The fully consolidated bilayer (consisting of two amorphous Al₈₆Ni₉Gd₅ ribbons) and trilayer (composed by the Al_95.1Cr_2.5Mo_1.4Ti_0.4Zr_0.3V_0.3 crystalline melt-spun ribbon placed between two amorphous ribbons) disks of 5 mm in diameter were fabricated by unconstrained high pressure torsion (HPT) processing up to four turns at applied stress of 2 GPA. The structure of the cross sections of the trilayer disk was analyzed by scanning electron microscopy and the critical strains required for partial and full mixing of the amorphous and crystalline ribbons were estimated. HPT processing of amorphous ribbons resulted in formation of Al nanocrystals about 8–9 nm in size and essential enhancement in microhardness from 2.7 to 4.1 GPa after one turn. The averaged surface microhardness of the firstly consolidated trilayer amorphous/crystalline disks increased from 2.3 to 4.7 GPa with increasing of up to 4 turns. The strain-hardening of these disks was caused by a simultaneous increase of the volume fraction of Al nanocrystals up to 0.41 and a decrease in their sizes from 41 to 14 nm. The internal structure of the HPT processed trilayer disks was strongly inhomogeneous and its microhardness varied in the range from 2.86 GPa in the central part to 6.45 GPa in the zone of partial mixing which was an exceptionally high value for Al-based alloys.

完全固结的双层结构（由两个无定形的Al ₈₆ Ni ₉ Gd ₅带组成）和三层结构（由Al _95.1 Cr _2.5 Mo _1.4 Ti _0.4 Zr _0.3 V _0.3组成通过在2 GPA的施加应力下进行多达四圈的无约束高压扭力（HPT）处理，制造了直径为5 mm的两个无定形带之间的结晶熔纺带。通过扫描电子显微镜分析三层盘的横截面结构，并估计非晶和结晶带的部分和完全混合所需的临界应变。非晶带的HPT处理导致形成了大约8–9 nm的Al纳米晶体，并且在转一圈后从2.7 GPa到4.1 GPa的显微硬度得到了显着提高。首次固结的三层非晶/晶体盘的平均表面显微硬度从2.3 GPa增加到4.7 GPa，最多增加4圈。这些圆盘的应变硬化是由于同时增加Al纳米晶体的体积分数至0.41和其尺寸从41 nm减小到14 nm引起的。HPT处理的三层盘的内部结构非常不均匀，其显微硬度范围从中心部分的2.86 GPa到部分混合区域的6.45 GPa，这对于Al基合金而言是非常高的值。
