Additive Manufacturing from Start to Finish

July 14, 2023

For much of human history, parts manufacturing was subtractive. The unformed material would have parts cut away to achieve the desired results. However, in the 1970s, a new manufacturing revolution was beginning. Computer-aided designs (CAD) was able to guide lasers pointed at liquid plastic, fusing it into solid plastic. Ultrafine layers were added to the product, creating, for the first time, additive manufacturing.

Sports Development Starts in the Lab

March 31, 2023

When you think of a sports competition, you may picture several athletes at the tops of their game duking it out for supremacy, whether on a pitch, a track, a course, a pool, or wherever else their sport takes them. But sport competitions can transcend humans challenging each other. The competition in the sports equipment industry is just as fierce as that between players.

Precision vs Speed: Are They at Odds?

January 27, 2023

In the race between the tortoise and the hare, which style of instrument analysis is best for your lab? Slow and steady or fast and loose?

Avoiding Embrittlement with the H836EN

November 4, 2022

In 2013, as the eastern span replacement of the San Francisco-Oakland Bay Bridge was drawing to a close, 277 vertical steel rods to improve the seismic stability of the replacement were tested under tension using three-inch-diameter bolts. Within two weeks, 32 of the steel rods had snapped. 277 of these rods were used in the $6.5 billion construction project, but only 96 were accessible. Metal testing suggested hydrogen embrittlement during the manufacturing of the rods may have caused the failures. Thankfully, this was able to be corrected before the bridge opened, but it was a major setback in the construction.

All About Aluminum: The New H836EN

May 20, 2022

Once more expensive than gold, aluminum has not lost its value over the years, only its price tag. Thanks to revolutionary methods of production largely developed in the late 1800s, the price of aluminum dropped from $34 an ounce in 1852 ($1,276 in 2022 dollars) to just $0.09 an ounce today. As a low-density, high-strength, corrosion-resistant metal, aluminum's usefulness has led to incredible consumption in many industries from transportation to packaging.

Ferroalloy Factors: Oxygen and Nitrogen Determination

March 18, 2022

Most iron products these days are improved with the addition of ferroalloys, or iron alloys containing high levels of other primary elements. Ferroalloys are everywhere from cast iron to stainless steel. These extra elements help strengthen the metal by adding their own characteristics: silicon is used to deoxidize steel, manganese mitigates harmful effects of sulfur, and chromium increases corrosion resistance, to name just a few. But adding to iron is not without risk; if unwanted elements are part of the ferroalloy, they can weaken the resulting products.
