Metallographic Abrasive Grinding

Grinding/polishing pressure is dependent upon the applied force (pounds or Newtons) and the area of the specimen and mounting material. Pressure is defined as the Force/Area (psi, N/m 2 or Pa). For specimens significantly harder than the mounting compound, pressure is better defined as the force divided by the specimen surface area.

Metallurgical Reasons for Grinding Cracks and Their

Mechanical effects and proper grinding result in a compressive residual stress at the surface. This is beneficial for fatigue. Thermal effect produces the opposite effect, with a residual tensile field at the surface. As the part is locally heated, the surface layer expands, but it is constrained by the lower undisturbed material.
