This second edition cancels and replaces the first edition (i.e. ISO 3312:1975). Specifies a method for the determination of the dynamic (adiabatic) Young moduls by longitudinal oscillations of sintered metal materials and hardmetals. Gives principle, symbols and units, apparatus, preparation of the pieces, procedure, expression of results and test report.
Abstract
Overview
ISO 3312:1987 specifies a laboratory method for determining the dynamic (adiabatic) Young’s modulus of sintered metal materials and hardmetals (cemented carbides) by excitation of longitudinal ultrasonic oscillations. This second edition (1987) replaces ISO 3312:1975 and defines the principle, symbols and units, required apparatus, specimen preparation, test procedure, calculation of results and test-report content.
Key topics and requirements
- Test principle: Excite specimens with ultrasonic longitudinal vibrations, identify the resonance frequency corresponding to the fundamental longitudinal mode, and calculate dynamic Young’s modulus from measured parameters.
- Specimen geometry: Minimum length 60 mm; acceptable cross-sections:
- Cylindrical: diameter 6 ± 0.2 mm
- Rectangular bar: (6 ± 0.2) mm × (8 ± 0.2) mm
- Surface and dimensional tolerances:
- Remove surface layer to at least 0.1 mm.
- Surface roughness Ra
