Download or read book Development of Methods and Instruments for Mechanical Evaluation of Refractory Materials at Very High Temperatures written by Delbert H. Fisher and published by . This book was released on 1961 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A system has been developed for determining the conventional mechanical properties of materials at temperatures up to 4000 F in vacuum. Techniques for obtaining stress-strain properties in tension and compression are described in this report. Strains are measured optically directly at the gate section to an accuracy of plus or minus 50 microinches per inch in a 2-inch gage section. An evaluation of the system was made using a Mo-0.5Ti bar material. Exploratory work was conducted on graphite and a refractory sheet metal. The results for these tests are included in the report. With the objective of developing a temperature source for use above 4000 F, experiments were conducted to produce and to evaluate tantalum carbide-coated graphite heaters. Good coatings of tantalum carbide were produced both on thin-wall cylindrical heaters and on spiral heaters. It was found that carbon contamination of the atmosphere occurred such that tungsten shields of tungsten specimens were attacked at temperatures under 5400 F. Possible means of improving carbide coatings are suggested.

This book was released on 1948 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: "One of the most important properties of refractory materials is the ability to resist stress which may either be directly applied or originate in the material. The factors which govern the resistance to stress include the modulus of elasticity, the ultimate strength under different types of stress, and the "flow" characteristics which become of importance when the material is stressed at the temperature at which plasticity is developed. Systematic determinations of the mechanical properties such as modulus of elasticity and ultimate or breaking stress is rather difficult or more or less impossible to carry out at the temperature at which the refractories are used"--Introduction, leaf 1.
