本文确定了晶带轴[011]γ经一次切变后的指数为[277]γ。证明:γ-Fe 在一次切变时,[211]γ转至[111]γ 的角度为 19°28′,[011]γ转至[277]γ的角度为 11°24′;1.4％C 钢的二次切变角为 9°;γ-Fe二次切变所在晶面于一次切变前为(131)γ,于一次切变后为(121)γ。指出 γ-Fe 也需要晶格调整步骤而且调整中各晶面及晶向间的角度不变。补充出相变获得的马氏体晶胞,并建立起体心直立六面体与马氏体晶胞的关系图。
In this paper, we determine the index [277] γ of the crystal axis [011] γ after a single shear. It is proved that the angle of [211] γ to [111] γ is 19 ° 28 ’at [211] γ to [277] and the angle of γ is 11 ° 24’; 1.4% C The secondary shearing angle of steel is 9 °. The surface of γ-Fe secondary shearing is (131) γ before one shearing, and is (121) γ after one shearing. It is pointed out that γ-Fe also needs a lattice adjustment step and the angle between crystal planes and crystal orientations in the adjustment is not changed. Complementing the martensitic unit cells obtained by the phase transformation, and establishing a relationship between the body center upright hexahedron and the martensite unit cell.
