Characterizing the Tensile Behavior of Double Wire-Feed Electron Beam Additive Manufactured “Copper–Steel” Using Digital Image Correlation

The paper presents the results of the evaluation of the mechanical characteristics of samples of multi-metal “copper-steel” structures fabricated by additive double wire electron beam method. The global and local mechanical characteristics were evaluated using uniaxial tensile tests and full-field t...

description The paper presents the results of the evaluation of the mechanical characteristics of samples of multi-metal “copper-steel” structures fabricated by additive double wire electron beam method. The global and local mechanical characteristics were evaluated using uniaxial tensile tests and full-field two-dimensional digital image correlation (DIC) method. DIC revealed the peculiarities of the fracture stages: at the first stage <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mo stretchy="false">(</mo><mn>0.02</mn><mo><</mo><mi>ε</mi><mo>≤</mo><mn>0.08</mn><mo stretchy="false">)</mo></mrow></semantics></math></inline-formula> the formation of V-shaped shear lines occurs; at the second stage <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mo stretchy="false">(</mo><mn>0.08</mn><mo><</mo><mi>ε</mi><mo>≤</mo><mn>0.15</mn><mo stretchy="false">)</mo></mrow></semantics></math></inline-formula> transverse shear lines lead to the formation of a block structure; at the third stage <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mo stretchy="false">(</mo><mn>0.15</mn><mo><</mo><mi>ε</mi><mo>≤</mo><mn>0.21</mn><mo stretchy="false">)</mo></mrow></semantics></math></inline-formula> the plasticity resource ends in the central part of the two necks cracks are formed, and the main crack is the cause of the fracture of the joint. It is found that shear lines are formed first in copper and then propagate to steel.
