Bimetal or laminated metal composites consisting of several metal or alloy layers can efficiently absorb the advantageous properties of each metal when utilised as raw materials for future remanufacturing. Their mechanical response characteristics and failure modes face uncertain challenges during the processing owing to the existence of heterogenous interfacial transition zones between layers. This work aims to study the uncertainty quantification in bending processing of a novel bimetal composite as a result of uncertain interfacial zones using an efficient evidence-based reliability analysis method. An analytical model for bending characteristics of bimetal composite was first established based on the deterministic material properties of each component layer, and it was employed to quantitatively analyse the bending uncertainty properties of 2205 duplex stainless steel/AH36 carbon steel bimetal composite (2205/AH36 BC) considering the epistemic uncertainty in geometric dimensions an
The influence of annealing treatment on the mechanical properties and interfacial characteristics of a TA1/Al5083 bimetal composite was investigated in this research. The bimetal composite plates were prepared by explosive welding and annealing at temperatures ranging from 400 to 550 °C at intervals of 50 °C for 3 h. Uniaxial tensile and shear tests were employed to study the influence of the annealing treatments. Uniaxial tensile tests indicate that the tensile strength and elongation display a tendency to first improve and then decrease with increasing annealing temperature. No obvious necking phenomenon is observed in the composite sheet annealed at 400 and 450 °C, and extremely short cracks appear in the interfacial transition zone, while localized necking and delamination phenomena are found to occur in the composite sheet annealed at 500 and 550 °C. The ultimate tensile strength and elongation of specimens annealed at 450 and 500 °C is improved, while specimens annealed at 5
New Delhi [India], November 3 (ANI/Mediawire): Alstone, one of India's leading manufacturers of High-Pressure Laminate (HPL) & Fire rated Aluminum Composite Panel (ACP) in India, joined hands with VMZINC, France the world's largest zinc titanium rolled products and finished goods manufacturer in a recent event held in Delhi. The two conglomerates ALSTONE and VMZINC announced a "sustainable growth partnership " to manufacture Zinc composite panels and Zinc Honeycomb panels, which eventually becomes one of the biggest initiatives towards green metal being used in the Indian cladding industry. Zinc as a metal is eco-friendly due to its recyclability, longer life, and self-healing properties yet providing a beautiful aesthetician effect due to its naturally ever-changing appearance. This alliance provides a wide range of products for exterior cladding with FR-grade safety standards for commercial, institutional, and residential requirements while taking care of the ae
The interfacial zone formed in the manufacturing process of bimetal or laminated metal composites owes complicated microstructures and properties. This special feature greatly affects the fracture toughness and fatigue strength of metal composites. The crack growth behaviours, from a weak layer (AH36 carbon steel) to a strong layer (2205 duplex stainless steel), at the interfacial zone of a hot-rolled bimetal composite (2205/AH36 BC) were investigated. To clarify the potential factors altering the crack growth behaviour near the interface, the variations in fracture force under different loading speeds and directions were obtained from a well-designed micro tensile machine. The results indicate that the influence of crack propagation direction on the tensile fracture force when passing through the interfacial zone is greater than the force at the initial notch of crack. The tension loading speed determines the shielding or amplification effect on the crack tip, verified by the microstr
