Textbook Question
Chapter 4, Problem 4.76DP
You would like a metal plate with good weldability. During the welding process. the metal next to the weld is heated almost to the melting temperature and, depending on the welding parameters, may remain hot for some period of time. Design an alloy that will minimize the loss of strength in this “heat-affected zone”s during the welding process.
