- In welding of metals, molten metal is deposited between the two objects that are to be welded together. Most of the heat from the molten material is conducted into the area around the weld, significantly increasing the temperature in the area, which can affect the local material properties. This area is often called the Heat Affected Zone (HAZ). Assuming you have base metal that is hypereutectoid steel, with a Cementite+Fine Pearlite microstructure, estimate what the microstructure would be in Area 1 and Area 2 of the HAZ. What is the primary factor (other than temperature and composition) that would affect what type of microstructure would be created?arrow_forwardNi-W alloys are widely used in tape form, i.e., sheets that are a hundred microns thick and several hundred meters long. A. A starting sheet of Ni-W alloy cannot be cold-rolled into a tape in a single pass. Instead, cold-rolling steps must be alternated with annealing steps. Why? B. Consider a fully-annealed, 1 cm-thick, 1 m-long sheet which is cold-rolled to a 7-mm thickness. What is the %CW? Assuming that the width does not change, how long is the sheet after rolling? C. Now consider an identical starting sheet that is rolled to a 3-mm thickness. How do the yield strength, tensile strength, and ductility of this rolled sheet compare to the previous one? D. If the maximum amount of cold work that can be done in a work-annealing cycle is 70%CW, how many cycles are required to roll the Ni-W alloy sheet to a thickness of 50 μm?arrow_forwardExplain why 1. using tin in food production. 2. using aluminum in overhead cables 3.
