Hundreds of solid state press bondings of aluminum alloy 5083 at high homologous temperatures without employing interlayers were performed to study the genuine solid state bond strength. Each press-bond work plus the preceding preparation and subsequent testing was time-consuming and laborious, so this large quantity of experiments was accomplished by three individuals. The diversity in manpower also serves the purpose that pre-bonding surface quality is not solely dependent on an individual. Four external plus one intrinsic factors on bond strength are studied: they are pre-bond surface preparation, amount of press deformation, temperature and time, as well as microstructure. Maximum bond strengths are analyzed to explore the feasibility of solid state press bonding under the presently accessible process conditions. Strength uniformity is also analyzed among these large amount of data to determine the reliability of the process. Optical and scanning electron microscopic analysis on bonding interface morphology were also performed. It is concluded that when preparing pre-bond surfaces under atmospheric environment, solid-state-press bonding of aluminum alloys can hardly achieve perfect bonding even at high temperatures.
