Creep deformation mechanisms in 9CrMo steel

The Generation-IV reactors in nuclear power plants are expected to address the growing energy demand by producing electricity and, at the same time, mitigating...

Aluminum heat-treating has unique challenges

From a metallurgical and quality perspective, aluminum heat-treating presents unique challenges when compared to carbon-based steels. This article will examine the aspects of aluminum...

Q&A with Adam Jacobson

What’s a typical day like for you at JN Machinery? We’re a small company, so, it really depends on what’s going on as far as...

Combatting undesirable NMTP formations

Whether formed during a conventional quench and tempering process, carburizing, or induction hardening, non-martensitic transformation products (NMTP) are widely considered undesirable microstructural features. However,...

A technical guide to quenching

From a quality perspective, verification of the conformance of quench requirements can be accomplished by examining a furnace chart that shows the quench trend....

Thermal triplets: PM, sintering, and case hardening

From my experience, powder metals (PM), sintering, and case hardening are three processes that could be said to be joined at the hip. More...

The importance of contract review

Within any aspect of our business structure, understanding the specific requirements needed to produce product that conforms to customer requirements is important. These requirements...

Enhanced properties of metal matrix nanocomposites

Application of carbon nanotube (CNT) reinforced metal matrix nanocomposite (MMNC) has been increasing rapidly since the discovery of CNT in the 1990s. These novel...

Q&A with Steve Mueller

What does Praxair do for the heat-treat industry? Praxair produces and sells industrial gases, such as nitrogen, argon, hydrogen, and helium. Our main focus for...

How to keep decarburization in check

The performance of heat-treated steel components is largely dependent on the condition of their surface. Wear and fatigue resistance are examples of design criteria...

Method means comparing checklists vs. procedure

Whether commercial heat-treating or captive, procedures are essential to the production of conforming product and its repeatability. Procedures can be challenging to write at...

Q&A with Eric Ford
