The Vickers hardness test method involves indenting the test material with a diamond indenter in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces (Fig.
The popularity of this test spawned a number of test scales, including the Vickers hardness test (1921), the Rockwell test scale (conceived in 1908), and the Knoop hardness test (1939).
The mold hardness test is similar to the Brinnel hardness test used on metal castings, where a ball or point is pushed into the mold surface to measure 'pushback' resistance.
This was to provide the field hardness test approach and general evaluation procedure for reliably determining the yield strength for older pipe of unknown specification.
Most standard hardness tests for steel, including the Brinell, Vickers and various Rockwell tests, are generally classified as bench testers.
In general, traditional hardness tests consist of the application of a single static force and corresponding dwell time with a specified tip shape and tip material, resulting in a hardness impression that has dimensions on the order of millimeters.
There are several types of hardness tests, including the Brinell test, the Rockwell test, the Vickers test and the durometer test.
Hardness tests are used mainly as a simple, rapid, nondestructive test for quality control in production, and as a measure of mechanical properties affected by changes in chemical composition, microstructure and aging.
The main advantage of these hardness tests is their easiness, repeatability and also the fact that in many cases the measurement can be performed directly on the product or on samples produced and designed for other types of mechanical tests.
All hardness tests should be done with care and with suitable controls.
The Model 1600 Multi-Scale durometer test kit is available for the technician who must perform hardness tests on various types of non-metallic materials.
Further, ME Global offered a complete metallurgical evaluation [microstructure, ultimate tensile strength (UTS) results, RT analysis, Brinell hardness tests, etc.
The complicated moving boundary problem in Rockwell hardness tests is simplified to an intermediate stationary one for a flat die indenter using principle of similarity and cumulative superposition approach.
A fixture from Indentec halves setting times by enabling both external and internal hardness tests to be made on drive-shaft hubs without removing them from the test table.
