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...
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....
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...
Inconel 600 and 625 are both solid-solution strengthened nickel chromium alloys. They are used for their corrosion resistance more than their high temperature counterparts. They are commonly used in applications where corrosion and strength are of concern such...
The other day, the bolts that held on my license plate had gotten rather rusty and I wanted to prevent the rust from staining the license plate (one of my pet peeves is a dirty car). Therefore, I...
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,...
There are countless nickel-based superalloys with the most famous of them often being Inconel 718 which is often used in gas turbine applications. In fact, Inconel 718 is so commonly used in gas turbines that it often can...
There are many nickel-based superalloys with the most famous of them often being Inconel 718 which is often used in gas turbine applications. However, another commonly used precipitation hardenable nickel-based superalloy is Inconel 706. Inconel 706 is a...
Titanium and its alloys are one of the most interesting light alloys. With a high strength to weight ratio and excellent corrosion resistance titanium alloys are ideal in may weight driven applications such as aerospace and automotive racing....
