Abstract Fracture behavior of Al-Mn alloy after plastic deformation is studied by electron microscopy. Cracked can mainly caused the lamination Al-Mg plate. Optimized melt treatment main way to solve problem microporosity. Microporosity be eliminated adjusting casting speed and other technological parameters. As a result, during weakened. The rate cracked cans in process reduced subsequently.

In the same paper, by using the result above, he proposes a procedure for determining whether a given manifold contains an essential lamination or not. However the procedure does not work, at present, since (1) there is not a practical algorithm for determining whether a given branched surface is essential or not, and (2) there does not exist an algorithm for determining whether a given branche...

Abstract. We consider statistical mechanics systems defined on a set with some symmetry properties (namely, the set admits an action by a group, which is finitely generated and residually finite). Each of the sites has a real order parameter. We assume that the interaction is ferromagnetic as well as symmetric with respect to the action of the symmetry group as well as invariant under the addit...

We study the structure of a class of laminar closed positive currents on CP, naturally appearing in birational dynamics. We prove such a current admits natural non intersecting leaves, that are closed under analytic continuation. As a consequence it can be seen as a foliation cycle a weak lamination.

We introduce the notion of “slope” for geodesic laminations. Slope is a positive irrational defined via regular continued fraction. The action of the mapping class group on lamination pulls back to the action of GL(2, Z) on real line. We discuss applications of slopes in complex analysis, low-dimensional topology, geometric group theory and C∗-algebras.
