Abstract

A new technique for examining composites by means if ultrajet diagnostics is considered. The scientific approach is based on imitating material fatigue tests in accelerated mode and evaluating composites for adhesive strength at alternate loads. Ultrajet diagnostics will allow ensuring the performance adequacy of resource strength calculations while designing items from composites by rapidly determining the necessary parameters of physical mechanical properties in the course of their design and process development. A Ti6Al4V titanium alloy powder sample made by selective laser melting is used as an example to show that the geometric parameters of hydroerosion are associated with the surface defects of the sample, its stress–strain state and the in-growth path and direction followed by the scanning laser beam.

摘要

如果考虑采用超喷射诊断技术，则是一种用于检查复合材料的新技术。科学的方法是基于模拟加速模式下的材料疲劳测试，并评估复合材料在交替载荷下的粘合强度。Ultrajet诊断程序可以通过在复合材料的设计和工艺开发过程中快速确定其物理机械性能的必要参数，来确保从复合材料设计物品时确保资源强度计算的性能足够。以通过选择性激光熔融制备的Ti6Al4V钛合金粉末样品为例，表明水蚀的几何参数与样品的表面缺陷，应力-应变状态以及向内的生长路径和方向有关。扫描激光束。
