Metals - Metallurgy of Welding - Down and Dirty Style
Metallurgy is the study of metal. Welding Metallurgy is the study of how welding affects the microstructure of metal. Did you know that there are metallurgists who devote their lives to only studying carbon steels? So what about all the other metals like Stainless steel, nickel alloys, aluminum, magnesium, titanium, cobalt, and copper alloys? Metallurgy is such a deep and mysterious subject that it takes a lifetime to completely understand carbon steels much less all the rest. So if is such a deep subject, what chance does a welder have in understanding enough about metallurgy in order to be a better welder. There is good news. And its not that I saved a bunch of money on my car insurance by switching to GEICO. The good news is that you dont have to understand everything about metallurgy.

Powder Metallurgy - Basic Information
Powder metallurgy was formerly known as lost art. Not like clay or other stoneware materials, the skills in molding and firing useful and ornamental metallic objects were seldom applied in the early phases of history. Metal powders like gold, copper and also bronze and many other powdered oxides specifically iron oxide which are used as colors, were utilized for ornamental uses in ceramic objects, used as base in paints and inks and also in cosmetics since the start of history. Powdered gold has been used in illustrating several manuscripts in the early times. The procedure in producing the powdered gold was not known, but it was possible that lots of powder were taken through granulation after the melting of the metal. Low dissolving points as well as resistance to corrosion favored the procedures, particularly in production of gold powder.

Revolutionary VAC Software: Ford s New Edge
Today s Ford s powertrain cost operations is slashed by the discovery of its revolutionary software called VAC. Virtual Aluminum Castings or VAC software was developed by Ford to aid in designing cast components. Said software is capable of pointing out potential stress points in parts for cylinder heads and engine blocks while they are still on the drawing board. Hence, the process is made simplified and more effective. VAC cuts down the expenses allotted for Ford car parts design purposes. Aside from that, the trial and error stage is spared. Hence, the automaker can save so much time which can be used for other vehicle manufacturing needs and demands. The VAC software has helped Ford create the new 3.5 ndash liter V ndash 6 engine s cylinder head. It is used to power the new Ford Edge.

The Advantages of Designing Products of Plastics
It has been nearly 40 years since Mr. McGuire took the recent graduate, Benjamin, aside from the pool party and whispered that one word, plastics. We ve come a long ways in knowing what can and can t be made of plastics, and have both wild successes and dismal failures in applying these fascinating new substances to our everyday commercial and industrial products. Savvy engineering skills in applying plastics can make or break a product design. There was a time when things made of plastics were considered cheap and flimsy. Not so any more. New polymers have greatly expanded the horizons of possibilities. We board a jet to cross the Pacific made mostly of plastics. The frontal armor of an M ndash 1 Abrams battle tank contains plastics, and previously unattainable temperatures and pressures of our power transmission equipment rely on plastics.

Sand Cast Bronze Sculpture
Go for the bronze! Why settle for gold or silver when you can have artwork and sculpture crafted by bronze sculpture experts? When you purchase bronze artwork, you know that it s a product that took careful design, intricate planning and fine craftsmanship to produce. Since ancient time artists have employed different techniques to make bronze figures, animals, candlesticks and other pieces of art. Bronze casting is highly skilled work, requiring vast knowledge about design, metallurgy, and casting techniques. Bronze products are cast from molds. The mold is created from a detailed model of the finished product. Hot molten bronze is poured into the mold and allowed to cool to produce the work of art. The mold is then removed and the artwork is then ready for the finishing touches. It sounds simple, but it s not.

Applying Ancient Indian Wisdom
Handicraft is described as something made entirely by hand, without technological help. This has been done in India for at least 5000 years. Although some stone and bone weapons have been found that predate the oldest handicrafts, these are not considered handicrafts. India s history of arts and crafts is interesting, covering thousands of years and millions of square miles. Indian traditional handicrafts revolve around the needs of commoners, patrons, royalty, religious beliefs, and domestic and foreign trade. The earliest proven archaeological discoveries of Indian handicrafts date back to the Indus Valley civilization circa 3000 B.C. At this time Indian craftsmen excelled in making jewelry, pottery, beads, terracotta, and weaving. This period represents a significant technical advancement in the field of handicrafts, as evidenced by excavations in Mohenjodaro, Lothal, Kotdigy, Dholaveera, Harappa, and others.

Knife Steel - Hold an Edge Verses No Rust
Knife steel is a critical component of the custom knife. Making a fine homemade knife is a work of patience, and a dedication to precision craftsmanship. A custom knife maker must understand the science of metallurgy when choosing an appropriate knife steel. To rust or not to rust, that is the question. Actually, that is only one of the questions. To maintain a great edge, or not to maintain a great edge is another important question! Many custom knife makers are finding middle ground for those two questions. High carbon and stainless steels are both acceptable if properly alloyed. The high carbon steels are typically the steels that are forged. They can be differentially tempered. This property gives the knife maker more options. He can better control the hardness of the cutting edge, and still have a tough knife with a springy back.

Silver Jewelry History
Asia Minor And Its History And Legends Legends are usually just that, legends. However, some legends have more truth than you might know. For the ancient Greeks, the legendary Caucasus Mountains marked the beginning of the ends of the Earth, and a fitting prison for the enemies of Greece. This is told in the tale of the Greek god Prometheus, who spent eternity chained to Mount Caucasus after stealing fire from Mount Olympus and giving it to mankind. But unlike the symbolism of Prometheus tale, the Caucasus Mountains were, and still are very real. Rich in Silver, the vast Caucasus mountain range stretches across present ndash day Armenia, Azerbaijan, Georgia and Turkey. In time, the Caucasus silver, electrum, gold and gemstone laden rivers gave birth to legends of monsters and heroes.

Beryllium
The Department of Health and Human Services (DHHS) and the International Agency for Research on Cancer (IARC) have determined that beryllium is a human carcinogen. The EPA has determined that beryllium is a probable human carcinogen. EPA has estimated that lifetime exposure to 0.04 g m 179 beryllium can result in a one in a thousand chance of developing cancer. While solid beryllium is not harmful, the dust created as result of working with beryllium metal, metal oxides, alloys, ceramics, or salts can be deadly. If ingested into the lungs the dust can cause scarring leading to beryllium disease and lung cancer. Beryllium disease is. An estimated 2 ndash 6 of workers exposed to beryllium eventually develop beryllium disease and up to one third will die as a result. Once exposed to beryllium there is a lifelong risk of developing Acute Beryllium Disease (ABD).

Kawasaki Motorcycles - Independent in Thoughts and Actions
The story of Kawasaki Company goes back to 1924, at that time involved into metallurgy and the aircraft industry. In 1949, they decided to enter the motorcycle industry producing engines that could be adapted to motorcycles. FIRST KAWASAKI MOTORCYCLES PRODUCTS a Motorcycle Engines In their line you could find a 60 cc two ndash stroke, as well as a 150cc and a 250cc four ndash stroke engines developed with technology from BMW company whom with they had had relationships since their beginnings in the aeronautical industry. It wasn t until 1954 that Kawasaki Motorcycles produced their first complete motorcycle under the name of Meihatsu (a subsidiary of Kawasaki Aircraft Co.). Almost at the same time, they also tried to introduce their own line of scooters to the market, but they soon realized they couldn t compete against the two giants of the scooters industry for those days: the Fuji Rabbit and the Mitsubishi Silver Pigeon.
