the liquid and solid phases during solidification, as implied by...
Metal matrix composite coatings consisting of an Al–12wt.% Si-alloy matrix reinforced with TiC were prepared by laser cladding from mixtures of Al–12wt.% Si alloy and TiC powders. For the processing parameters used (power density 200MW/m2 and interaction time 0.3s), a small proportion of...
Pressure infiltration of Al–12 wt.% Si–X (X = Cu, Ti, Mg) alloys into graphite particle preforms The pressure infiltration of Al and Al–12wt.% Si–X alloys into preforms of packed graphite particles has been investigated. Compacts were prepared from p... A Rodríguez-Guerrero,SA ...
2.2. Alloys The chemical compositions of the commercial aluminum (99.98 wt.%), the eutectic Al–12 wt.% Si alloy, and the Al– 12 wt.% Si–X alloys (X = Ti, Cu, Mg) used in this work are reported in Table 2. The alloys were melted in alumina cru-相关...
The high velocity oxy-liquid fuel (HVOLF) thermal spray technique has the potential to fabricate thick layers based on the Al–12 wt.% Sn–1 wt.% Cu alloy. The microstructure of the as-sprayed coatings exhibits several levels of complexity due to the effects of rapid quenching and metastabl...
