“…In addition to the arm spacings during directional solidification, gravity-driven convection can also influence the side-branch characteristics of freely grown equiaxed dendrites, and significant differences to corresponding microgravity experiments have been observed [277][278][279]. Forced convection, as in DC casting of aluminum alloys, can affect the formation of feathery grains made of twinned dendrites [280].…”

“…[14][15][16][17][18][19] It is noticed that substrate materials include steel, Al-Mg alloy, Mg alloy, etc., whereas reinforcements are mainly ceramic particles, such as Al 2 O 3 , TiC, and TiO 2 , etc. However, the application of powder metallurgy materials as substrates, in particular, the use of nanomaterials or nanoparticles as reinforcements of laser cladding layer, has never been reported in the literature.…”

“…Concluyen, que una superficie recubierta con este tipo de recubrimiento tiene una resistencia al desgaste entre 5 y 10 veces superior que la del substrato AlSi. Mc Cay et al [66] realizan aleaciones láser mediante la adición de partículas de silicio a un aluminio AA319 (5,5-6,5 % Si, 1% Fe, 3,0-4,0 % Cu, 0,5 % Mn, 0,1 % Mg, 0,35 % Ni, 3,0 % Zn + Al) [23] y comparan la resistencia al desgaste de distintos porcentajes de aportación. En general, observan una mejora en la resistencia al desgaste al aumentar la proporción de silicio.…”
