TEM AND COMPUTER IMAGE SIMULATIONS ON SUPERDISLOCATIONS IN ROOM TEMPERATURE DEFORMED Al_(67)Mn_8Ti_(25) ALLOY
L12型Al3Ti合金室温变形超位错的分解及计算机图像模拟

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.
