延展性 Ductility

（重定向自Ductile）

在拉伸试验后，不同金属材料产生不同的破断面.
(a)脆性破裂
(b)中等延性破裂
(c)高延性破裂

延展性（ductility and malleability），是物质的一种机械性质，表示材料在受力而产生破裂（fracture）之前，其塑性变形的能力。延展性是由延性、展性两个概念相近的机械性质合称。常见金属及许多合金均有延展性。

在材料科学中，延性（Ductility）是材料受到拉伸应力（tensile stress）变形时，特别被注目的材料能力。延性它主要表现在材料被拉伸成线条状时。展性（Malleability）是另外一个较相似的概念，但它表示为材料受到压缩应力（compressive stress）变形，而不破裂的能力。展性主要表现在材料受到锻造或轧制成薄板时。延性和展性两者间并不总是相关，如黄金具有良好的延性和展性，但铅仅仅有良好的展性而已。然而，通常上因这两个性质概念相近，常被称为延展性。

The local necking and the cup and cone fracture surfaces are typical for ductile metals.$ $Schematic appearance of round metal bars after tensile testing. (a) Brittle fracture (b) Ductile fracture (c) Completely ductile fracture$ In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire. Malleability, a similar property, is a material's ability to deform under compressive stress; this is often characterized by the material's ability to form a thin sheet by hammering or rolling. Both of these mechanical properties are aspects of plasticity, the extent to which a solid material can be plastically deformed without fracture. Also, these material properties are dependent on temperature and pressure (investigated by Percy Williams Bridgman as part of his Nobel Prize-winning work on high pressures). 近义、反义、联想词近义词 adj. tractable, manipulable, formed 反义词 n. intractable, unformed 联想词 tensile拉力的;deformation损形;brittle易碎的，脆弱的;alloy合金;thermoplastic热后可塑性的;steel钢铁;molten熔化的;alloys合金;extruded压出的;refractory执拗的,倔强的,难驾驭的;corrosion腐蚀; 英英词典 ductile adj. easily influenced synonymous： malleable capable of being shaped or bent or drawn out ductile copper synonymous： malleable, pliable, pliant, tensile, tractile
