The crystallographic texture and properties of metal materials, received by the PDME-method

The researches of polycrystalline materials received by the PDME-method as ribbons are carried out. The crystallographic textures of aluminum material s (as example) are investigated in nine layers on thickness with help of th e X-ray diffraction and then ODFs of them are reconstructed The general sin gularity approximation of random fields is used for the evaluation of effec tive elastic modulus and parameters of anisotropy of these layers. On the o ther hand for each layers it is possible to calculate velocities of melt co oling. It allows to connect values of the velocity of cooling with the stru cture and properties of investigated layers. The connection between velocit ies of cooling of a melt and elastic properties of rapidly quenched materia ls and crystallographic textures of materials is established as the theoret ical model based on initial experimental data. The results are presented by the figures. (C) 2001 Elsevier Science B.V. All rights reserved.
