Microstructure and Strength of Explosively Welded Titanium/Ni-Based Alloy Composite with Cu/Ta as Interlayer

Abstract: In current research composite copper/tantalum were used as interlayer for explosive welding of titanium and Ni-based alloy sheets. Defects such as cracks coupled with brittle intermetallics compounds were not detected at the interface of dissimilar materials by metallographic analysis. Strength test of obtained composite material reveals growth of yield strength in 2 times in comparison with Ni-based alloy.

“…Such layers are used to limit the interaction of fabricated materials, which leads to deterioration in the performance properties of compositions. The use of inserts showed an especially effective result during the welding of dissimilar materials with a great difference in physical properties prone to the formation of chemical compounds having low fracture toughness and impact strength [16][17][18][19][20][21][22][23][24]. Nickel and copper layers can be distinguished among the most commonly used intermediate layers.…”

“…Полностью исключить образование в зоне сварного соединения хрупких интерметаллидов, отрицательно влияющих на комплекс механических характеристик композиции, невозможно. В некоторых случаях с целью повышения качества сварных швов и соответствующего улучшения комплекса механических свойств получаемых материалов предлагается использовать промежуточные вставки, состоящие из материалов двух типов [15][16][17]. Применение при сварке технически чистого титана ВТ1-0 и хромоникелевой стали 12Х18Н10Т композитной вставки «тантал -медь», полученной по технологии сварки взрывом, обеспечило предел прочности сварного соединения на уровне 420 МПа [17].…”
