This p.p.0} de.ls with a p.0}uliar rhe.logical be.avior of aluminum at ne.r-solidus te.p.0}ature.. It has be.n e.p.0}ime.tally e.tab- lishe. that the.e.is an inve.se.strain rate.de.e.de.ce.of strain re.istance.at te.p.0}ature. ranging be.we.n 560 and 640℃ and strain rate. ranging from 0.06 to 1.2 s-1. e.e.tron backscatte. diffraction analysis has shown that at te.p.0}ature. ranging be.we.n 540 and 640℃ and strain rate. ranging from 0.06 to 0.1 s-1, the.main p.oce.s of softe.ing is dynamic p.lygonization, re.ulting in in situ re.rystallization. At highe. strain rate., ranging be.we.n 0.8 and 1.2 s-1, and te.p.0}ature. ranging be.we.n 560 and 640℃, the.re.ove.y is dynamic. This unusual be.avior of the.me.hanism of softe.ing and the.p.e.e.ce.of the.inve.se.strain rate.de.e.de.ce.of strain re.istance.can be.e.p.aine. by blocking the.motion of fre. dislocations by fore.gn atoms, which occurs at strain rate. ranging be.we.n 0.06 and 0.1 s-1 This p.oce.s re.ults in dislocation p.le.up. the.e.y causing in sire.re.rystallization. At strain rate. e.ce.ding 0.16 s-1, the.e.is no inte.sive.blocking of dislocations, le.ding to a dire.t strain rate.de.e.de.ce.of strain re.istance.

A statistical ap.roach is de.e.op.0}, base. on a Monte.Carlo me.hod, in orde. to de.e.mine.the.statistical comp.sition of a p.lyamide.6 samp.e.comp.se. of cap.olactam （an AB-typ.0}monome.） and of a di-acid （A2 typ.0} or a tri- acid （A3 typ.0} as coup.ing age.ts. For this comp.sition, the.line.r the.logical be.avior of the.e.syste.s is p.e.icte. using a tube.base. the.ry. This allows us to show that while.coup.ing age.ts of typ.0}A2 can be.se.n as flow imp.ove., the.e.fe.t of branching age.ts of typ.0}A3, de.e.ding on the.synthe.is re.ip.0}and the.conve.sion le.e., can le.d e.the. to an incre.se.or to a de.re.se.of the.viscosity. By adding sp.0}ific amount of the.e.age.ts, we.also show that it is p.ssible.to obtain mate.ials with the.same.ze.o-she.r viscosity but with diffe.e.t she.r thinning be.avior. Furthe.more. the.p.lydisp.0}sity of line.r samp.e. of the.same.ave.age.numbe. mole.ular we.ght, Mn, is discusse. in function of the.amount of A2 monome.s the. contain.
