Research on Transformation from Brinell Hardness to Leeb Hardness Based on Artificial Neural Network;

Analysis on uncertainty and errors of Leeb hardness test;

Conversion Relation of Leeb-hardness,Vickers-hardness and Strength of Austenitic Stainless Steels

In the paper,based on the experiment results the transformation relations between Leeb-hardness and tensile strength are obtained through linear regression and nonlinear regression.

The Leeb hardness tester as well as its features,typical applications,development and proper type selection were introduced.

Using G type Leeb hardness tester to test the hardness of low strength structural steel sheets, the hardness number is often lower.

Combining with the situation of existing error in hardness measurement by Leeb Hardness Tester,this paper introduces the measuring principle of leeb hardness tester and analyzes the influencing factors of measuring error such as surface roughness of specimen,specimen thickness and the distance between measuring points,and proposes some corresponding preventive measures.
