Biomass power plants with high efficiency are desired as a renewable energy resource. High efficiency can be obtained by increasing temperature and pressure. An upgrade of the material performance to high temperature material is therefore required in order to meet the increased demands due to the higher temperature and the more corrosive environment. In this study, the material’s high-temperatu...

The hydrogen embrittlement susceptibility of two precipitation hardened nickel-based alloys was studied. Conventional slow strain rate testing results are compared against data obtained from a modified Rising Step Loading Test with interrupted charging to determine the role defects in passive layer caused by local straining. these tests, show that elongation failure for most cases independent m...

39SiCrVTiA spring steel is heat-treated and compared with the existing high-strength steels 60Si2CrVA SAE9254 for electrochemical impedance spectroscopy (EIS), polarization curve slow strain rate testing (SSRT). The test results of show that corrosion resistance was best, followed by 39SiCrVTIA.However, SSRT three in 5% NaCl solution possess high SCC susceptibility. susceptibility slightly lowe...

fiber reinforced composites are widely used instead of traditional materials in various technological applications. therefore, by considering the extensive applications of these materials, a proper knowledge of their impact behavior (from low- to high-velocity) as well as their static behavior is necessary. in order to study the effects of strain rates on the behavior of these materials, specia...

experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304h stainless steel. three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the drx critical strain: strongly strain dependent softening by srx alone with softening kinetics control...

the consolidation test method proposed by terzaghi and used in most soil mechanic laboratories has limitations and weaknesses. to get correct results, improvement and modification of the test method is essential. several experimental methods, such as constant loading rate, gradient and constant rate of strain (crs) have been used over the past 40 years. of these methods, crs is more advantageou...
