本研究报告的目的如下：(1)从sae1008钢中生产标称纯度的铁素体；(2)培养该材料的单晶，其尺寸适合于随后的张力试验；(3)找出滑移和孪晶的临界分解剪应力，只要它们可以确定为温度的函数；(4)确定是否发生从滑移到孪生的转变，并具有结果的可重复性，以及是否可以建立孪生发生的标准；(5)研究单晶断裂性能随温度、应变、时效和预应变的变化规律。(6)用高分辨能力的方法，如电子显微镜，研究铁中滑动的原子性质。b.多光束干涉测量法和(7)在λ -铁的一般变形理论中将上述内容联系起来。
The objectives of this investigation reported herein are as follows: (1) To produce a ferrite of nominal purity from SAE 1008 steel; (2) To grow single crystals of this material of a size suitable for subsequent tension tests; (3) To find the critical resolved shear stresses for slip and twinning insofar as they can be determined as a function of temperature; (4) To determine whether a transition from slip to twinning occurs with reproducibility of results and whether a criterion for the onset of twinning can be established; (5) To study the fracture properties of single crystals as a function of temperature, strain, aging, and prestrain. (6) To investigate the atomic nature of slip in iron by methods of higher resolving power, e.g., a. The electron microscope. b. Multiple beam interferometry and (7) To correlate the above in a general theory of deformation for lambda-iron.
