If it is assumed that the plot in figure is If it is assumed that the plot in figure is for noncold-worked brass, determine the grain size of the alloy in Figure 7.19; assume its composition is the same as the alloy in Figure7.15.
It is desirable to produce a copper-nickel alloy that has It is desirable to produce a copper-nickel alloy that has a minimum noncold-worked tensile strength of 350MPa (50,750psi) and a ductility of at least 48%EL. Is such an alloy possible? If so, what must be its composition? If this is not possible, then explain why.
