Test Background
Sintered metal porous materials are a functional material that is developing rapidly at present. It has the advantages of good permeability, adjustable pore size, corrosion resistance, high temperature resistance, and high strength. It can be made into filters, separation membranes, silencers, catalyst carriers, battery electrodes, flame retardant and explosion-proof materials, and has been widely used in atomic energy, petrochemical, metallurgy, machinery, medicine, environmental protection and other industries.
The tensile strength test of sintered metal porous materials can determine the compressive properties of sintered metal porous materials. Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various sintered metal porous materials, and provides professional tensile strength testing services for sintered metal porous materials.
Scope of tests
1. Applicable to sintered metal porous materials produced by powder metallurgy methods, including sintered metal fiber porous materials, sintered metal powder porous materials and metal foam materials; not suitable for dense metal materials.
2. If you need to test the compressive elastic modulus and compressive yield strength, you need to set the unloading parameters in the elastic stage if necessary. In order to achieve unloading in the elastic stage, the unloading parameters can be adjusted according to the characteristics of the specimen. If the unloading curve does not meet the requirements, new samples are allowed to be used for repeated testing.
Test method
The sample is subjected to axially increasing unidirectional compressive force, and the force and deformation can be detected continuously or in limited increments, and then one or more specified compressive mechanical properties can be measured.
