1 noun interpretation elongation
Tensile elongation after fracture specimens i.e. gauge total deformation [Delta] L of the original gauge length L of the ratio of the percentage of segments: δ = ΔL / L × 100 percentage.
engineering materials often referred to as the percentage δ≥5 plastic material, such as dead load of normal mild steel, aluminum, copper or the like; and the percentage of the material is referred δ≤5 brittle material, such as room temperature static load of cast iron, glass, ceramics and so on.
Elongation divided into fixed multiple A5, A10 and the scaling in different ways of measuring the distance A50, A80, A100 and the like. A5 is the ratio of the original specimen gauge length to diameter ratio of 5, A10 is the ratio of the original specimen gauge length to diameter ratio of 10; A50 non-proportional sample of the original gauge length is 50mm, A80, A100 with empathy.
Third Generation automotive steel hot rolled coil and cold rolled sheet, high volume plastic are more than 30GPa percentage (tensile strength of 900MPa class time, elongation of 35 percent) than the first generation automobiles quadrupling steel, alloy content and not to 1/3 of a second-generation automotive steel.
Roewe 1.8T Kavachi maximum power of the engine is 118kw, using aerospace aluminum, the surface hardness of 110HB, tensile strength of the first domestic 330MPa, elongation overall up to 5 percentage -7 percentage is much higher than 2 percentage -3 percentage of the domestic like product, in the absolute leader.
