Abstract
Effects of the debinding atmosphere, powder characteristic, solid loading and heating rate on the compact deformation were investigated. The compact strength after thermal debinding was measured by bending mode. The experimental results indicate that the vacuum atmosphere is beneficial to improving the deformation resistance compared with nitrogen atmosphere. Small particle size, irregular particle shape and high solid loading are suitable for decreasing the deformation defects. Besides, too fast heating rate may induce deformation defects. It is also indicated that effect of the factors for the deformation defects is different in different debinding stages. The strength evolution of the compacts during thermal debinding was also discussed.
