The fracture strength of a brittle material, like a ceramic increases by increas

Question

The fracture strength of a brittle material, like a ceramic increases by increasing the number of internal cracks and notches, which may increase the resistance to fatigue of the material. T Crazing is a very localized plastic deformation in thermoplastic polymers. In a heat treated alloy the precipitate enhances the dislocation movement and thereby decreases the strength of the alloy. As Cold work increases yield strength and tensile strength decreases. Meta-stable state is a very slow, imperceptible change in structure with time. Metal parts subjected to repetitive stresses will fail due to fatigue loading at a much lower stress than that which the material can withstand under the application of a single static stress. Carburizing or nitriding (case hardening technique) enhances both surface hardness and fatigue life for steel alloys. Creep is a form of failure that occurs in structures subjected to dynamic and fluctuating stress. Plagiarism involves using the works of others and not giving due credit. It is a form of cheating or theft and should be avoided. Prior deformation of the metal, time and temperature affect the recrystallization process in metals and alloys.
