Expert Solution

1.- Above the recrystallisation temperature, the metal becomes plastic and causes the growth of grains. By heat treatment, the grains are broken up and their parts are deformed into small and more numerous crystals or in other words the refinement of grain occurs. Metals possess little elasticity and low load is required to shape the metal as the strength and hardness decrease at elevated temperatures.

2.- The porosity of the steel ingot can be eliminated to a greater extent.

3.- Great latitude in shape and size of form is possible due to reduction of elastic limit.

4.- A uniformity is established either by squeezing other impurities into fiber slags or distributing them throughout the mass.

5.- Directional property resulting from a fiber structure is obtained.

6.- Due to refinement of grains, mechanical properties such as toughness, ductility, elongation and reduction in area are improved.

7.- The power required to finish the part ingot is less.

8.- It can be used on most of the metals, because it is a rapid and economical process.

An irreversible heat pump heats a home on a cold winter’s day. The home loses heat to the outdoors at a rate of Q̇ = B (Tin − Tout), where B is a constant equal to 0.5 [kW/K]. The coefficient of performance (COP) of irreversible heat pump is 50% of that for a reversible heat pump (i.e., β ′ = 0.5 β ′ rev ). If the indoor temperature is to be maintained at 20 °C and the power input...

USE SI UNITS Problem Statement Normalizing is a heat treatment process used to relieve internal stresses, refine the grain size and improve mechanical properties. Normalizing is done to give steel a uniform and fine-grained structure. Normalizing is often used for ferrous alloys that have been austenitized and then cooled in open air. Normalizing not only produces pearlite, but also bainite and sometimes martensite, which gives harder and stronger steel, but with less ductility than full annealing. The normalizing experiment in...
