Early Detection of Damage of Inconel 718 with the Use of Strain-Hardening Cross-Effect

Indentation tests were used for early detection of deformation-induced damage Inconel 718. Damage was produced in a controlled manner using specially designed specimens with variable width the gage part. Static tension, LCF, and HCF performed to induce material damage. Accumulated plastic strain intensity as reference measure Detection progress its phase based on use strain-hardening cross-effect. Experimentally determined correlation hardness indentation work parameter analyzed. The results our analysis lead conclusion that proposed experimental procedure is useful stage process.
