Q.1. What is hot working ? State its principles, advantages and disadvantages. Ans. Mechanical working of metals above its recrystallisation temperature is known as hot working. Advantages : 1. Larger deformation can be accomplished and more rapidly by hot working since the metal is in plastic state. 2. Porosity of the metal is considerably minimised. 3. Concentrated impurities, if any in the m...

cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. in this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

in the present study, the mechanical behavior of aa5052 aluminum alloy during cold deformation and subsequent isothermal annealing in a temperature range of 225-300oc was investigated using the uniaxial tensile test data. it is found that by increasing the annealing time and temperature the material yield strength is decreased. the microstructural investigations of the annealed samples show tha...
