Steel has some fire resistance which is determined by the size of the section, the degree of exposure and the load that it supports. The temperature to failure for steel is directly proportional to the load. The greater the load, the lower the yield or failure ..............

Q: Experimental results show that in EBW the penetration depth of the weld decreases as the welding…

A: EBW stands for Electron Beam Welding, which is a high energy welding process that uses an electron…

Alloys

An alloy is an admixture of two or more metals or a metal and a non-metal. Since ancient times, man has been using alloys. Alloying helps to retain the properties of the parent matter, such as hardness, strength, toughness, ductility and is corrosion-resistant. Copper alloys such as brass have antimicrobial properties that help to fight against (Coronavirus disease 2019) COVID-19 and other hospital-acquired infections. Some common alloys are brass, bronze, solder steel, etc. Most alloys have a lower melting point than their constituents. This is due to the presence of a nonmetal as one of the constituents that behaves as an impurity and restricts the raise of melting point.
