Getting Control — Let’s Start with PID

It does not matter what thermal treatment work piece requires, proper control is the foundation for repeatability and quality processing. For heat-treating processes, there...

Carburizing

While some heat treatments are used to soften the material or improve its machinability, most are processed to obtain strengthened or hardened properties. The...

How did we get where we are today?

Having worked in the heat-treating industry for 58 years, I agreed in January 2011 to write a monthly column about all things heat-treating for...

Microstructural evolution, its effect on Ti6Al4V alloy

Titanium alloys are extensively used in aerospace, petrochemical, marine, and medical applications, thanks to their superior strength-to-weight ratio at elevated temperature, corrosion resistance, and...

Hardness scale conversion
