详细介绍
- VickersMicrohardnessofCopper，标准物质 有效期： 无 标准值： 无 Bright copper - Hardness (Vickers)
This Standard Reference Material® (SRM®) is intended primarily for use in calibrating Vickers-type microhardness
testers and is certified for mean Vickers hardness values (HV) at loads of 0.245 N, 0.49 N, and 0.98 N (0.025 kgf,
0.050 kgf, and 0.100 kgf, respectively). SRM-1894a consists of a 1.35 cm square test block of electrodeposited
bright copper, approximately 1750 μm thick, on an AISI 1010 steel substrate, mounted in a thermosetting epoxy.
Five indentations were made on the SRM’s polished surface for each load. Hardness values are reported in
Gigapascal (GPa) and kgf/mm2. The SRM® was individually measured and bears a serial number imprinted on
the side of the epoxy mount.
