A study of the mechanical properties of amorphous iron-based alloy produced by the injection-casting method

摘要

Purpose: The paper present determine the basic mechanical properties of amorphous alloy based on iron (Fe61Co10Zr5W2Y2B2), produced by injection. Design/methodology/approach: The study was carried out the following steps: at fist microhardness were performed with using microhardness tester Future Tech FM 7 by Vicker's method with load 970.7 mN. Second step were performed abrasion tests on ball-tester with zirconium ball. These tests were performed in 3 steps - first (study was conducted in one hour), second (study was conducted in two hours), third (study was conducted in three hours). Third kind of study was roughness performed on profilometer Hommel T1000. The sample surface was examined in the section 4.8 mm. After high-resolution photos were then taken with a scanning electron microscope (JEOL JSM - 6610 LV). In contrast images with areas threadbare, made using an optical microscope Axiovert 25. Findings: Tests results of samples in of the alloy (Fe61ColOZr5W2Y2B2) in the form of plates were confirmed higher microhardness amorphous alloy than material with same chemical composition but with crystalline structure. Originality/value: Receipt of amorphous alloys with unique mechanical properties for electronics applications.
