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

The Effect of Bainite on Strength and Fatigue in Through-Carburized SAE 8620 Test Bars

A case microstructure may consist of martensite, retained austenite and bainite, and depends upon alloy and cooling rate. The impact of bainite on fatigue is not well known.  Sometimes carburized parts are intentionally austempered to increase the amount of bainite … Continue reading
