availability and the difficulties in the preparation of metallic scandium‚ which was first done in 1937‚ it took until the 1970s before applications for scandium were developed. The positive effects of scandium on aluminium alloys were discovered in the 1970s‚ and its use in such alloys remains its only major application. The global trade of the pure metal is around a hundred pounds a year on average.[3] The properties of scandium compounds are intermediate between those of aluminium and yttrium. A diagonal

corrosion of different kinds of implants used as cardio stents‚ orthopedic and dental implants. As the materials used for these implants are manifold starting from metallic materials such as stainless steel (SS)‚ cobalt chromium‚ titanium and its alloys‚ bioceramics‚ composites and polymers are in constant contact with the aggressive body fluid‚ they often fail and finally fracture due to corrosion. The corrosion behavior of various implants and the role of the surface oxide film and the corrosion

The Metal Casting or just Casting process may be divided into two groups: Hot Forming Process Examples are Centrifugal casting‚ Extrusion‚ Forging‚ Full mold casting‚ Investment casting‚ Permanent or Gravity Die casting‚ Plaster mold casting‚ Sand Casting‚ Shell Mold casting. The method to be used depends upon the nature of the products to be cast. Cold Forming Process Examples are Squeeze casting‚ Pressure die casting‚ Gravity die casting‚ Burnishing‚ Coining‚ Cold forging‚ Hubbing‚ Impact

The SEM examination of the pre and post polarized alloy surfaces provided evidence which was consistent with the electrochemical measurements‚ in that the first three alloys exhibited no appreciable corrosion damage whereas pitting corrosion was observed on Nitinol. The results obtained from x-ray analysis of the pitted surface indicated that this pitting could

Abstract This experiment will explain what the Rockwell hardening test is and why it is used‚ how the experiment was conducted‚ data that was found‚ and the importance of testing the hardness of materials. This experiment explains and proves how the hardness of materials can be increased by alloying and heat treating. Intro – Rockwell Hardness Testing Soft and hard qualities exist in materials. In materials‚ hardness measures the ability of a material to resist scratching‚ indentation‚ or penetration
