Instead of measuring the elasticity of steel by a tensile test, is there any formula that relates the hardness of steel to the elasticity limit?
Use a hardness tester to measure the steel's elasticity limit
see:
DIN EN ISO 18265:2014-02 (Metallic materials - Conversion of hardness values (ISO 18265:2013); German version EN ISO 18265:2013)
GOST 22761-77 (Metals and alloys. Method of measuring Brinell hardness by static action portable hardness meters)
Approximate correlation: tensile strength (MPa) = 10HB/3
For low carbon and low alloy steels the relation between tensile stress and Brinell Hardness is 0,308.
Is DCFDA appropriate for measuring total ROS production, or can it only detect certain types of ROS? If I want to measure total ROS production, which dye should I use?
