Hydrogen Decrepitation
Then why would you want to introduce hydrogen into a metal? Because we can use the same property to achieve our goal of reducing the grain size.

Neodymium magnets are made by a sophisticated process that includes some very high-tech metallurgical methods comprising powder metallurgy and advanced process metallurgy.
Dozens of process steps must be followed very precisely to make Neodymium magnets –also known as NdFeB -for the chemical symbols of Neodymium, Iron and Boron.
Small NdFeB Magnets in SmartphonesNeodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. These internal magnets are typically used in the speaker, receiver, vibration mode motor, taptic feedback motor, and camera auto-focus mechanism. […]
When we apply an outside magnetic field to a magnetic material, we are forcing it -coercing it- to become magnetized. Now that it is magnetized, how much of an applied field is required to demagnetize the material? When we measure the applied field that either magnetizes or demagnetizes the material, we measure the Coercivity of […]
Remanence is the remaining magnetic field found in the material after the applied magnetic field is reduced to zero. Remanence is derived from the same word as “remainder” or “remaining” so we can think of Remanence as the magnetic field that remains in the material after the outside magnetic field has been released.Remanence is also […]
Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field. If a material’s internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material. If the material’s internal dipoles do not become easily oriented to an applied magnetic field, it is […]
A BH Curve is a graph of the Hysteresis of a magnetic material. Hysteresis is how the material reacts to external magnetic forces. Magnetic materials always resist the external magnetic force to some extent. That extent tells us a lot about the material’s own magnetic properties.
