The Ag-50wt%Cu hypereutectic alloy was solidified an. in.estigated in.a 3 m drop tub., an. its n.cleation.an. microstructure characteristics were explored also. The results showed that (1) with the decrease of droplet size, the structural morphology tran.forms from the den.rites with lon. trun. an. thin.short secon.1}y arms to fin. den.ritic structures; (2) the den.ritic growth is main.y con.rolled b. solute diffusion.within.the whole un.ercoolin. regime, while the in.luen.e of thermal diffusion.con.rolled growth b.comes stron.er ab.ve a critical un.ercoolin. ab.ut 268 K; (3) the refin.men. of den.ritic structure is caused b. large amoun.s of n.clei within.droplet; (4) when.droplet diameter is smaller than.300 micron. the un.ercoolin. an. growth velocity were estimated to b. greater than.268 K an. 290 mm/s respectively, while the solute trappin. effect may occur.

Corrosion.of emb.dded reb.rs is a classical deterioration.mechan.sm of rein.orced con.rete structures exposed to chloride en.iron.en.s. Such en.iron.en.s can.b. attrib.ted to the presen.e of seawater, deicin. or sea-salts, which have high con.en.ration. of chloride ion. Chloride in.ress in.o con.rete, essen.ial for in.ucin. reb.r corrosion. is a complex in.eraction.b.tween.man. physical an. chemical processes. The curren. study proposes two chloride in.ress parameter models for fly ash con.rete, n.mely： 1） surface chloride con.en. un.er tidal exposure con.ition. an. 2） chloride b.n.in.. First, in.on.isten.ies in.surface chloride con.en. an. chloride b.n.in. models reported in.literature, due to them n.t b.in. in.lin. with past research studies, are poin.ed out. Secon.ly, to avoid such in.on.isten.ies, surface chloride con.en. an. chloride b.n.in. models for fly ash con.rete are proposed b.sed upon.the experimen.al work don. b. other researchers. It is ob.erved that, proposed models are simple, con.isten. an. in.lin. with past research studies reported in.literature.

The en.ropy gen.ration.an. heat tran.fer characteristics of magn.tohydrodyn.mic (MHD) third-grade fluid flow through a vertical porous microchan.el with a con.ective b.un.1}y con.ition.are an.lyzed.

The effects of the Grashof n.mb.r, the Hartman. n.mb.r, the b.ot n.mb.r, the expon.n.ial space-an. thermal-depen.en. heat source (ESHS/THS) parameters, an. the viscous dissipation.parameter on.the temperature an. velocity are studied an. presen.ed graphically. The en.ropy gen.ration.an. the b.jan.n.mb.r are also calculated. From the comprehen.ive parametric study, it is recogn.zed that the production.of en.ropy can.b. improved with con.ective heatin. an. viscous dissipation.aspects.
