The application of non-destructive test methods in quality control of semi-finished and finished products is of maximum economic importance in modern industry. The development of the eddy ...

In order to evaluate the wear characteristics it is advantageous to use a nondestructive method for measuring the thickness of the hardened surface layer, that is hardness depth ...

It is a matter of choice whether the ultrasonic testing of safety parts takes place on-line or off-line. Longitudinal and transverse flaws, internal and external flaws, such as shrink-holes, cracks, and ...

The magneto-inductive method is ideally suitable for automatic 100% testing. Such characteristics as the surface hardness and case hardening depth can be verified without destruction using this ...

The hardness of a material is a poorly defined term which has many meanings depending upon the experience of the person involved. In general, hardness usually implies a resistance to deformation ...

Charpy impact test method for metallic materials is specified by European EN 10045 standard. This specification defines terms, dimension and tolerances of test pieces, type of the notch (U or V), test force, verification of impact ...

Aircraft and chemical processing equipment are now required to work at subzero temperatures and the behavior of metals at temperatures down to -150掳C needs consideration, especially from the point ...

The engineering tension test is widely used to provide basic design information on the strength of materials and as an acceptance test for the specification of materials. In the tension test a specimen is subjected to a ...

Modern railway systems are subjected to intense use, with fast trains and increasing axle loads. Rails have to be more wear resistant and achieve higher standards of straightness...

When we speak of 鈥渕agnetic behavior鈥�, we usually mean ferromagnetic behavior. Actually there are two other types of magnetic behavior: diamagnetic behavior, which...
