摘要

采用钛近α合金Ti-6Аl-2Zr-1.2Мо-1.3V，采用扩散键合法制备了多层层压板。层压板由13张纸组成，以一种它们都有共同的滚动方向的方式相互堆叠。研究了试样切割方向对层合板冲击载荷下力学性能的影响。对所研究试件冲击断裂特征的定量评价结果进行了分析。横向试件的冲击强度值高于纵向试件。断口学研究结果表明，在断裂试样的表面存在轻微的分层。

Impact fracture characteristics of multilayer laminate based on near-alpha titanium alloy

Titanium near-alpha alloy Ti-6Аl-2Zr-1.2Мо-1.3V was used to manufacture a multilayer laminate by diffusion bonding. The laminate consisted of thirteen sheets stacked relative to each other in a way that they all had common rolling direction. The influence of cutting orientation of specimens on the mechanical behavior under impact loading of the laminate was determined. The results of quantitative assessment of the impact fracture characteristics for the studied specimens was analyzed. The transverse specimens had a higher impact strength value in comparison to the longitudinal specimens. The results of fractographic studies showed the presence of minor delaminations on the surfaces of fractured specimens.

期刊介绍： The aim of "Letters on materials" is to provide a fast publication of short research and review articles on various topics in materials science and related areas of material physics and mechanics. The editorial board sees it''s own task in rapid informing of the readers on the state-of-the-art challenges and achievements in materials science. The editorial board does its best to select high quality papers reporting new scientific results that are of interest for researchers in materials science, physics, and mechanics. "Letters on materials" invites Russian and foreign researches to publish papers in both the Russian and English languages. The scope of the journal covers the following research areas: structure analysis of materials, mechanical and physical properties of materials, production and processing of materials, experimental methods of investigation of materials, theory and computational methods in solid state physics. "Letters on materials" is designed for researchers, engineers, lecturers, and students working in the areas of materials science, mechanical engineering, metal forming, physics, and material mechanics.
