一、 空间点阵与晶体结构有何关系?(15 分) 答: (1)晶体结构:晶体中原子(或离子、分子、原子集团)在三维 空间中有规律的周期性的重复排列方式。 实际存在的晶体结构是无限 的。 (2)空间点阵: 将构成晶体的实际质点抽象为纯粹的几何阵点, 这种阵点有规则地周期性重复排列所形成的空间几何图形即称为空间 点阵。空间点阵只有 14 种类型。 (3) 晶体结构与空间点阵的区别: 具有相同点阵但不同晶体结构, 具有相同晶体结构但点阵不同。 二、 已知纯铜滑移系的临界分切应力为 1MPa,若使(111)晶面上的位错 沿[101]方向滑移,需要在 [001]方向上施加的最小应力是多少?(15 分) 答: 设需要在[001]方向上施加的最小应力为 σ ,σ 在 (111)晶面 上的分切应力为 τ ,则有

τ =σ cosλ cosφ
k=1MPa,所以

已知纯铜滑移系的临界分切应力 τ

σ =τ

(15 分) 答:影响再结晶温度的因素主要有: (1)变形程度:金属冷变形程度增大,储存能提高,再结晶驱动 力增大,再结晶温度降低。 (2)金属纯度:金属中的杂质或合金元素能阻碍位错运动和晶界 迁移,所以金属纯度越高,再结晶温度越低。 (3)原始晶粒尺寸:原始晶粒尺寸细小,变形抗力较大,冷变形 后金属储存能较高,再结晶温度较低。 (4)加热时间和加热速度:加热时间增加,再结晶温度降低;加 热速度提高,再结晶温度提高。 控制再晶晶粒的大小的方法 (1)变形程度:变形量很小时,不发生再结晶。变形量达到一定 程度时(一般为 2-10%) ,再结晶晶粒特别粗大。这样的变形度称为临 界变形度。原因:变形量小,再结晶核心少,生长速度却很大。大于临 界变形度后,晶粒尺寸随变形量的增加而下降。 (2)原始晶粒尺寸:原始晶粒尺寸细小,再结晶形核位置增多, 再结晶晶粒细小。 (3)杂质与合金元素:杂质与合金元素提高变形抗力和储存能, 阻碍晶界移动,细化再结晶晶粒。 (4)变形温度:变形温度越高,回复程度越大,储存能越小,再 结晶晶粒越粗大。 (5)退火温度:在退火保温时间一定时,再结晶退火温度越高,

(1)奥氏体的形核。奥氏体晶核通常优先在珠光体的铁素体与渗碳 体的相界面上形成,相界面越多,奥氏体晶核越多。 (2)奥氏体的长大。奥氏体晶核形成后,它的一侧与渗碳体相接, 另一侧与铁素体相接。随着铁素体的转变(铁素体区域的缩小) ,以 及渗碳体的溶解(渗碳体区域缩小) ,奥氏体不断向其两侧的原铁素 体区域及渗碳体区域扩展长大,直至铁素体完全消失,奥氏体彼此 相遇,形成一个个的奥氏体晶粒。 (3)剩余渗碳体的溶解。铁素体完全消失后,随着保温时间延长或 继续升温,“剩余渗碳体”全部溶入奥氏体,奥氏体的成分达到共 析成分。 (4)奥氏体成分的均匀化。即使渗碳体全部溶解,奥氏体内的碳浓 度仍不均匀,原渗碳体区域形成的奥氏体含碳量偏高,继续保温时 间延长或继续升温,让碳原子充分扩散,奥氏体成分才可能均匀。 影响转变速度的因素:加热温度、原始组织、化学成分
