The aim of this work is to offer a quantitative assessment as to what extent the texture and the microstructure influence the cold headability of steel wires. / For this, a set of cold drawn low carbon steel wires/AISI 1030 were prepared. The samples were drawn, without heat treatment, in between passes of up to 78% reduction in area (RA) in 5 passes. The deformed samples were then heat treated according to various schedules. / Texture development was studied at a given thickness, by measuring the (110), (200) and (211) pole figures by X-ray diffraction; furthermore, the results were represented and using the Orientation Distribution Function (ODF). A strong $ langle$110$ rangle$ texture was found. / Using special dies, compression tests were made in order to obtain information on such mechanical properties as the yield strength and the homogeneous strain energy. / Multiple regression analysis was made in order to correlate the aspect ratio, the grain size, the Taylor factor and the maximum ODF intensity against the yield strength and the homogeneous strain energy.
