Selection of criteria for interchangeability verification of special alloys on the example of nimonic
Research of nimonic long-term strength, which allows determining its value at different temperatures and the test of time are conducted on the basis of mathematical simulation. Criterion for interchangeability verification of special alloys on the example of nimonic is proposed. This criterion is based on a parametric description of the test property depending on the Lagrange multiplier and allows finding its suboptimal values in the investi- gated range of input variables
