چکیده مقاله
Due to the increasing development of additive manufacturing AM in manufacturing and production, especially in sensitive and advanced industries, such as aerospace, military and automotive industries and the numerous uses of this technique for the production of titanium parts, this study tries to The results of changes in one of the most effective factors in the production process on the mechanical properties of titanium alloy coupon Ti Al6 4V to be presented by the digital image correlation technique Due to the wide application of SLM technique in production methods of additive manufacturing of steel structures, changing the effective production parameter of the effect of laser beam overlap on mechanical properties, including; The final yield strength, the percentage of elongation of the produced parts and the effect of laser energy density on the changes in mechanical properties have been investigated The technique used toextract the mechanical properties is also digital image correlation DIC of optical and non contact methods in part surface inspection Due to the fact that the overlap distance indicates the penetration of two laser beams along the part, its non penetration causes undiluted powder remaining in the fabrication process and its excessive penetration also causes gas cavities and thus porosity in the part Becomes final Therefore, for optimal product production, there is an optimal value for the parameter
