How Quenching Hardens Steel in Metalworking
9/8/2019· After the metal is tempered, it is cooled quickly, slowly, or not at all, depending on the circumstances, particularly whether the metal in question is vulnerable to post-temper brittleness. In addition to the martensite and austenite temperatures, heat treatment of metal involves the ferrite, pearlite, cementite, and bainite temperatures.

Galvanization - Wikipedia
Galvanization or galvanizing (also spelled galvanisation or galvanising) is the process of applying a protective zinc coating to steel or iron, to prevent rusting.The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten hot zinc.
Spark testing - Wikipedia
Spark testing is a method of determining the general classifiion of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted. These sparks can be compared to a chart or to sparks from a known test sample to determine the classifiion. Spark
Advantages and Disadvantages of Metal Cored Wires
Metal cored wires are classified under the American Welding Society specifiion with solid MIG wires (AWS A 5.18-93 for mild steel, AWS A5.28-98 for low alloy and AWS A5.9-93 for stainless steel). Metal cored wires will carry the same basic classifiion for strength level and chemical composition as solid MIG wire, but are denoted by a “C” for composite wire.
Corrosion - Properties of metals - National 4 Chemistry …
Corrosion A metal object corrodes when it is exposed to the open air and bad weather. If the metal is iron, we call this change rusting, and the weaker, flaky brown compound that is formed is rust
Lab 1 - Density Determinations and Various Methods to …
In this experiment, you will measure masses and volumes to determine density. Four different metal cylinders are investigated. In parts 1-3, three different methods are used to find volume of two solid metal cylinders (Al and brass). Each method has its own
What is the pH Scale?, explaining indiors colours, …
(2) Starting with 25-50 cm 3 of a dilute hydrochloric acid solution, add powdered calcium oxide (lime) or calcium hydroxide (slaked lime) in small portions at a time. Again, follow the pH as it rises from pH 0-1 to pH 7 (neutralised) and then rising further to ~pH 13 with excess of the calcium oxide/hydroxide alkali.
Aluminum is a shiny grey metal and has a clear oxide that forms on contact with air. This may not be the best thing for identifying it, but aluminums melting point is 658 C (1217 F). Also aluminum is non sparking. Aluminums density is 2.70 g/cm 3, this is a good way to identify it because you can find the density of a material by density = mass ÷ volume.
