补充资料:屈服
屈服
yield
屈服yield在外加应力下,材料开始发生不可逆的范性变形的现象。连续加载过程中,应力不增加或开始有所降低而材料如能继续变形,这种材料便具有明显的屈服现象,此时材料所承受的恒定、最大或最小应力分别称为材料的屈服点(飞)、上屈服点(隽u)或下屈服点(asL)。低碳钢及其他含有少量填隙元素的体心立方金属等都具有明显的屈服点:而不锈钢、面心立方金属及密集六角结构金属则无明显的屈服点。对于没有明显屈服现象的材料,很难准确测定它们发生塑性流变的起始点,工程上一般取永久变形值达0.2%时所对应的应力值为该材料的屈服强度,以a02表示。 屈服现象与材料中位错的形成、增殖及运动有关。体心立方金属中位错受到钉扎,不易运动,而且位错的运动速率对应力不敏感,可滑移位错的形成便标志着范性形变的开始,因而具有明显的屈服点。而面心立方金属中位错的运动速率对应力非常敏感,原生位错在低应力下就能运功,使面心立方金属不存在明显的屈服点。 (李宗全)
