摘要： Sputtering targets having reduced burn-in times are described herein that include: a) a machine-finished surface material having an average grain size, and b) a core material having an average grain size, wherein the machine-finished surface material has an average surface roughness (Ra) equal to or less than about the average grain size of at least one of the surface material or the core material. Sputtering targets having reduced burn-in times are described herein that include: a surface material, and a core material, wherein at least one of the surface material or the core material comprises a relatively band-free crystallographic orientation. In addition, methods of producing sputtering targets having reduced burn-in times include: providing a surface material having at least some residual surface damage, providing a core material, coupling the surface material to the core material, and machine-finishing the surface material to an average surface roughness (Ra) equal to or less than about the average grain size of at least one of the surface material or the core material. Also, methods of producing sputtering targets having reduced burn-in times include: providing a surface material combined with a core material, wherein the surface material has at least some residual surface damage and machine-finishing the surface material to an average surface roughness (Ra) equal to or less than about the average grain size of at least one of the surface material or the core material.
