Materials Engineering Kasteelpark Arenberg 44, B-3001 Heverlee, Belgium Keywords: ECAE, AA1050, fine-grained material, thermal stability, discontinuous grain growth Abstract.
Introduction The strength of metallic materials is improved by grain refinement.
Conclusions In order to produce fine-grained materials in the present CP-aluminium, at least 8 ECAE passes, route C, are necessary to get a homogeneous material and some post-annealing is recommended.

Introduction Chalcogenide glasses are vitreous materials which are composed of S, Se, and Te, from group-VI of the periodic table.
These materials have gained importance in technological fields [1].
Materials (99.999% purity) were weighed according to their atomic weight and sealed in quartz ampoules in a vacuum ~ 10-4 Pa.

Experimental Materials.
However, due to the nature of the method, it is not possible to control the amount of materials deposited.
Adhesion of the materials can be improved by the addition of a matrix to hold and trap the materials together.
Drop casting method involves depositing known volume or mass of materials onto bare graphite electrode, given that the suspension of materials is well-dispersed and well-mixed.
