Widia

Widia may refer to:

Wudga

Wudga (Old English: Wudga, Widia; Middle High German Witege or Witige; Gotho-Latin: Vidigoia; Proto-Germanic: *Widigaz) or Vidrik "Vidga" Verlandsson (Old Norse: Vidrīk + Viðga or Videke + Verlandsson, Vallandsson, or Villandsson) is a hero in several early Germanic legends and later Scandinavian ballads.

In Legends about Theoderic the Great, he was of Dietrich von Bern's warriors. In one of the ballads, he won particular fame in his duel with Langben Rese/Risker.

During the Middle Ages, he became the son of Wayland the Smith and Böðvildr, and this entitled him to carry a hammer and pliers in his coat of arms. Later the origin of his name "Wayland's son" was forgotten, but the fame of the character prevailed. During the 16th and the 17th centuries, this led to the idea that his name "Villandsson" referred to Villand Hundred in Skåne, and the hundred duly began to use his coat of arms as its own. Wudga wielded the sword Mimung, forged by his father, as was the helmet he wore. His mount was the stallion Schimming, one of the finest horses of its age.

Cemented carbide

Cemented carbide is a hard material used extensively in cutting tools for machining, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites.

Most of the time, carbide cutters will leave a better surface finish on the part, and allow faster machining, than high-speed steel or other tool steels. Carbide tools can withstand higher temperatures at the cutter-workpiece interface than standard high-speed steel tools (which is a principal reason for the faster machining). Carbide is usually superior for the cutting of tough materials such as carbon steel or stainless steel, as well as in situations where other cutting tools would wear away faster, such as high-quantity production runs.
