SCIENTIFIC-TECHNICAL SECTION

Senchenkov I. K., Chervinko O. P., Ryabtsev I. A., Kondratyev I. A. � Estimation method of the added metal thermal stability

Mathematical model and estimation method of the added metal thermal stability are developed. The method takes into consideration effect of the residual surfacing voltage and stress occurring at cyclic thermal load of the built up parts in the operating process on this parameter. It is established and experimentally backed that the designed mathematical model allows computing the parameter with sufficient degree of accuracy.
