Full Description
High Temperature Miniature Specimen Test Methods focuses on a comprehensive and thorough introduction to a range of high temperature, miniaturized test methods at elevated temperatures which are used to obtain "bulk” creep or fatigue properties from a small volume of material. The book will be of use to a wide range of audience of engineers (e.g., designers, manufacturers, metallurgists, stress analysts), researchers (e.g., materials scientists) and students (undergraduate and postgraduate) in the field of high-temperature material and structural integrity assessment. Specific novel features include 1] theoretical basis of each method; 2], data interpretation method of each test, and 3] specific applications.
Contents
1. Outlines test types and data processing used to estimate the material constants
2. The most popular small punch test method, i.e. the small punch test
3. Introduces the impression creep test method using a rectangular indenter
4. Theoretical methods for data interpretation and typical test data are described
5. These include the miniature ring creep test methods
6. The miniature bar-type creep test method
7. Miniature bending creep tests
8. The more recently developed miniature thin-plate test creep and low cycle fatigue test methods
9. A specific topic related to the data interpretation is addressed in this chapter, in which the concept of the Equivalent Gauge Length (EGL) is introduced
10. The determination of material properties from the miniature specimen
11. Focuses on a specific application field on structural assessment of aero-engine gas turbine blades, where the assessment of anisotropy and lifing of service-aged gas turbine blades made of single-crystal nickel-based superalloy is particularly discussed
12. Briefly addresses several requirements for the future development of the miniaturized specimen test method, which is related to material property characterization, component assessment, size effect and multi-scale modelling, as well as standardization
