【摘要】 利用透射电子显微镜和计算机图像模拟技术研究了Ll型Ａｌ３Ｔｉ合金室温变形的位错核心结构，结果表明：ａ（１１０）超位错在｛１１１｝面上分解成两个ａ／３（１１２）型超偏位错，其间为超点阵内禀层错更多还原

【Abstract】 TEM investigation associated with computer image simulations were conducted to determine the dissociation of superdislocations in the room temperature deformed Ll2-type Al3Ti alloy.It is determined that the a(110) superdislocations dissociated into pairs of a/3(112) superpartials with SISF between them.The theoretical and experimental micrographs are in good agreement under various diffraction conditions.更多还原
