Axial and Bending Fatigue Performance of Shallow-Carburized SAE 8615 Steel

The previous blog examined the performance of SAE 8615 simulated-carburized steel in monotonic tensile tests and compared its performance in axial and bending fatigue conditions. This blog will explore the performance of SAE 8615 steel with a shallow-carburized case depth … Continue reading

Fatigue Properties of Modified Steels Carburized at High Temperatures

The objective of phase XI is to compare the performance of carburized steel in bending and axial fatigue loading conditions. Carburization is a surface heat treatment process which adds carbon to the surface of a material to increase its hardness … Continue reading

Neuber Stress Plots

This article explains how a “Neuber Stress” is calculated from fatigue test data obtained from un-notched axially-loaded specimen. In the presence of a geometric stress concentration feature on a part, the fatigue life of that part is often under-predicted as … Continue reading

Mechanical Properties versus Carburization Depth

In this article we will examine the relationship between ultimate tensile strength, fatigue strength, and elongation versus the depth of carburization. The data for this comparison was taken from several iterations discussed in previous articles and shown in Table 1. … Continue reading
