METHOD OF PREDICTING CREEP RUPTURE LIFE OF COMPOSITE METAL MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a method of predicting a creep rupture life of a composite metal molding easily and precisely without performing any complex calculation by considering variation of the creep rupture life of an actual composite metal molding.;SOLUTION: Data on a creep rupture life T are totaled for each occurrence location of a creep rupture; a natural logarithm value lnT is calculated from the creep rupture life T for the data on each occurrence location; an average value μ of lnT is obtained; expμ is calculated from μ and an average value TAVG of the creep rupture life is derived; and the creep rupture life of the composite metal molding is predicted based on a value of TAVG.;COPYRIGHT: (C)2011,JPO&INPIT
