Carbide compression test method
1 Scope
This standard specifies the determination of the ultimate strength and yield carbide point compressive load under the action of the method in uniaxial.
Principle 2
The sample is placed between two hard metal bearing seat, an axial load is applied to the specimen until the specimen is expected to deformation or rupture.
3 symbols and their meanings
Symbols and their meanings are shown in Table 1.

4 Device
4.1 design and manufacturing test machine should be capable of applying the load evenly, and in consideration of the measurement range, the maximum error is loaded
± 1%.
4.2 Specimens shall be fixed between two rigid concentricity good reliable hardness of not less than 1600HV carbide support base. Sample
And the contact surface between the two bearing should be perpendicular to the loading axis, two parallel contact surfaces within 0.5μm/mm range. Figure 1 illustrates
A suitable carbide bearing seat.
5 Sample
5.1 Sample size should meet the requirements of Figure 2. Face and cylindrical surface at both ends of the specimen shall be polished surface without additional grinding (grinding or polishing
Light may affect the test results) 1).
1) with a cylindrical sample ASTME9-1977 or USSRTU-48-19-280-78 prescribed, the results may be less accurate.
