摘要
The mechanical behavior of commercial purity Ti (CP-Ti)/Ti-6Al-2Zr-1Mo-1 V structurally graded materials (SGMs) fabricated by laser additive manufacturing was investigated via uniaxial tensile experiments. Although the strength of all SGM specimens is higher than that of the monolithic CP-Ti specimens, only the SGM specimen of 010 mm gauge diameter with bulky a-grains exhibits excellent plasticity comparable to the CP-Ti specimen under the same conditions. The SGM presents a potential for use as load-bearing components due to its good strength ductility balance. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
