ISO 17340-2020 金屬材料--延展性試驗--多孔泡沫金屬的高速壓縮試驗 Metallic materials — Ductility testing — High speed compression test for porous and cellular metals

This document specifies methods for high speed compression testing, at room temperature, of porous and cellular metals having a porosity of 50 % or more. The speed range applicable to this test method is 0,1 m/s to 100 m/s (or 1 s ⁻¹ to 10³ s⁻¹ in terms of the initial strain rate when the specimen height is 100 mm).nd edition 2020-05 Metallic materials — Ductility testing — High speed compression test for porous and cellular metals Matériaux métalliques — Essais de ductilité — Essai de compression à haute vitesse des métaux poreux et cellulaires Reference number ISO 17340:2020(E) ？ ISO 2020 ISO 17340:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2020 All rights re
