71Recrystallization (metallurgy) — Recrystallization is a process by which deformed grains are replaced by a new set of undeformed grains that nucleate and grow until the original grains have been entirely consumed. Recrystallization is usually accompanied by a reduction in the… …
72Hardness — This article is about mechanical properties of materials. For other uses, see Hard. Hardness is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. Macroscopic hardness is generally… …

74Embrittlement — is a loss of ductility of a material, making it brittle. Various materials have different mechanisms of embrittlement.* Hydrogen embrittlement is the effect of hydrogen absorption on some metals and alloys.* Sulfide stress cracking is the… …
75Fiber reinforced concrete — (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. Fibers include steel fibers, glass fibers, synthetic fibers and… …
76Aermet — special ultra high strength type of martensiticFact|date=August 2008 steel. The main alloying elements are cobalt and nickel, but chromium, molybdenum, and carbon are also added. Its exceptional properties are hardness, tensile strength, fracture …
77Fracture toughening mechanisms — In materials science, fracture toughening mechanisms are processes that increase energy absorption during fracture, resulting in higher fracture toughness.Intrinsic toughening mechanismsIntrinsic toughening mechanisms involve a fundamental change …
78Austempering — is a hardening process that is used on metals to promote better mechanical properties.These properties include: * Higher ductility * Resistance to shock * Uniform HardnessThe ProcessThe metal is heated into the austenite region and then… …
79Heissriss — Ein Heißriss ist eine Beschädigung des Werkstückes während eines Schweißvorganges. Der Riss entsteht während der Erstarrung (im Gegensatz zu Kaltrissen) bei Temperaturen, die zwischen der Solidus und der Liquidustemperatur liegen und ist damit… …
80Restaustenit — ist eine bei der konventionellen Stahlvergütung meist unerwünschte Phase im Stahl oder Gusseisen. Sie ist relativ instabil und wandelt sich durch Temperaturerhöhung in Ferrit und Zementit, und bei Temperatursenkung sowie durch mechanische… …
