Diffusion bonding is a commonly used method to realise dissimilar materials joining, which is usually carried out at elevated temperature to ensure sufficient interdiffusion across the interface [4]. However, at relatively high temperatures, the bonded structure tends to undergo large deformation which could be detrimental to its precision. ...
