Structure and properties of deposited metal of die steel type

摘要

Given are the results of investigation of the properties of deposited metal corresponding to chrome-molybdenum steel, additionally alloyed with niobium. It is shown that complex alloying leads to a significant increase of the heat-resistance of deposited metal. The results of investigation of structural transformations in the metal of 35Kh5B2FMS type with the different rates of heating and cooling, are described. On the basis of the results of investigations the recommendations are given on evaluation and selection of surfacing materials, as well as on heat-treatment of the deposited layer.
