An influence of the deformation rate at elevated temperatures on the degree of the mechanical property loss of the 45 steel covered with the Cd-Zn galvanic coatings

The article presents a short characteristic of the latent fracture. In the experimental part the degree of the immediate strength loss of the 45 steel covered with the galvanic coatings was determined in the function of the deformation rate. It has been found that a significant influence of the deformation rate on the degree of the immediate strength loss (Rm) of the 45 steel with the Ce-Zn galvanic coatings is visible below the rate of 2 x 10-3 s-1.
