Investigation on Thermal Stress-Strain State in Multilayered Composites during Nickel Aluminide Coatings Formation
Authors: , , ,
Abstract: In this study multi-layered steel-nickel-aluminum composite with intermetallic interlayers was obtained using complex process which included explosion welding and heat treatment. Strength properties of the diffusion NiAl3+Ni2Al3 interlayer under thermal stress were investigated. The thickness value of diffusion interlayer as well as thickness ratios of composites components contributing to the rupture of the intermetallic interlayer during thermal loading were identified via standard method and verified using FEM simulation. The calculated results correspond with the experimental investigations. The interlayer rupture resulted in the formation of Ni/Ni2Al3 coating on steel.
