In this paper, the interface microstructure, elements’ diffusion features at the interface, and bonding properties in nickel-based alloy/carbon steel clad composite prepared by vacuum hot-roll bonding were investigated, comprehensively. The influence of element distribution on the interface bonding strength was revealed as well. The results showed that there was a 13 μm thick diffusion layer at the interface of nickel-based alloy/carbon steel composite plate, which was beneficial to a strong bond between nickel-based alloy and carbon steel, as well as the stable transition of mechanical properties in the thickness direction. Kirkendall voids and fine-grained structure (the grain size is about 41.5 nm) were observable by peeling off the nickel-based alloy cladding, which greatly promoted element diffusion and enhanced the interfacial bonding strength of the nickel-based alloy/carbon steel composite plate. The diffusion coefficient of Ni at the interface was about 2 orders of magnitude larger than that of nanocrystalline Fe. The shear strength reached up to 453 MPa, which was much higher than the minimum of 140 MPa defined in ASTM A-264 specifications. Furthermore, in the shear test, the fracture occurred on the X52 carbon steel side at the contact rather than at the composite plate interface.

This paper compares the microstructure and mechanical evolution in a high-strength quenched and micro-alloyed steel during the austenitising bending process. Simulation results indicated a new finding that the stress neutral layer (SNL) tends to move to the tension zone during straining. The hardness gradient detected from the centre to compression/tension zones was resulted from comprehensive factors: First of all, the location of SNL revealed a prominent impact on strength. Second, the dislocation accumulation would be responsible for the hardness gradient on the surfaces. In addition, the overall strength decrease during straining was mainly ascribed to integrated effects of dynamic recovery (DRV) and dynamic recrystallisation (DRX). Apart from that, overall smaller martensite packet size and coarser prior austenite grains resulted in the increased hardness value at a lower bending degree. Also, the high consistency between experimental and simulation results is instructive for the practical forming process of railway spring fasteners.

Hot stamping is an advanced forming process used in automobile lightweight manufacturing, but it has not been used in the manufacture of bimetal composite parts. In this work, based on the hot stamping forming technology and the advantages of bimetal composite in strength, stiffness and corrosion resistance, the finite element simulation theoretical analysis and test on the hot stamping forming of AA6061/Q345 bimetal composite U-shaped parts were performed. The effect of initial temperature, stamping speed, die gap and pressure holding time on forming quality were investigated. The results show that the initial temperature not only affects the temperature distribution of each layer of the bimetal composite after stamping but also affects the deformation resistance during forming. The increasing stamping speed reduces the contact time between the die and plate rising the plate temperature, but the increasing stamping speed also strengthens the stamping hardening effect in the forming process leading to the stress increase. The die gap affects the contact area between the plate and the die. The increasing gap is beneficial to reduce the temperature difference between different layers. However, an excessive die gap also increases the tensile stress in the plate and affects the forming accuracy. With the pressure holding time larger, the temperature of the formed part becomes low, the residual stress releasing causes the stress to be smaller. According to the analysis of tensile and bending mechanical properties, it is indicated that the formed parts prepared by the optimal parameters obtained by numerical simulations have excellent mechanical properties and formability.
