Finally, the technician may examine the fracture surfaces to determine the “% shear.” Shear technically implies ductility at both macro and micro scales, although the test method does not require anything more than a visual check using the eyeballs.

If the material is low on hardness or even totally soft, it is usually incorrect material. This can have occurred either by selection at the merchant or mixed at the purchaser’s operation.

Among us trade lobbyists in Washington, D.C., rumors are increasing that President Biden might make an announcement in the coming weeks over the future of tariffs on Chinese imports. The current administration has thus far maintained the policies of the previous – 25% tariffs on roughly 7,000 imported goods and 7.5% on over 3,000 products.

One of the eight types of corrosion is galvanic corrosion. This occurs when two dissimilar metals are in contact, particularly when exposed to a corrosive medium.

One of most important technical issues that a fracture analyst must deal with is evaluating whether the crack was ductile or brittle. Here we are talking about visible characteristics revealed to the human eye, and we are strictly discussing structures with features that are readily viewed with the human eye.

In a one-line order issued on May 26, the U.S. Supreme Court upheld the Biden administration’s continued use of the social cost of carbon, which applies a dollar amount for each ton of carbon dioxide emitted. The EPA uses this calculus to develop and justify rules that regulate emissions from utilities, vehicles, manufacturing plants and other sources.

The Office of the U.S. Trade Representative (USTR) is accepting comments from supporters of the 25% and 7.5% tariffs on Chinese imports on whether to continue the Section 301 action. If USTR receives a request for continuation, as is expected, it will conduct a full review of the tariff actions where opponents and supporters of individual tariffs can weigh in.
