Update: Titanium alloys are typically etched using a grain boundary etchant such Kroll’s or 2% HF. In the case of alpha case evaluations, a tint etch such as ammonium fluoride is used to provide greater contrast between the alpha...
So this post be a bit outside the typical scope of this blog being that it’s not technically metallography. Silicon carbide is a semiconductor which takes the form of hard grains that are often used to manufacture abrasives. These...
Alpha-beta titanium alloys are commonly used in aerospace applications where high strength and low weight are key performance drivers. Alpha beta titanium alloys are capable of matching the strength of high strength steels while having nearly half the mass....
One of the first true superalloys was A286 super stainless steel which was developed in the 1930s. The superalloys of this era consisted of mostly iron or nickel base alloys with additions of chromium for oxidation resistance. However, with...
People often ask me what my favorite metal is. For that, I don’t really have an answer since I tend to think in terms of an application. However, I will say my favorite microstructure is that of duplex stainless...
Aluminum is a material that is often used for its strength toweight ratio, good machinability, corrosion resistance, and cost. Aluminum 6061is the most commonly used aluminum alloy. It contains magnesium and silicon asits primary alloying elements and is precipitation...
