Introduction to Hardness Testing ASM International

Hardness Testing Theory Early methods generally consisted of scratching. Scratch hardness testing consists of penetration of the material surface by a testing point and bears a close resemblance to the indentation hardness test. One of the earliest forms of scratch testing goes back to Reaumur in 1722. His scale of testing con-

Sand testing SlideShare

Dec 22 2017 The resistance of the dry sand core is called the core hardness. To test the harness the hardness tester is pressed onto the hard-flat surface of sand specimen until the anvil plate which surrounded by the probe makes even contact with the surface. Then the tester is presses firmly down on to any flat surface of a mould until the anvil plate .

Simulation of Sand Core Making Processes Validations and

For the hardening of the sand core the water must be removed from the core which is typically accomplished by the injection of hot air. For these binder systems the residual moisture in the core is a measure for the hardness. The simulation has to model not only the air flow through the core but also the evaporation and condensation of the .
