导出了多族晶面迹线夹角的计算公式,由之可以确定在接近零倾动时任何晶系一定取向的薄晶中多族迹线所由产生的晶面族。通过对GH36合金晶间VC薄膜中滑移痕迹的分析和位错切割通过VC粒子的强化机制的确定,对Cr27铸铁中马氏体孪晶和高次孪晶的详尽分析及M_7C_3中{013}孪晶的发现,证明这是一种可取的严密计算方法。
The formula for calculating the included angle of multi-family crystal plane trace is deduced, which can be used to determine the family of crystal planes generated by the multi-family trace in the thin crystal with orientation of any crystal system close to zero tilt. Through the analysis of the gliding traces in VC films of GH36 alloy and the dislocation cutting, the detailed analysis of martensite twins and high-order twins in Cr27 cast iron and the determination of {013} The discovery of twins proves that this is a desirable method of rigorous calculation.
