The impact of hydrogen on the ductility loss of bainitic Fe–C alloys [PDF]

open access: yes, 2016
The influence of hydrogen on the mechanical properties of generic lab-cast Fe-C bainitic alloys is studied by tensile tests on notched samples. The bainitic microstructure is induced in a 0.2% C and 0.4% C Fe-C alloy by an appropriate heat treatment. The

Very High Cycle Fatigue Damage of TC21 Titanium Alloy under High/Low Two-Step Stress Loading

open access: yesCrystals, 2023
Very high cycle fatigue (VHCF) tests were carried out under variable amplitude loading for TC21 titanium alloy. The first level of high amplitude loading was set as 950 MPa close to yield strength, and the second level of low amplitude loading was ...

A spectrophotometric method for measuring the breakdown of hydrogen peroxide by catalase.

open access: yesJournal of Biological Chemistry, 1952
Several methods have been developed for following the breakdown of hydrogen peroxide catalyzed by catalase, but these either have not been sufficiently quantitative or have not proved rapid enough to yield reliable data during the critical 1st or 2nd ...

Mechano-chemical Synthesis of NaAlH4: Optimization of Reaction Conditions

open access: yesMATEC Web of Conferences, 2016
NaAlH4 was mechano-chemically synthesized with high energy ball-milling method. The effect of synthesis conditions such as milling time, H2 pressure, chloride catalysts, and solvents was investigated to enhance the synthesis of NaAlH4. Among the chloride
